They are distinct from hermaphroditic animals: rather than having just the sexual organs of both sexes, these "half siders" are literally half male and half female across their entire bodies.
|
|
Snails, for example, which are hermaphroditic, begin with hours of what scientists call "foreplay," in which snail pairs get close and sniff each other before launching a sharp calcium spear that pierces their mate.

Hermaphroditic mating Cornu aspersum(garden snails). Hermaphrodites are organisms that have both male and female reproductive organs. It is possible for there to be sexual conflict within a species that is entirely hermaphroditic. An example of such is seen in some hermaphroditic flatworms such as Pseudobiceros bedfordi.
|
|
The Chaetonotids are divided into two suborders, Multitubulatina and Paucitubulatina. Multitubulatina are marine, hermaphroditic strap-shaped organisms. Paucitubulatina are mostly freshwater, bowling pin shaped organisms that can be hermaphroditic, parthenogenetic or both.

|
The older PC/104 embedded PC modules use a similar stackable format for interconnection. Stackable connectors are not classified as hermaphroditic in the strictest sense, but are often described as such in looser usage. The hermaphroditic design is useful when multiple complex or lengthy components must be arbitrarily connected in various combinations. For example, if hoses have hermaphroditic fittings, they can be connected without having to pull a lengthy hose and reverse it because it has the wrong gender to connect to another hose.
|
|
Hermaphroditic species often exhibit lower degrees of inbreeding depression than outcrossing species, as repeated generations of selfing is thought to purge deleterious alleles from populations. For example, the outcrossing nematode (roundworm) Caenorhabditis remanei has been demonstrated to suffer severely from inbreeding depression, unlike its hermaphroditic relative C. elegans, which experiences outbreeding depression.

Although most species have only two sexes (either male or female), hermaphroditic animals, such as worms, have both male and female reproductive organs.
|
|
The hermaphroditic worm is considered to be a specialized form of self- fertile female, as its soma is female. The hermaphroditic germline produces male gametes first, and lays eggs through its uterus after internal fertilization. Hermaphrodites produce all their sperm in the L4 stage (150 sperm cells per gonadal arm) and then produce only oocytes. The hermaphroditic gonad acts as an ovotestis with sperm cells being stored in the same area of the gonad as the oocytes until the first oocyte pushes the sperm into the spermatheca (a chamber wherein the oocytes become fertilized by the sperm).

Most barnacles are hermaphroditic, although a few species are gonochoric or androdioecious. The ovaries are located in the base or stalk, and may extend into the mantle, while the testes are towards the back of the head, often extending into the thorax. Typically, recently moulted hermaphroditic individuals are receptive as females. Self-fertilization, although theoretically possible, has been experimentally shown to be rare in barnacles.
|
|
Yields could be increased by improved orchard management, including pollination, and by planting high-yielding compact cultivars. Most commercial cultivars are hermaphroditic; cultivars that produce only functionally female flowers require the presence of male trees. Male trees are seldom found, as vegetative selection has favored hermaphroditic clones that produce a high proportion of functionally female flowers and a much lower number of flowers that produce pollen.
|
|
The IR model for the development of anisogamy is named after its developers Priya Iyer and Joan Roughgarden. By considering the evolution of anisogamy in hermaphroditic marine invertebrates and bisexual plants, the theory postulates of a gene locus which controls both sperm and egg size produced by an organism. Anisogamy could evolve in diploid hermaphroditic adults as an individual adaptation which increases its own fitness.
|
|
Hermaphroditic animals and dioecious plants represent a large portion of sexually reproductive species. Under social selection theory, species where individuals produce two different gametes predate strictly gonochoristic and monoecious species. Separate sexes can, therefore, be described as derivations of primal hermaphrodites. Males arising in primarily hermaphroditic species gain an advantage in certain environments as fertilizers because they lack the energy cost of producing eggs.

In addition to winemaking, grapes have been grown for the production of raisins. The earliest act of cultivation appears to have been the favoring of hermaphroditic members of the Vitis vinifera species over the barren male vines and the female vines, which were dependent on a nearby male for pollination. With the ability to pollinate itself, over time the hermaphroditic vines were able to sire offspring that were consistently hermaphroditic. At the end of the 5th century BC, the Greek historian Thucydides wrote: The period that Thucydides was most likely referencing was the time between 3000 BC and 2000 BC, when viticulture emerged in force in Asia Minor, Greece, and the Cyclades Islands of the Aegean Sea.

It feeds by breaking down and digesting the tissue of the fish within the cyst.Piper, Ross (2007), Extraordinary Animals: An Encyclopedia of Curious and Unusual Animals, Greenwood Press. Sex is determined by a region located on the mitochondrial DNA, the male open-reading frame (M-ORF) and female open-reading frame (F-ORF). Hermaphroditic mussels lack these regions and contain a female-like open-reading frame dubbed hermaphroditic open-reading frame (H-ORF).

Cutaway view of housing (side view) Powerpole connectors are physically and electrically hermaphroditic, thus avoiding the need to worry about which end is the plug and which the socket, or which end has the correct polarity. This is in contrast to the physically- but not electrically-hermaphroditic two-wire trailer plug. Powerpole connectors are available with current ratings up to 180 amperes. The size most commonly used is the 15/30/45 ampere-rated variety.

Adult snails are hermaphroditic (having both male and female reproductive organs) and can live for many years. These are live bearing snails (give birth to live snails instead of laying eggs).
|
|
In sequential hermaphrodites, where individuals function as one sex early in life and then switch to the other, the allocation decisions lie in what sex to be first and when to change sex. Animals may be dioecious or sequential hermaphrodites. Sex allocation theory has also been applied to plants, which can be dioecious, simultaneous hermaphrodites, have unisexual plants and hermaphroditic plants in the same population, or have unisexual flowers and hermaphroditic flowers on the same plant.

|
Lobelia siphilitica is an example of a species with a gynodioecious mating system. Gynodioecy is a rare breeding system that is found in certain flowering plant species in which female and hermaphroditic plants coexist within a population. Gynodioecy is the evolutionary intermediate stage between hermaphroditism (exhibiting both female and male parts) and dioecy (having two distinct morphs: male and female). Gynodioecy is the opposite of androdioecy, which is a breeding system consisting of male and hermaphroditic plants in a population.
|
|
Cytoplasmic male sterility genes, usually found in the mitochondrial genome, show up and are established when female fertility is just slightly more than the hermaphroditic fertility. The female only needs to make slightly more or better seeds than hermaphrodites since the mitochondrial genome is maternally inherited. Research done on plants has shown that hermaphroditic plants are in constant battles against organelle genes trying to kill their male parts. In over 140 plant species, these “male killer” genes have been observed.

|
|
Montipora corals are hermaphroditic broadcast spawners. Spawning typically happens in spring. The eggs of Montipora corals already contain zooxanthellae, so none is obtained from the environment. This process is known as direct or vertical transmission.
|

The hermaphroditic Schistocephalus solidus parasitizes fish and fish-eating water birds, with a cyclopoid copepod as the first intermediate host. When humans harbor plerocercoids of pseuddophyllidean cestodes outside the small intestine, it can cause sparaganosis.
|
|
The flowers are of a tubular type and hermaphroditic. The corolla is cylindrical and pink violet. The length of the flower is of 7–8 mm. The period of flowering is from June until August.
|
|
The sex organs in the induced hermaphroditic flowers become sterile as a result of infection, a process known as "parasitic castration". Ovaries become sterile because they become replaced with teliospores and form "smut balls", making the ovary unable to set seed. The anthers, however, do not show outward signs of teliospore production, but are still effectively sterile because they tend to be small and immature. Consequently, both male and female reproductive organs within induced hermaphroditic flowers of buffalograss become parasitically castrated, but for different reasons.

The General Radio Corporation developed a hermaphroditic coaxial radio frequency connector often called the "GR connector". Some audio multicore cables are fitted with hermaphroditic multipin quick-disconnect connectors for ease of use in the field. One style of this audio signal cable is fitted on both ends with connectors that are each populated half with pins and half with sockets. The advantage to the user is that it does not matter which end connects to the stage and which to the audio mixer, facilitating faster set up.

|
In question 24, Adrianus asks which creatures are hermaphroditic. Ritheus tells him these are "Belda the fish in the sea [...] Viperus the serpent and Corvus the bird". Cross and Hill argue that Belda is a scribal corruption of Latin belua ('beast'). The reading of belua as a type of sea-beast may also be a misunderstanding of the Latin etymon, since belua is a name for the hyena in earlier Latin texts - an animal understood to be bisexual (and hence symbolically hermaphroditic) at the time of their composition.

|
A unique connector configuration where the contacts are hermaphroditic is the ELCO Varicon where the contacts are bifurcated and nest with one another axial at a 90 degree rotation in cross-shaped wells. In this case the plugs had the contacts oriented transversely and the sockets longitudinally. A casual glance at a USB "Type A" plug connector may give the false impression that it is hermaphroditic. However, a physical attempt to mate two USB "Type A" cables with each other reveals the fact that the connectors will not interconnect.
|
|
Some military fiber optical cables also have hermaphroditic connectors to prevent "wrong gender" connector problems in field deployments. In a similar fashion, railcars are usually equipped with hermaphroditic railway coupling mechanisms that allow either end of the vehicle to be connected to a train without having to turn the railcar around first. For the same reason, several spacecraft docking mechanisms are designed to be "androgynous", including the Androgynous Peripheral Attach System, the NASA Docking System, and Chinese Docking Mechanism. In the absence of genderless connectors, gender changer fittings might be used to enable certain connections.

The Asian swamp eel is hermaphroditic. All young are females. As juvenile fish begin to mature, some take on the masculine phenotype. Males are capable of changing sex, allowing them to replenish female populations when female densities are low.
|
|
Most hermaphroditic species exhibit some degree of self- fertilization. The distribution of self-fertilization rates among animals is similar to that of plants, suggesting that similar processes are operating to direct the evolution of selfing in animals and plants.

Otomesostoma auditivum is a free-living, hermaphroditic flatworm in the order Proseriata, found in brackish and freshwater environments. It is a palearctic species living in shallow-water coastal habitats, and occurring in some freshwater lakes far from the sea.
|
|
It also lacks an anus, excreting waste through the same opening as it intakes food. Thus, the digestive organ is sac-like. The opening is on the belly of the animal, near the front. The animal is simultaneously hermaphroditic.
|
|
The sperm is absorbed through pores in the skin, causing fertilisation. Corals can be both gonochoristic (unisexual) and hermaphroditic, each of which can reproduce sexually and asexually. Reproduction also allows corals to settle new areas. Corals predominantly reproduce sexually.
|
|
Future breeding would be focused on processing-quality aspects, as well as on properties for better mechanization of harvest or better-yielding hermaphroditic plants. The use of modern breeding techniques is restricted due to low polymorphism for molecular markers.

|
Some nematodes, such as Heterorhabditis spp., undergo a process called endotokia matricida: intrauterine birth causing maternal death. Some nematodes are hermaphroditic, and keep their self- fertilized eggs inside the uterus until they hatch. The juvenile nematodes then ingest the parent nematode.
|
|
The posterior opisthaptor with its hooks, anchors, clamps etc. is typically the major attachment organ. Generally, monogeneans also are hermaphroditic with functional reproductive organs of both sexes occurring in one individual. Most species are oviparous, but a few are viviparous.
|
|
There are no stipules. The plants are hermaphroditic and are pollinated mostly by insects (entomophilous); flower nectaries are lacking. A few are wind pollinated (anemophilous). There is a distinct calyx and corolla, except in Macleaya where the corolla is lacking.
|
|
Herkogamy (or hercogamy) is a common strategy employed by hermaphroditic angiosperms to reduce sexual interference between male (anthers) and female (stigma) function. Herkogamy differs from other such strategies (e.g. dichogamy) by supplying a spatial separation of the anthers and stigma.
|
|
Apple snails inhabit various ecosystems: ponds, swamps and rivers. Although they occasionally leave the water, they spend most of their time under water. Unlike the pulmonate snail families, apple snails are not hermaphroditic, but gonochoristic; i.e. they have separate sexes.
|
|
Although rare, hermaphroditic samples have been collected. In these cases, the male and female follicles were in different gonadal stages, and some samples were in the spawning stages. In one case, both male and female follicles were in the spawning stages.
|
|
Groupers often pair spawn, which enables large males to competitively exclude smaller males from reproducing.Allsop, D. J. and S. A. West. 2003. Constant relative age and size at sex change for sequentially hermaphroditic fish. Journal of Evolutionary Biology 16:921-929.

An SAE connector The SAE connector is a physically genderless two-conductor DC connector commonly used for solar and automotive applications (also motorcycles). It is so named for the Society of Automotive Engineers who created the specifications this connector is based on. Although the plug is physically hermaphroditic, and any SAE connector can be connected to any other SAE connector, they are NOT electrically hermaphroditic and care needs to be taken to maintain correct polarity when connecting different plugs to each other. This connector is typically used for applying a maintenance charge to a vehicle battery.

This species is a protandrous hermaphrodite and Australian studies found that they were males at fork length of , hermaphrodites at fork lengths between FL and females are found at fork lengths of . Off the northeast cost of Queensland, most of the fish with fork lengths greater than are females. The hermaphroditic fish form once they reach 1-2-year old, and then females begin to appear at 2-3-years old. It is thought that the males change to hermaphrodites just after spawning in April and May and they remain in a hermaphroditic state until the next breeding season is over.

Lepidurus apus has an unusual life-cycle: it is able to produce microscopic cysts that can lie dormant for years at a time through extreme conditions, letting it survive in areas with vastly different climates such as Morocco and Denmark. These "resting eggs" are so drought resistant there is a record of hatching after being kept dry for 28 years. The species is hermaphroditic; no males are found in the New Zealand subspecies viridius, but in Italy there are males that are non-functional. Different subspecies of Lepidurus apus have different methods of fertilisation, some by a male, some by hermaphroditic individuals.

Fishes that give birth to live young can be ovoviviparous, where the eggs are fertilized within the female and the eggs simply hatch within the female body, or in seahorses, the male carries the developing young within a pouch, and gives birth to live young. Fishes can also be viviparous, where the female supplies nourishment to the internally growing offspring. Some fish are hermaphrodites, where a single fish is both male and female and can produce eggs and sperm. In hermaphroditic fish, some are male and female at the same time while in other fish they are serially hermaphroditic; starting as one sex and changing to the other.

J. Robinson (ed) "The Oxford Companion to Wine" Third Edition pg 276 Oxford University Press 2006 The calyptra is shed and pollen is transferred from the anthers to the stigma fertilizing the flower. Most cultivated Vitis vinifera grape vines are hermaphroditic, with both male stamens and female ovaries, while many wild grapes are either male, producing pollen but no fruit, or female, producing fruit only if a pollinator is nearby. Hermaphroditic vines are preferred for cultivation because each vine is more likely to self-pollinate and produce fruit. At the beginning of the flowering process the only part that is visible is the fused cap of petals known as the calyptra.

|
The presence of testicular lobes scattered amongst their ovaries confirmed they were in fact hermaphroditic. Fertilized females or hermaphrodites produce diapausing eggs or cysts, able to survive decades in the sediment of the ponds and lakes they inhabit. These eggs are resistant to drought and temperature extremes.

|
These are captured by the polyps, by extruding mesenterial filaments and tentacles. The polyps have nematocysts which are triggered to hold their prey immobile. The prey is then transported to the mouth with the assistance of mucus and cilia. Diploria labyrinthiformis is hermaphroditic, and reproduces through broadcast spawning.
|
|
The hermaphroditic flowers are held in cymes on short peduncles among the foliage; each flower is long, with five tiny white petals and numerous stamens. The seed pod is flat, long and wide, and contains 7–12 seeds, each of which is surrounded by a winged papery envelope.
|
|
Like many other leeches, M. montezuma is hermaphroditic. Sexual reproduction results in two individuals fertilizing each other, and the resulting eggs are placed in a nutrient-filled cocoon. The cocoon is placed deep enough to avoid the attention of ducks and other predators, and the eggs hatch into self- sufficient juveniles.
|
|
All pycnogonid species have separate sexes, except for one species that is hermaphroditic. Females possess a pair of ovaries, while males possess a pair of testes located dorsally in relation to the digestive tract. Reproduction involves external fertilisation after "a brief courtship". Only males care for laid eggs and young.
|
|
The sex of a particular organism may be determined by a number of factors. These may be genetic or environmental, or may naturally change during the course of an organism's life. Although most species have only two sexes (either male or female), hermaphroditic animals have both male and female reproductive organs.
|
|
When mature, they are light to dark brown in color with four yellowish to brownish wings characteristic of the genus. The main umbel has hermaphroditic flowers, containing both stamen and pistil. Smaller umbels may develop from the sides of the stem which usually contains only stamens. These umbels wither away quickly.

Tubifex worms are hermaphroditic: each individual has both male (testes) and female (ovaries) organs in the same animals. These minute reproductive organs are attached to the ventral side of the body wall in the celomic cavity. In mature specimens, the reproductive organs are clearly found on the ventral side of the body.
|
|
Flowers of plants in the rose family are generally described as "showy". They are radially symmetrical, and almost always hermaphroditic. Rosaceae generally have five sepals, five petals, and many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a characteristic cup-like structure called a hypanthium.
|
|
This digestive pathway is observed to be continuous throughout the entire worm. The worms are hermaphroditic, containing both male and female organs. Each worm has reproductive organs such as vas deferens, testis, uterus, vitelline duct, ovary, and vitellaria. They also have flame cells that function as a kidney and remove waste material.
|
|
The sweet-scented, hermaphroditic flowers have radial symmetry and double perianths. The five sepals, each about 2 millimetres long, are fused to one another at the base. The pink or white flower crown is star-shaped and has a diameter of about 15 millimetres. Its lanceolate petals are 7 millimetres long and 2.5 millimetres wide.
|
|
A flower of Wisteria sinensis, Faboideae. Two petals have been removed to show stamens and pistil The flowers often have five generally fused sepals and five free petals. They are generally hermaphroditic and have a short hypanthium, usually cup-shaped. There are normally ten stamens and one elongated superior ovary, with a curved style.
|
|
The flowers are hermaphroditic or unisexual; in the latter case, the male and female flowers show differences associated with the timing of pollination. They are very small (1 or 2 mm), with four yellow-green tepals and four stamens. Flowering period extends from March to June. The fruits are small, red, fleshy drupes, in diameter.
|
|
The daggertooth (Anotopterus pharao, meaning "without fins on its back, of the Pharaoh") is a species of daggertooth. Its distribution includes the North Atlantic Ocean and west of Africa. The record size for this species is 96 cm and was hermaphroditic. Daggertooths are occasionally found dead in bottom trawls used for firefly squid or shrimp.
|
|
Reproduction in Bipalium may be asexual or sexual and all species are hermaphroditic. B. adventitium reproduces sexually and creates egg capsules, which hatch around 3 weeks post-deposition. The egg capsules have a tough exterior and generally contain multiple juveniles. B. kewense have rarely been observed using egg capsules as a primary method of reproduction.

Kew Bulletin 61: 205-214. Pineda is unique among Salicaceae in that the species have 4-5 sepals and petals, hermaphroditic flowers, receptacular disk glands (=nectaries), and outer filamentous staminodes. It is one of few genera of Salicaceae that occur at high elevations. Formerly placed in the heterogeneous family Flacourtiaceae,Sleumer, H.O. 1980. Flacourtiaceae.

|
The mucous gland is sac-like with short cilia. It shows the same histological staining properties as the distal membrane gland. The distal part of the mucous gland extends to the right side of the body wall where the hermaphroditic duct divides into the vas deferens and the oviduct. The oviduct widens to a cavity.
|
|
Solanum aviculare is an upright shrub that can grow up to tall. The leaves are, long, lobed or entire, with any lobes being long. Its hermaphroditic (having both male and female organs) flowers are white, mauve to blue-violet, wide, and are followed by berries wide that are poisonous while green, but edible once orange.
|
|
Pseudanthias bimaculatus do well when kept in an aquarium over 70 gallons. It is a deep water species that seems to do well when several hiding places are made available. It is considered a moderately difficult fish to care for and reef compatible. Like other anthias species, Pseudanthias bimaculatus share the trait of being hermaphroditic.
|
|
The two species of the genus are woody mangrove shrubs or small trees that grow up to 2 to 3 m tall. The deciduous species have leafy stems with leathery leaves arranged alternately or spirally. The leaf margins are entire and have parallel veins. The hermaphroditic flowers are pollinated by Hymenoptera, Lepidoptera, and Diptera.
|
|
Sea hares are mostly rather large, bulky creatures when adults. Juveniles are mainly unobserved on the shoreline. The biggest species, Aplysia vaccaria, can reach a length of and a weight of and is arguably the largest gastropod species. Sea hares have soft bodies with an internal shell, and like all opistobranch molluscs, they are hermaphroditic.
|
|
Most flowering plants are hermaphroditic but approximately 6% of species have separate males and females (dioecy). Males and females in insect-pollinated species generally look similar to one another because plants provide rewards (e.g. nectar) that encourage pollinators to visit another similar flower, completing pollination. Catasetum orchids are one interesting exception to this rule.
|
|
It is hermaphroditic, with both partners usually becoming fertilized during mating. The snail lays its eggs in moist conditions, and may retain its eggs until rain falls. The eggs have calcite crystals in their capsules, sometimes enough to form a shell around the egg. The snail consumes plant and fungal matter in the soil.
|
|
These hairs, along with the more or less oblong form of the inflorescence, are the inspiration for the common name. Pollination is carried out by bees, or via autogamy, since the plant is hermaphroditic, and the flowering season is from mid-spring to late summer. The fruit is a small pod containing a single seed.
|
|
Like all monogeneans, D. nezumiae has no intermediate host and is ectoparasitic. It is hermaphroditic, with the male reproductive organs becoming functional prior to the female organs. Filamented egg development leads to a highly ciliated larval stage known as the oncomiracidium that contains several posterior hooks, and is responsible for host to host transmission.
|
|
Mazus miquelii spreads rapidly by producing significant amounts of slender stolons which root at the nodes. The leaves are undivided and teethed along the margins. The blue or purple flowers are bilateral and have 5 petals, which emerge during the months of June to August. This species is hermaphroditic and is pollinated by insects.
|
|
The petals are "nailed", meaning they have a long handle ("nail") and a "plate". The nails of the petals are two to three times longer than the calyx. These plants are hermaphroditic and entomophilous, and their flowering period extends from April through July. Their legumes (seed pods) are oblong-cylindrical and long, with three to twelve segments.
|
|
The flowers grow solitary or are aggregated in terminal cymes, with free sepals and petals. Except for members of the genus Clematoclethra which have 10 stamens, the stamens are numerous and originally attached at the back. They invert just before the flower starts expanding, so their bases become apical. The plants may be dioecious, monoecious, or hermaphroditic.
|
|
It is found in moist woods. It is long-lived perennial, biennial, or annual with hermaphroditic flowers which are protandrous and self-fertile. The numerous fleshy stems form a rosette and the leaves are linear, lanceolate, or deltate. The flowers are 8–20 mm diameter, with five white, candy-striped, or pink petals, flowering is between February and August.
|
|
Further conflicts arise because a hermaphroditic individual may not necessarily use received sperm; it may use another partner's, or self-fertilise. According to risk-averse models, when this is the case, it would be more prudent for an individual to invest in eggs.Leonard JL. Modern Portfolio Theory and the prudent hermaphrodite. Invertebrate Reproduction & Development. 1999;36(1-3):129-35.
|
|
It is threatened by the degradation and destruction of its habitat. It is a federally listed endangered species of the United States. This plant is a subshrub growing up to a meter tall. It is the only hermaphroditic species among genus Schiedea; it is likely the plant's ancestors were gynodioecious, with some all-female flowers and the others bisexual.
|
|
They are hermaphroditic and scentless, have six upright tepals, the outer are slightly narrower than the inner ones. The flowers can reach 4–6 centimeters in length and are bright yellow-orange with reddish-brown dots. The stamens are erect, about half as long as the tepals, with red anthers. The style is orange, of height.
|
|
Echinacea purpurea is an herbaceous perennial up to tall by wide at maturity. Depending on the climate, it blooms throughout summer into autumn. Its cone-shaped flowering heads are usually, but not always, purple in the wild. Its individual flowers (florets) within the flower head are hermaphroditic, having both male and female organs in each flower.
|
|
Polyscias aemiliguineae is a species of plant in the family Araliaceae. It is endemic to Réunion. It is a shrub or tree, evergreen, hermaphroditic, andromonoecious or dioecious, unarmed, often glabrous, some with sharply aromatic herbage . Leaves 1-5-pinnately compound, margins entire to crenate or serrate; stipules sometimes intrapetiolar and adnate to inside of petiole or absent.
|
|
The flowers are perfect (hermaphroditic) and insect-pollinated, with fivefold symmetry. The ovary is divided into locules that are in turn divided by "false septa" (the latter distinguish Tribulus from other members of its family). Some species are cultivated as ornamental plants in warm regions. Some, notably T. cistoides, T. longipetalus, T. terrestris, and T. zeyheri, are considered weeds.
|
|
Two species are sold as fish bait. In most species the sexes are separate, but all the freshwater species are hermaphroditic. Nemerteans often have numerous temporary gonads (ovaries or testes), and build temporary gonoducts (ducts from which the ova or sperm are emitted), one per gonad, when the ova and sperm are ready. The eggs are generally fertilised externally.
|
|
Adults are hermaphroditic. The reproductive organ include a single ovary and a single testis. As in all diplectanids, the ovary (or germarium) is anterior to the testis and loops around the right intestinal caecum. Species of Pseudorhabdosynochus are characterized by a sclerotized male copulatory organ, or "quadriloculate organ", which has the shape of a bean with four internal chambers.
|
|
Such mollusks are hermaphroditic. Slugs most often function as decomposers but are also often omnivores. Arion ater is one such slug, decomposing organic matter, preying on other organisms, and consuming vegetative matter including agricultural crops. Native to Europe, the black slug is an invasive species in Australia, Canada (British Columbia, Newfoundland, Quebec), and the United States (Pacific Northwest).

Livy 27.11 (using the term androgynus); Rosenberger, "Republican nobiles," p. 297. Other rituals followed. A hermaphrodite found in 133 BC was drowned in the local river; committing the hermaphroditic person to the element of water seems to have been the prescribed way to repair the perceived violation of the natural order.Julius Obsequens 27a (androgynus); Rosenberger, "Republican nobiles," p. 298.

The English term for the tree is not believed to come from the word "old", but from the Anglo Saxon æld, meaning fire, because the hollow stems of the branches were used as bellows to blow air into a fire. The hermaphroditic flowers have five stamens,Parnell, J. and Curtis, T. 2012. Webb's An Irish Flora. Cork University Press.
|
|
The numerous flowers are located in the axils of small, membranous bracts. The hermaphroditic flowers are triple. The six identically shaped bracts are one-third to one-half their length and deformed tubular, bell-shaped or funnel-shaped in form. The color of the bracts ranges from white to cream to brown or more rarely from blue to purple.

|
Macrostomum is a genus of flatworm with a worldwide distribution, with over a hundred species described to date. These hermaphroditic, free-living flatworms are usually small in size, with large species reaching up to 5 mm in body length (e.g. Macrostomum tuba). They are usually transparent, and the smaller species appear rather round in cross-section than dorsoventrally flattened.
|
|
Like all pulmonate land snails, ambersnails are hermaphroditic, having both male and female reproductive systems, and are believed to be capable of self-fertilization. In the wild they live for between 12 and 15 months. Young snails enter dormancy between October and November, becoming active again in March and April. Mature snails reproduce in the summer months.
|
|
Illithids are hermaphroditic creatures who each spawn a mass of larvae two or three times in their life. The larvae resemble miniature illithid heads or four-tentacled tadpoles. Larvae are left to develop in the pool of the Elder Brain. The ones that survive after 10 years are inserted into the brain of a sapient creature.
|
|
Clonorchiasis sinensis is a trematode (fluke) which is part of the phylum Platyhelminthes. It is a hermaphroditic fluke that requires two intermediate hosts. The parasitic worm is as long as 10 to 25mm and lives in the bile ducts of the liver. The eggs of the worms are passed through fecal matter which are then ingested by mollusks.
|
|
Fragment released from the posterior end of an adult worm. All species of Bipalium are hermaphroditic, but Bipalium kewense has rarely been observed using sexual reproduction as a primary means of reproduction. Asexual fragmentation is the primary means of reproduction in B. kewense in temperate regions. Long specimens usually release body fragments at the posterior end by transverse fission.
|
|
It is rarely found in the intertidal, and is more likely to be found in the subtidal to 75 ft. Like most nudibranchs, Doris odhneri is hermaphroditic and mates with the right sides of the body together. Elegant ribbon-like egg masses are laid and attached to hard substrates.Hildering, J. & Miller, G., 2007 (Jul 27) Doris odhneri eggs?.
|
|
Its leaves have a pleasant texture and taste good served raw or cooked, and because of this, it is also known as wild spinach. It is a large perennial plant which grows up to , and flowers in the summer. Its flowers are hermaphroditic, and wind-pollinated. It requires moist, well- drained soils, and does not tolerate shade.
|
|
The hamuli are attached to an opistohaptor located on the dorsal side the flatworm, which is used to latch onto guppies. Attachment to the fish allows G. turnbulli to feed on the gills using its prohaptor, which is located on the anterior end. These parasites are hermaphroditic and viviparous, with a fully grown embryo existing in the utero.
|
|
Darker brown or red rays may mark the shell, creating darker areas at the margin. The shell's shape and structure also show much variation, hence its many synonyms; it has been described as "very similar to Pinctada margaritifera", and has been misidentified on occasion as P. margaritifera. P. radiata is hermaphroditic, with reproductive maturity being influenced by temperature.
|
|
Connections have been proposed between the 1st century figure of Tuisto and the hermaphroditic primeval being Ymir in later Norse mythology, attested in 13th century sources, based upon etymological and functional similarity.Simek (1995:432). Meyer (1907) sees the connection as so strong, that he considers the two to be identical.Meyer (1907): referenced in North (1997:269).

Pollination Bird cherries (drupes) A bird-cherry tree in full bloom The flowers are hermaphroditic and pollinated by bees and flies. The fruit is readily eaten by birds, which do not taste astringency as unpleasant. Bird- cherry ermine moth (Yponomeuta evonymella) uses bird-cherry as its host plant, and the larvae can eat single trees leafless.
|
|
The plant is native to western Europe. It reaches about tall and wide, bearing frilly leaves and hermaphroditic flowers; it is pollinated by insects and self-fertile. The small, rounded taproot is edible raw or cooked, and said to taste like sweet chestnuts. The leaf can be used as an herb or garnish similar to parsley.
|
|
Their function may be to increase the population of the parasite to keep up with the growth of the host. Rhombogens contain hermaphroditic gonads developed within the axial cell. These gonads, more correctly termed infusorigens, self-fertilise to produce infusoriform larvae. These larvae possess a very distinctive morphology, swimming about with ciliated rings that resemble headlights.
|
|
The diet of the snail is not well known, but it probably consumes microphytes, various microscopic algae. Like all other pulmonates, this snail is hermaphroditic, and may fertilize itself or mate with other individuals. Its reproductive habits are poorly known, but they may be similar to those of other river limpets.Geraerts, W. P. M. and J. Joosse.
|
|
The Lathyrus nevadensis plant is a trailer or weak climber vine, supported by tendrils, growing to 1.0 m-3 feet tall. The leaves are pinnate, with 4 to 10 leaflets and a straight, unbranched tendrils at the apex of the petiole. Its flowers are hermaphroditic, pollinated by bees. The plant can also spread vegetatively from creeping rhizomes.
|
|
There are extremely rare cases of fertility in "truly hermaphroditic" humans. These individuals typically have functional ovarian tissue, but underdeveloped testes that are unable to engage in spermatogenesis. As a result, these individuals are fertile, but not auto-fertile. There is evidence that 50% of individuals with ovotestes can go through ovulation but spermatogenesis is rare.
|
|
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the superfamily Coccoidea. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes.
|
|
A hermaphroditic hexapod from Alpha Centauri which, being effectively genderless, is referred to as "it" as opposed to "he" or "she". It is tall, green, has one large blue eye, six arms, and a high-pitched voice; it wears a long yellow cape and walks with a nervous gait. It is prone to cowardice and hysterics.
|
|
The flowers are hermaphroditic, and pollination is by insects. The fruits are ockery achenes, rod-shaped and with light ribs. They have a length of 10-17mm and a width of 1-3mm without counting the beak (with beak up to 55mm in length). When going to fruit, a ball of fluff gives the plant its name "goatsbeard".
|
|
Over 3,000 greenish-white flowers occur in male panicles, each with five to seven anthers and a nonfunctional ovary. Male flowers have yellow nectaries and five to seven stamens. About 500 greenish-yellow flowers occur in each hermaphroditic panicle. Each flower has six anthers, usually a bilobed stigma, and one ovule in each of its two sections (locules).
|
|
In Hindu India, there also exists different concepts of what is socially accepted when gender is in question. When compared to the native North Americans, the gender system is essentially binary, but the ideas themselves are quite different from Western thoughts. These ideas often come from religious contexts. Some Hindu origin myths feature androgynous or hermaphroditic ancestors.
|
|
Allogamy or cross-fertilization is the fertilization of an ovum from one individual with the spermatozoa of another. By contrast, autogamy is the term used for self-fertilization. In humans, the fertilization event is an instance of allogamy. Self-fertilization occurs in hermaphroditic organisms where the two gametes fused in fertilization come from the same individual.
|
|
Hydra are typically hermaphroditic or gonochoric. Uniquely to Hydra, the medusa stage is absent and only the polyps will reproduce sexually and asexually. H. viridissima will reproduce sexually when temperatures have warmed to at least 20 °C, typically this falls between May and June. Larger species will produce both ovaries and testes, while smaller individuals only develop testicles.
|
|
Gynodioecy occurs as a result of a genetic mutation that inhibits a hermaphroditic plant from producing pollen, while keeping the female reproductive parts intact. Gynodioecy is extremely rare, with fewer than 1% of angiosperm species exhibiting the breeding system. Some notable species that exhibit a gynodioecious mating system include Beta vulgaris (wild beet), Lobelia siphilitica, Silene, and Lamiaceae.

Connectors in which non- hermaphroditic contacts are arranged in a hermaphroditic arrangement (such as bullet connectors used in low end solar equipment) can be electrically incompatible (reverse polarity damages equipment) and non-hermaphroditic connectors can be mechanically incompatible with each other (won't mate). Many pieces of amateur radio equipment run on 12-volt DC automotive voltage, which is also called 13.8-volt DC. The voltage delivered by a lead–acid battery with six-cells used as an automotive battery will vary depending on various electrical loads in a vehicle. Without loads the battery will float from 11.7 to 12.8 volts, and while charging from an alternator the voltage will increase to 13.8–14.4 volts DC. For use in amateur radio, the community has adopted a standard color code, polarity, and specific physical arrangement for assembling pairs of Powerpole connectors. One red and one black powerpole housing can be physically arranged in 4 topologically different mechanical orientations (red left, red right, red top, red bottom - when viewed from contact side with tongue up), 2 of which are mechanically incompatible (connectors won't mate with ARES) and 1 is electrically incompatible (will mate but reverse polarity) with the ARES standard; there are also additional unusual configurations in which one housing is rotated 90 degrees.
|
|
The inflorescences are bracteate racemes or cymes. The flowers are hermaphroditic (bisexual), rarely unisexual (androdioecious), actinomorphic (rarely zygomorphic). The perianth is placed on a hypanthium that may be free or may be partly fused with the ovary (which is then semi-inferior). There are usually five sepals, but there may be three to ten, fused with the hypanthium, occasionally petaloid.
|
|
Triops cancriformis has a very fast life cycle, and individuals become mature in about two weeks after hatching. Their populations can be gonochoric, hermaphroditic or androdioecious. The latter is a very rare reproductive mode in animals, in which populations are made of hermaphrodites, with a small proportion of males. Due to this lack of males, early researchers thought Triops were parthenogenetic.
|
|
Gladiolus palustris reaches on average of height. The stem is erect, glabrous and unbranched, the bulbus is spherical with cross-linked fibers at the top. The leaves are shorter than the stem, simple, with a parallel venation, sword- shaped, long. The inflorescence is composed of three to six hermaphroditic flowers, trifoliate, with a rosy violet or magenta perigonium, about long.
|
|
Hermaphrodites have both male and female reproductive parts. The male and female system act as separate units until the egg and sperm are ready to fuse together. The fusion of egg and sperm takes place in the uterus of the female system. Hermaphrodites also have a hermaphroditic duct, which helps change the sex of the gastropod during certain times of the year.
|
|
Indoplanorbis exustus is a hermaphroditic invasive snail species with high fecundity. Within one year of introduction the snail is able to colonize habitats with well established populations of other pulmonate and prosobranch snails. The snail requires a water temperature in excess of 15 °C for maturation. At the optimum temperature of 30 °C each snail can lay up to 800 eggs.
|
|
The young shoots are reddish bronze and finely hairy. The flowers are hermaphroditic, small and inconspicuous, about 4 mm, greenish white, gathered in hairy racemes. The fruits are represented by the typical two-winged samaras, about 2.5 cm long, wind dispersed. It has been introduced for its wood and it is sometimes cultivated in large gardens for its evergreen foliage.
|
|
Like garden snails, Mertensia is hermaphroditic, reproducing sexually and occasionally asexually. Eggs and sperm are ejected into the water and from the fertilized eggs ovoid larvae develop. The planktonic larvae of this species are long while adults grow up to . The genus Mertensia commemorates the German naturalist Karl Heinrich Mertens aka Andrei Karlovich Mertens (17 May 1796 – 18 September 1830).
|
|
Close-up on purple-reddish blooms and blue flowers Lithospermum purpurocaerula is a bushy plant that reaches on average of height, with a maximum of . The stem is hairy, erect and unbranched. Leaves are dark green and lanceolate to narrow elliptic, with a prominent midrib on the underside. Flowers are hermaphroditic, funnel-shaped, long and of diameter, clustered in a racemose inflorescence.
|
|
The flowers are hermaphroditic and subterminal, in panicles that are 3 cm long. The fruits are globose, 6–7 mm across, and are attached on a thickened pedicel 2.5–3 cm long. Flowering occurs usually in February with fruit maturing in October. S. randaiense is found in broad- leaved forests from 900 to 2,400 m throughout the island of Taiwan.
|
|
G. antipoda is an upright or spreading shrub that grows to high. The leaves are long, and are leathery, shiny, with small serrations. G. antipoda flowers around November, followed by white to red berries in late summer and autumn. Unlike some other Gaultheria species that exhibit gynodioecy, G. antipoda is a hermaphroditic species (the individuals produce both pollen and seeds).
|
|
The leaves are small and green with serrated edges. Z.abelicea produces perfect hermaphroditic flowers which are small and scented, and pollination is therefore thought to be achieved by insects. This species is capable of suckering, a form of reproduction where new shoots arise from an existing root system rather than from a seed. Natural regeneration by seed is rarely seen.

Then she said "Abracadabra, hey Presto" and switched on the lights. She then quickly tossed her top hat into a crowd of ten thousand people. But Zoe had not gotten universal admiration when she first sang the song in Strike a New Note at the Prince of Wales Theatre in 1943. J B Priestley disapproved of her “strange, hermaphroditic garb”.
|
|
Echinoderms become sexually mature after approximately two to three years, depending on the species and the environmental conditions. They are nearly all gonochoric, though a few species are hermaphroditic. The eggs and sperm cells are typically released into open water, where fertilization takes place. The release of sperm and eggs is synchronised in some species, usually with regard to the lunar cycle.
|
|
It has fragile, woody branchlets that drop off in autumn along with the small, scale- like leaves that cover them. The leaf-shape is an adaption over time to exceedingly dry conditions. The pink flowers are tiny, hermaphroditic, and are borne on narrow, feather-like spikes. They frequently bloom earlier than the leaves, first in May, and sometimes a second time in August.

The Orphic Egg in the ancient Greek Orphic tradition is the cosmic egg from which hatched the primordial hermaphroditic deity Phanes/Protogonus (variously equated also with Zeus, Pan, Metis, Eros, Erikepaios and Bromius) who in turn created the other gods.West, M. L. (1983) The Orphic Poems. Oxford:Oxford University Press. p. 205 The egg is often depicted with a serpent wound around it.
|
|
The flowers are fragrant and hermaphroditic, surrounded by five unequal, thinly veined, yellowish-white petals. The flowers are about 1.0–1.5 cm (1/2") long and 2.0 cm (3/4") broad. They grow on slender, hairy stalks in spreading or drooping flower clusters which have a length of 10–25 cm. Flowering begins within the first six months after planting.
|
|
The hermaphroditic flowers are bilaterally symmetrical and grow either in racemes or spikes or singly at the apex of the slender stem. The tubular calyx is formed by 2–5 united sepals. There are five united, bilabiate petals forming the corolla and they may be yellowish, brownish, purplish, or white. The upper lip is two-lobed, the lower lip is three-lobed.
|
|
The upper leaves are smaller, lanceolate and sessile, almost embracing the stem. The flowers are arranged in a racemose inflorescence of extremely long-lasting blooms. These attractive bell-shaped flowers are short-stalked, large and hermaphroditic, with different shades of violet-blue or rarely white. The corolla has five fused petals with lightly bent lobes (known as a coronate flower type).
|
|
Inflorescences display a short protogynous phase (female organs mature first) and the majority are simultaneously hermaphroditic (bi- sexual). Most species of Acacia are at least partially self-incompatible but this is not known with purple-wood wattle. The fruits are orange, woody arils and may remain on the parent for several years after splitting open. Fruit production is very rare.
|
|
Breeding takes place in winter at an optimal temperature of . S. balanoides is hermaphroditic, but cannot fertilise itself. Gametes are transferred with a penis which may be up to long; barnacles that are further apart than about are therefore unable to reproduce together. One barnacle may inseminate another up to eight times, and up to six concurrent penetrations may occur.
|
|
The fish are simultaneous hermaphrodites, meaning they have both male and female reproductive parts at the same time. Unlike other hermaphroditic fishes, A. ferox has two distinct testicular lobes that are independent from the ovarian region. This species also an absence of a pair of diverticulae in the female reproductive section, which in other hermaphrodites is used for spermatophore uptake.
|
|
Helicina orbiculata, also known as Helicina (Oligyra) orbiculata and as Oligyra orbiculata, is a species of land snail with an operculum, a terrestrial gastropod mollusk in the family Helicinidae. They are one of few land snails to have eyes at the base of their tentacles. This may suggest Helicina Orbiculata individuals are separate male and female, as opposed to the usual hermaphroditic snail.

Old Gregg is portrayed by Noel Fielding. He was created for "The Legend of Old Gregg", a 2005 episode of the TV series. He later went on to appear in the 2006 stage show, The Mighty Boosh. Old Gregg is a hermaphroditic merman who occasionally refers to his vagina, which emits a blinding light that "makes you feel tingly", as his "mangina".
|
|
There may be male and female flowers on different inflorescences, they may alternate along the same branches, in some cases the female flowers are proximal while the male's are distal, some are hermaphroditic and others are simply, but rarely, dioecious. Developing from one carpel, the fruit matures to red in color, may be ellipsoidal, laterally flattened or disciform, and contains one seed.

The first proglottid stage is the immature stage, characterized by functional reproductive organs. The immature stage is the most anterior proglottid, and consists of anywhere between 200 and 300 proglottids. The mature proglottid is located medially to the other proglottids, and is reproductively functional and hermaphroditic. The most posterior proglottid is the gravid stage, and it is packed with eggs.

Five of these use an XY system, and one (Ginkgo biloba) uses a WZ system. Some gymnosperms, such as Johann’s Pine (Pinus johannis), have homomorphic sex chromosomes that are almost indistinguishable through karyotyping. Angiosperms Cosexual angiosperms with either monoecious or hermaphroditic flowers do not have sex chromosomes. Angiosperms with separate sexes (dioecious) may use sex chromosomes or environmental flowers for sex determination.

Serranus baldwini is a marine reef- associated species, living in rocky and weedy areas at a depth of 1 – 80 m. It shows a strong association with beds of turtle grass (Thalassia testudinum), althpugh juveniles use the empty shells of conches to hide in. It is a territorial species which feeds on shrimps and smaller fishes. It is synchronously hermaphroditic, i.e.

Auriculella is a genus of air-breathing tropical land snails, terrestrial pulmonate gastropod mollusks in the family Achatinellidae. They are endemic to Hawaii (United States) and several species are extinct. They are oviparous (egg laying) and hermaphroditic. Among achatinellid snails, they are unique in the fact that they are not restricted to living on plants endemic to the Hawaiian islands.

Caryocar nuciferum, the butter-nut of Guiana, is also known as pekea-nut, or – like all other species of Caryocar with edible nuts – "souari-nut" or "sawarri-nut". It is a fruit tree native to northern Brazil, Colombia, Costa Rica, Guyana, Panama, and Venezuela. This colourful tree grows up to 35 m, in humid forests. Flowers are hermaphroditic and in small clusters.

In some species, such as sequentially hermaphroditic clownfish, changes in social environment can lead to sexual differentiation or sex reversal, i.e. differentiation in the opposite direction. In clownfish, females are larger than males, and in social groups, there is typically one large female, multiple smaller males, and undifferentiated juveniles. If the female is removed from the group, the largest male changes sex, i.e.

Zigzag scallops are a hermaphroditic species which reproduces through broadcast spawning. They are known as “dribble spawners” in Bermuda because, while the local population spawns around the same general times of year, no synchronous mass spawning events occur. Instead, individuals spawn at slightly different times within the same season. Spawning usually occurs twice annually, although exact spawning periods vary by region.

|
As with other earthworm species, E. fetida is hermaphroditic, and uniparental reproduction is possible, even if usually the reproduction is between copulating individuals. The two worms join clitella, the large, lighter-colored bands which contain the worms' reproductive organs, and which are only prominent during the reproduction process. The two worms exchange sperm. Both worms then secrete cocoons which contain several eggs each.
|
|
Pheretima is a genus of earthworms found mostly in New Guinea and parts of Southeast Asia. Species belonging to the genus Pheretima have a clitellum, which is a band of glandular tissue present on segments 14 to 16. Individuals are hermaphroditic and reproduction can be either sexual or parthenogenetic. Female genital pores lie on the ventral surface of segment 14.

In biology, gonochorism (Greek offspring + disperse) or unisexualism or gonochory describes the state of having just one of at least two distinct sexes in any one individual organism. The term is most often used with animals, in which the individual organisms are often gonochorous. Gonochory is less common in plants. For example, in flowering plants, individual flowers may be hermaphroditic (i.e.

Illustration of a male Males are rare in hermaphroditic species of Icerya. Males are haploid while females are diploid. Females have an ovitestis that is capable of producing both sperm and oocytes which fertilize internally to produce diploid offspring (females) through a form of hermaphroditism. The cells of the ovitestis are haploid and are derived from excess sperm during matings with males.

Most ramshorn snails are considered minor aquarium pests. They may arrive in a tank as egg bundles hidden in newly acquired plants. Although their red color may make them somewhat interesting aquarium subjects, their hermaphroditic ability to breed prolifically from any two specimens can make them troublesome. Absolute eradication is difficult, but their numbers can usually be kept to a moderate level.

Hippospongia communis sexually reproduces year round. The sponge is also hermaphroditic, meaning it has both male and female reproductive organs at the same time. It has been found that during its sexual reproduction, regardless of the location, the Hippospongia communis eggs will fertilize at the same time. The bath sponge reproduction times are all synced throughout different locations that the H. communis inhabit.

Only ray florets are female, others are male, hermaphroditic or entire sterile. Head involucres are campanulate to cylindric or attenuate. Floret corollas are usually yellow, but white in the ray florets of a few species (such as Solidago bicolor); they are typically hairless. Heads usually include between 2 and 35 disc florets, but in some species this may go up to 60.

|
Reproductive plants produce one to eight reproductive stalks. Each flowering stalk can display between 5 and more than one hundred bright purple, hermaphroditic, slightly protandrous flowers arranged in corimbous inflorescences. Flowering stalks are tall (circa 1 m tall) in E. baeticum bastetatum, and very short (around 20 cm tall) in Erysimum baeticum baeticum. Flowers produce minute amount of nectar in four nectaries.

175 . Since Nerthus in Tacitus' late-1st century Germania is an earth goddess, terra mater (mother earth), but her name is etymologically identical to his, the suggestion is that there was originally a hermaphroditic deity, or more likely that they were a married twin pair, parallel to Freyr and Freyja.Rudolf Simek, Dictionary of Northern Mythology, tr. Angela Hall, Cambridge / Rochester, New York: Brewer, 1993, repr.

Eggs are released immediately before oviposition. Unlike in land gastropod species where fertilization occurs in fertilization pockets, fertilization in freshwater species happens at the lower end of the hermaphroditic duct, near the junction. Sperm is deposited into the bursa copulatrix which opens up into the vagina. The ova then enter the albumen gland to get a nutrient dense mucus coating which serves to form the egg capsule.

Asphodelus albus from Mavrovo National Park, North Macedonia Capsules and seeds White asphodel grows to a height of . The plain stem is supported by fleshy, thickened roots (rhizomes). The leaves, which originate from the base of the stem, are gutter- shaped and glaucous (covered by a waxy coating), about wide and long. The white hermaphroditic flowers are funnel-shaped, of diameter, with six elongated petals.

The scolex bears an apical rounded rostellum, which is armed with 100 minute hooks, arranged in single row. This is surrounded by four suckers which are lined with 5-6 rows of spines. The most important diagnostic characters in comparison to other species are oval scolex and suckers, with relatively elongated neck. R. tetragona is strictly hermaphroditic having a complete reproductive system in itself.

Development of oogonial stem cells in C. elegans adult hermaphrodites The nematode Caenorhabditis elegans (C. elegans) are nematodes can have hermaphroditic or male reproductive capabilities. In males, only spermatogenesis occurs; hermaphrodites can produce spermatozoa until adulthood, when oogenesis takes over. All oogonial stem cells in C. elegans are derived from one distal-tip cell (DTC), which acts as a niche to ensure that germline proliferation continues.

Because of the sparse distribution and lack of light, finding a partner with which to breed is difficult, and many organisms are hermaphroditic. Because light is so scarce, fish often have larger than normal, tubular eyes with only rod cells. Their upward field of vision allows them to seek out the silhouette of possible prey. Prey fish however also have adaptations to cope with predation.

In 1969 two film versions were made. Fellini Satyricon, directed by Federico Fellini, was loosely based upon the book. The film is deliberately fragmented and surreal though the androgynous Giton (Max Born) gives the graphic picture of Petronius's character. Among the chief narrative changes Fellini makes to the Satyricon text is the addition of a hermaphroditic priestess, who does not exist in the Petronian version.

The species originated as a hybrid between two species, and is diploid, but not hermaphroditic. It can have triploid and tetraploid forms, including all- female forms that reproduce mainly through hybridogenesis. It is rare to find true parthenogenesis in fishes, where females produce female offspring with no input from males. All-female species include the Texas silverside, Menidia clarkhubbsi as well as a complex of Mexican mollies.

It is born male, becomes hermaphroditic at puberty, and reproduces by tossing clouds of sperm and eggs into the surrounding water. If it is alone, it will procreate by self-fertilization. Its blood is clear and can contain high concentrations of vanadium, which may be ten million times that found in surrounding seawater, although the source and function of this element's concentrations are unknown.

Additionally, Binmore (2005) has argued that some real-world situations can be described by the Centipede game. One example he presents is the exchange of goods between parties that distrust each other. Another example Binmore (2005) likens to the Centipede game is the mating behavior of a hermaphroditic sea bass which takes turns exchanging eggs to fertilize. In these cases, we find cooperation to be abundant.

Middlesex delves into the concept of identity, including how it is formed and how it is administered. The immigrant predicament is a metaphor and synecdoche for Calliope's hermaphroditic condition; Callie's paternal grandparents become Americanized through the amalgamation of the elements of heredity, cultural metamorphoses, and probability. Callie's maternal grandfather, Jimmy Zizmo, undergoes a rebirth when he transforms from a bootlegger into Fard Muhammad, a Muslim minister.

The leaves are arranged alternately on petioles. They are ovate, long by wide (rarely to by ). They have 6–10 pairs of prominently grooved and slightly downy veins and an entire margin. The flowers are small, in diameter, star-shaped with five greenish-white acute triangular petals, hermaphroditic, and insect-pollinated, flowering in May to June in clusters of two to ten in the leaf axils.

Commonly, many hermaphroditic species mutually inseminate, or trade sperm, rather than compete, Chelidonura sandrana as an example. The tiger flatworm, Maritigrella crozieri, also transfers sperm bilaterally. In many species that engage in bilateral insemination, sperm trading is conditional. If one partner "cheats", and does not transfer sperm, the other partner will either prematurely abandon the partner, or will engage in typical mating behavior without transferring sperm.

Though they are sexually hermaphroditic and cross-fertilization is the norm, self-fertilization sometimes occurs and makes possible the reproduction of a worm when it is the only individual in its host's gut.

The (usually pinnately compound) leaves are evergreen and lack stipules. They are alternate, rarely opposite. The plants are monoecious, the male flowers being in lateral panicles (several pairs of catkins on an inflorescence) and the female flowers born terminally either in a single spike or in a hermaphroditic panicle including several paired male catkins. Each flower has a wide bract, two bracteoles, and four sepals.

Although it generally flowers in April–August, A. brachystachya does flower irregularly depending on weather and climatic conditions. These flowers are hermaphroditic and grow after heavy rainfall at any time of year. Despite the potential year round flowering, reproduction does not always follow. Mature pods are usually only developed when summer rain is the cause of flowering followed by rain in the subsequent winter.

The endemic Dombeyoideae from the Mascarenes are polyphyletic and split into nine clades. Trochetia appears monophyletic and more closely related to Eriolaena and Helmiopsis than to Dombeya. All Dombeya taxa are included in a clade together with Ruizia and Astiria, this means that Dombeya is paraphyletic. In terms of breeding systems the Malagasy Dombeyoideae are hermaphroditic, whereas those of the Mascarenes are considered dioecious.

The rushes of the genus Juncus have flat, hairless leaves or cylindrical leaves. The leaves of the wood-rushes of the genus Luzula are always flat and bear long white hairs. The plants are hermaphroditic or, rarely, dioecious. The small flowers are arranged in inflorescences of loose cymes, but also in rather dense heads or corymbs at the top of the stem or at its side.

Ampelocissus is a genus of Vitaceae having 90 or more species found variously in tropical Africa, Asia, Central America, and Oceania. The type species, A. latifolia, was originally treated under its basionym, Vitis latifolia, and was collected from the Indian subcontinent. Species of Ampelocissus are herbaceous or woody, hermaphroditic or polygamo-dioecious flowering plants with tendrils for climbing. Fruits are grape-like berries having 1-4 seeds.
|
|
Mating may also lead to external fertilization, as seen in amphibians, fishes and plants. For the majority of species, mating is between two individuals of opposite sexes. However, for some hermaphroditic species, copulation is not required because the parent organism is capable of self-fertilization (autogamy); for example, banana slugs. The term mating is also applied to related processes in bacteria, archaea and viruses.

The lid over the entrance, the operculum, prevents rainwater entering the pitcher and thus diluting the digestive enzymes inside. Insects trapped in this digestive fluid are consumed by the plant. The operculum has translucent cells which confuse its insect prey as they appear to be patches of sky. The inflorescence is groupings of small, hermaphroditic, six-parted, regular flowers, which are creamy, or whitish.

Jacob Bryant's Orphic Egg (1774) The Orphic Egg in the Ancient Greek Orphic tradition is the cosmic egg from which hatched the primordial hermaphroditic deity Phanes/Protogonus (variously equated also with Zeus, Pan, Metis, Eros, Erikepaios and Bromius) who in turn created the other gods.West, M. L. (1983) The Orphic Poems. Oxford:Oxford University Press. p. 205 The egg is often depicted with a serpent wound about it.

Detail of foliage - showing new and old leaves It produces dense, elegant whorls of leaves, which are thick, leathery, elliptical and covered in reddish brown fur when young (especially in winter). Even adult leaves can be a furry reddish-brown on the underside. It produces tiny hermaphroditic flowers - packed along its stems - and black berries which exude a white latex. Its wood is unusually strong and heavy.

Speleonectes atlantida is approximately long. Like most other remipedes, the species lacks eyes and is hermaphroditic. Adapted to life in caves, the long antennae sprouting from its head and the presence of sensory hairs along its body allow the crustacean to feel its way along the dark tunnel. The species is equipped with venom-injecting fangs, a feature unique to class Remipedia among crustaceans.

Diphasic sex expression is not limited just to plants, as many species of fish also alter their sex. About two percent of known fish species display sequential hermaphroditic changes. For example, juvenile Caribbean parrot fish are female when young and may transition to male as they age. Many of these terminal phase males then go on to fulfill varying roles such as female and territorial protection.

Austroderia richardii usually flower around spring and early summer (September to November) though they always retain their plumes. It implements a stage of fruiting around the October and March months. All Austroderia species in New Zealand, including introduced ones, have been proven to be gynodioecious. Being gynodioecious means they are involved in a dimorphic breeding system in which male-sterile individuals coexist with hermaphroditic individuals in populations.

Fertile flowers have a gamosepalous calyx beneath their corolla and display five distinctive lobes. Each fertile flower has ten androgynous stamen evenly joined at their base, with a single style and several minuscule stigma. Though typically hermaphroditic and containing a single ovary, some flowers are functionally male and lack both ovaries and styles. Some flowers can produce nectar in large quantities that adheres to the styles.

The development of monoecious and gonochoristic species represents a transition from broadcast fertilization to localized and internal fertilization. The Broad-barred goby is capable of bi-directional sex change. Simultaneous hermaphrodism exists in species with pre-Cambrian roots, and several families of organisms have shifted between hermaprodism and gonochoism over their evolutionary history. There are sequentially hermaphroditic species, such as the goby, which show bidirectional sex changing.

Drawing of reproductive system of Fiona pinnata. Reproductive system: There are two genital openings on the right side of the head behind the oral tentacle: the opening for the penis and for the (hermaphroditic) genital pore. The reproductive system and the mucous gland is the same as in the genus Aeolidia. The only difference is that there is a distinct vas deferens in Fiona pinnata.

The relationship with other molluscs, however, is apparent from some features of the digestive system; aplacophorans possess both a radula and a style. A variety of radular forms and functions exist. Solenogasters are hermaphroditic, but caudofoveates have two sexes, and reproduce by external fertilization. During development, the mantle cavity of the larva curls up and closes, creating the worm-like form of the adult.

It has been shown that though darts may aid in mating, they do not necessarily ensure mating success. However, love darts do in fact aid in mating success. Hermaphroditic snails will selectively take on a female or male role. Snails transmitted darts into these females so that they would store more sperm (about twice as much) compared to males who were not as successful.
|
|
On the contrary, non-hermaphroditic plants are self- incompatible. Research has shown that a species can be either gynodioecious or self-incompatible, but very rarely is there a co-occurrence between the two. Therefore, gynodioecy and self-incompatibility tend to prevent each other’s maintenance. Self-incompatibility of plants helps maintain androdioecy in plants, since males are in competition with only hermaphrodites to sire ovules.

Detail of the florets and bracts of a flowering orange tulip ginger Glossy, overlapping bracts form a terminal inflorescence, that is spike-shaped to ovoid. The bracts are red to orange, usually becoming more orange at the apex, which curves outward. The inflorescence is quite variable in size, ranging from long and cm broad. During flowering, small, hermaphroditic yellow or orange tubular florets emerge among the bracts.

The lack of light requires creatures to have special adaptations to find food, avoid predators, and find mates. Most animals have very large eyes with retinas constructed mainly of rods, which increases sensitivity. Many animals have also developed large feelers to replace peripheral vision. To be able to reproduce, many of these fish have evolved to be hermaphroditic, eliminating the need to find a mate.

The shrub flowers from August to October and the hermaphroditic flowers are scarlet-red, tinged with purple. When fully open they turn dark purple and at night a sweet scent emanates from them. The fruits ripen from December to January and are erect capsules, about 25 mm long that open at the tip in two follicle-like portions. The numerous seed show reticulate wings of about 4 mm.

As a graduate student of Hokkaido University in Japan Yanagimachi studied fish (herring) fertilization and the sexual organization of rhizocephalans (parasitic barnacles). In fish, he discovered calcium-dependent, chemotactic movement of spermatozoa into the micropyle through which the fertilizing spermatozoon enters the egg. This was the first discovery of sperm chemotaxis in vertebrate animals. In rhizocephala, he found that adults are not hermaphroditic as generally thought, but bisexual.

However, alternative views state that the male role is preferred, as males benefit more from multiple matings than females do.Michiels NK, Raven-Yoo-Heufes A, Kleine Brockmann K. Sperm trading and sex roles in the hermaphroditic opisthobranch sea slug Navanax inermis: eager females or opportunistic males? Biological Journal of the Linnean Society. 2003;78(1):105-16. Neither strategy is evolutionarily stable, as both gender roles are required for successful reproduction.

Macmillan . The flowers are yellow (male) and greenish (female), about across, borne in large branched panicles up to long in spring; it is dioecious, with male and female flowers produced on separate trees. The fruit is a yellow to blue-black, reniform (kidney-shaped) drupe long, ripening in mid-autumn. Occasionally a male plant of T. fortunei, besides the usual spadices, produces a few other spadices carrying really hermaphroditic flowers.

They are radially or (rarely) laterally symmetric, and generally hermaphroditic. They have four or five petals and sepals, sometimes three, mostly separate, eight to ten stamen (five in Skimmia, many in Citrus), usually separate or in several groups. Usually a single stigma with 2 to 5 united carpels, sometimes ovaries separate but styles combined. The fruit of the Rutaceae are very variable: berries, drupes, hesperidia, samaras, capsules, and follicles all occur.

The sand grey mullet can spawn eggs from November to March, however, peak season is from January to March depending on the location they are living in. Their reproductive organs are different shapes and colors depending on the stage of development. As they grow older their reproductive organs become thinner and. Many ray-finned fish are known for being hermaphroditic but this is unknown about the sand grey mullet fish.

12 The Romans also had traditions that centered around ritual murder, but which they did not consider to be sacrifice. Such practices included burying unchaste Vestal Virgins alive and drowning hermaphroditic children. These were seen as reactions to extraordinary circumstances as opposed to being part of Roman tradition. Vestal Virgins who were accused of being unchaste were put to death, and a special chamber was built to bury them alive.

Larger species often break up when stimulated, and the fragments often grow into full individuals. Some species fragment routinely and even parts near the tail can grow full bodies. All reproduce sexually, and most species are gonochoric (the sexes are separate), but all the freshwater forms are hermaphroditic. Nemerteans often have numerous temporary gonads (ovaries or testes), forming a row down each side of the body in the mesenchyme.

In Greek mythology, Nana () was a daughter of the Phrygian river-god Sangarius, identified with the river Sakarya located in present-day Turkey. She became pregnant when an almond from an almond tree fell on her lap. The almond tree had sprung from the spot where the hermaphroditic Agdistis was castrated, becoming Cybele, the Mother of the Gods. Nana abandoned the baby boy, who was tended by a he-goat.

Greeneyes are generally deepwater fish, found from . They seem to prefer the continental slopes and shelves, possibly forming schools. Greeneyes are known to primarily feed on benthic invertebrates, as well as pelagic crustaceans such as decapods and mysids. Like many aulopiform fish, greeneyes are hermaphroditic; this is thought to be a great advantage in deep-sea habitats, where the chances of running into a compatible mate are uncertain.

The reproductive system of Pseudunela cornuta is simultaneous hermaphroditic. The anterior genitalia show a special androdiaulic condition: the vas deferens does not branch off in a proximal position as usual in androdiaulic nudibranch or acteonoidean species, but more distally, i.e. autosperm must pass through the nidamental glands. Nevertheless, this reproductive system is not strictly monaulic, because the internal vas deferens (for autosperm) is separated from the distal portion of the oviduct.

Polyscias flynnii is a tree up to 9 m tall. Leaves are pinnately compound, up to 60 cm long, with reddish-brown hairs on the underside but not on the upper side. Inflorescence is a panicle or umbel hanging from the axils of the leaves, with 10-15 flowers. Flowers are yellow-green, some hermaphroditic (both male and female) but others on the same plant staminate (male only).

The now-female Uumarnituq was also responsible for introducing war into the world via magic, in order to curb overpopulation. The goddess Sedna is an Inuit creator deity, with dominion of marine animals. She is depicted as gynandrous or hermaphroditic in some myths, and is served by two-spirit shamans. Other myths show Sedna as a bisexual or lesbian, living with her female partner at the bottom of the ocean.

Both hermaphrodite and monoecious species have the potential for self- pollination leading to self-fertilization unless there is a mechanism to avoid it. Eighty percent of all flowering plants are hermaphroditic, meaning they contain both sexes in the same flower, while 5 percent of plant species are monoecious. The remaining 15% would therefore be dioecious (each plant unisexual). Plants that self-pollinate include several types of orchids, and sunflowers.

The overwhelming majority of scleractinian taxa are hermaphroditic in their adult colonies. In temperate regions, the usual pattern is synchronized release of eggs and sperm into the water during brief spawning events, often related to the phases of the moon. In tropical regions, reproduction may occur throughout the year. In many cases, as in the genus Acropora, the eggs and sperm are released in buoyant bundles which rise to the surface.

Like all sea hares, the California sea hare is hermaphroditic, acting as male and female simultaneously during mating. Aplysia are known to form mating chains with up to 20 animals. The eggs are yellow-green, and change after 8 to 9 days into a brown color before larvae hatch. Mating is most prominent during the summer month following the rise of the water temperature to 17 degrees Celsius.

Epinephelus albomarginatus is targeted by both recreational and commercial fisheries. In South Africa the traditional commercial fishery uses hook and lines from vessels, while in Mozambqiue line fishing is also used with both handlines and rod and line being used. The catch is sold locally and is also exported to Europe. The slow growth, late maturity and protogynous hermaphroditic life history of this species make it vulnerable to overfishing.

In the majority of plant species, individual flowers have both functional carpels and stamens. Botanists describe these flowers as "perfect" or "bisexual", and the species as "hermaphroditic". In a minority of plant species, their flowers lack one or the other reproductive organ and are described as "imperfect" or "unisexual". If the individual plants of a species each have unisexual flowers of both sexes then the species is "monoecious".

Most species have separate male and female flowers, but a few have hermaphroditic flowers. Little is known about seed dispersal. However, tree shrews and other forest mammals eat the fruits and disperse the seeds. Rafflesia is the official state flower of Indonesia, where it is known as puspa langka (rare flower) or padma paksasa (giant flower), of Sabah state in Malaysia, and of Surat Thani Province in Thailand.

In B. Campbell (Ed.), Sexual selection and the descent of man, 1871–1971 (pp. 136–179). Chicago, IL: Aldine. In species where males take on more of the reproductive costs, such as sea horses and jacanas, the role is reversed, and the females are larger, more aggressive and more brightly coloured than the males. In hermaphroditic animals, the costs of parental care can be evenly distributed between the sexes, e.g. earthworms.

In polygamous species, flowers have been assessed as bisexual on the basis of morphology only. Pollen produced by apparently hermaphroditic flowers has, in a few cases, been found to be inaperturate, rendering the flower functionally female. Sepals 3 to 5, often unequal, sometimes accrescent. Petals 4 or 5, or rarely 3, 6, 7, or 8, often contort, free or fuzed at base only, sometimes reflexed over the sepals.

Pollination is an important step in the sexual reproduction of higher plants. Pollen is produced by the male flower or by the male organs of hermaphroditic flowers. Pollen does not move on its own and thus requires wind or animal pollinators to disperse the pollen to the stigma (botany) of the same or nearby flowers. However, pollinators are rather selective in determining the flowers they choose to pollinate.

Papaver setigerum reaches on average in height. The stem is erect and the leaves are simple, oblong, the lower ones are sessile, deeply lobed and toothed, the higher ones shortly pedunculated. The flowers at the apex of the stem are hermaphroditic, actinomorphic ("star shaped", "radial"), 4 to 10 cm in diameter. The corolla forms a cup with four pink-purple petals, with a dark purple blotch at the base.

The polyps of Porites astreoides feed mostly at night, extending their tentacles to catch zooplankton and bacteria. The coral also obtains an important part of its nutritional needs as a result of the photosynthesis performed by the zooxanthellae in sunlight. Some colonies of Porites astreoides are female while others are hermaphroditic. Sexual reproduction occurs with male gametes being released into the sea around the time of the new moon.

Morning glory vines spread their vegetation and flowers reproduce via mixed mating systems. Peanut plants utilize mixed mating systems, often with cleistogamous flowers. A mixed mating system (in plants), also known as “variable inbreeding” a characteristic of many hermaphroditic seed plants, where more than one means of mating is used. Mixed mating usually refers to the production of a mixture of self-fertilized (selfed) and outbred (outcrossed) seeds.

Hermaphroditic; Corella willmeriana breeds throughout the year. The eggs are fertilized in the atrial chamber, where they develop into the free-swimming tadpole stage before released. Swimming larvae remain juveniles for <2 days before anterior adhesive organs allow for attachment to substratum. This triggers metamorphism, which entails enlargement of pharynx for filter feeding; the notochord is sucked back into body and is no longer present in adult form.

Members of the family are small to large herbaceous plants with distichous leaves with basal sheaths that overlap to form a pseudostem. The plants are either self-supporting or epiphytic. Flowers are hermaphroditic, usually strongly zygomorphic, in determinate cymose inflorescences, and subtended by conspicuous, spirally arranged bracts. The perianth is composed of two whorls, a fused tubular calyx, and a tubular corolla with one lobe larger than the other two.
|
|
Inflorescence and Corolla Differences Inflorescences can be acted on by sexual selection in many ways, and commonly include arrangement, number, and size. For example, male inflorescence in plants often produce more flowers than females . Furthermore, pollen export and ultimately paternity, often increases with flower number, even for plants with hermaphroditic flowers. Retention of older flowers with no pollinator rewards can lead to increased pollinator visitation rate and increased pollen removal.
|
|
Individual species are cosexual (with several types of hermaphroditic conditions) or dioecious, and are either wind-pollinated (anemophilous) or self-pollinating (autogamous). Two predominantly apomictic species are also known. Flower-like reproductive units are composed of small collections of minute stamen- and/or pistil-like structures that may each represent very reduced individual flower, so that the reproductive units may be pseudanthia. The non-fleshy fruits are follicles or achenes.

Within Blavatsky's complex cosmology, which includes seven "Root Races", the "Third Root Race" occupied Lemuria. She describes them as about tall, sexually hermaphroditic, egg-laying, mentally undeveloped and spiritually more pure than the following "Root Races". Before the coming of the Lemurians, the second "Root Race" is said to have dwelled in Hyperborea. After the subsequent creation of mammals, Mme Blavatsky revealed to her readers, some Lemurians turned to bestiality.

The three standard sex symbols are the male symbol and the female symbol , and the hybrid symbol . They were first used to denote the effective sex of plants (i.e. sex of individual in a given crossbreed, since most plants are hermaphroditic) by Carl Linnaeus in 1751. The male and female symbols are still used in scientific publications to indicate the sex of an individual, for example of a patient.

This species is protandrous, which is to say that young animals are male and then become female later in life. In each population, there are males and females in approximately equal numbers, and 4-5% of the population is hermaphroditic. In some populations, the sex ration skews towards males for reasons that are not known. Females have been observed to produce between 40,000 to 6,000,000 eggs during the summer breeding season.

The most notable symbol of theistic Satanism. Seeking knowledge is seen by some theistic Satanists as being important to Satan, due to Satan being equated with the serpent in Genesis, which encouraged humans to partake of the fruit of the Tree of Knowledge of Good and Evil. Some perceive Satan as Éliphas Lévi's conception of Baphomet — a hermaphroditic bestower of knowledge (gnosis). Some Satanic groups, such as Luciferians, also seek to gain greater gnosis.

Snail farming is referred to as heliciculture, and includes the process of farming or raising land snails specifically for human consumption. Some commercial snail farms collect and process snail caviar, which is then jarred and marketed to consumers. Sometimes the snails are raised and kept in temperature, lighting and climate controlled conditions to encourage maximal reproduction, which produces the eggs. Since snails are hermaphroditic (having both male and female sexual organs), all can produce eggs.

Designed by visual effects artist Phil Tippett, Jabba the Hutt was inspired by the anatomy of several animal species. His body structure and reproductive processes were based on annelid worms, hairless animals that have no skeleton and are hermaphroditic. Jabba's head was modeled after that of a snake, complete with bulbous, slit-pupilled eyes and a mouth that opens wide enough to swallow large prey, even a humanoid. His skin was given moist, amphibian qualities.

The inflorescence consists of bunches of a few flowers which are either sessile or are borne on short stalks. The flower buds are ovoid and covered in a short tomentose pubescence. The individual flowers are greenish- yellow in colour, hermaphroditic with five petals in radial symmetry and are in diameter. The pedicel of the inflorescence is greyish in colour, downy and usually less than in length, although has been recorded in Zambia and Zimbabwe.

Lifecycle of Opisthorchis O. viverrini is a hermaphroditic liver fluke. Similar to C. sinensis and O. felineus, it requires three different hosts to complete its lifecycle. Freshwater snails are the first intermediate hosts in which asexual reproduction takes place, and freshwater fishes belonging to the family Cyprinidae) are second intermediate hosts in which larval development occurs. Fish–eating (piscivorous) mammals, including humans, dogs, and cats, act as definitive hosts, in which sexual reproduction occurs.

Drawing of a love dart of P. picta Polymita picta mainly feeds on lichen, moss and on fungal biofilms present on bark and leaves. The life cycle lasts about 15 months, with breeding time during the wet season (September- October). The snails become dormant in the dry season (December- beginning of May). Like most air- breathing land snails, Polymita picta has female and male reproductive organs (hermaphroditic), it is unable to self-fertilization.

These were expiated by the sacrifice of "greater victims". The minor prodigies were less warlike but equally unnatural; sheep became goats; a hen become a cock, and vice versa. The minor prodigies were duly expiated with "lesser victims". The discovery of a hermaphroditic four-year-old child was expiated by its drowningRosenberger, in Rüpke (ed), 295 - 8: the task fell to the haruspex, who set the child to drown in the sea.

Like other Scyphozoans, Chrysaora hysoscella undergo metamorphosis as the organism develops and experiences a polyp and then medusa form. Females release planular larvae which swim to find a suitable place to settle. The planulae attach to a benthic substrate and develop into a sessile polyp which releases immature medusae through asexual reproduction called strobilation. Chrysaora hysoscella function as a male upon maturity and then develop female gametes, meaning this organism is protandrously hermaphroditic.

The habit of this plant can be a small tree or a shrub up to 15 feet tall, and the flowers are hermaphroditic. These white trumpet shaped flowers can grow to about 6 inches long, and are followed by woody oval-shaped fruit 2–3 cm long with a dry appearance (Tucker 2010). The large leaves are dark green with a pinnate venation, and have an opposite arrangement on the plant stem.
|
|
The slender, high-climbing trunks are naturally clustering and can reach up to 45 m in length. The pinnate leaves range from 30 cm to 2.5 m on short, armed petioles; the rachis, leaf margins and cirri are also armed with spines. They are hermaphroditic, with both male and female reproductive organs present in each flower. The pale blooms are fragrant and produce a red to brown, scaly fruit, each containing one to three seeds.

Among sea anemones, sexual plasticity may occur. That is, asexually produced clones derived from a single founder individual can contain both male and female individuals (ramets). When eggs and sperm (gametes) are formed, they can produce zygotes derived from “selfing” (within the founding clone) or out-crossing, that then develop into swimming planula larvae. Polyps of a colony of Cnidaria The overwhelming majority of stony coral (Scleractinia) taxa are hermaphroditic in their adult colonies.

In the Orphic tradition, the unaging Chronos was "engendered" by "earth and water", and produced Aether and Chaos, and an egg.West, p. 178. The egg produced the hermaphroditic god Phanes who gave birth to the first generation of gods and is the ultimate creator of the cosmos. Pherecydes of Syros in his lost ("the seven recesses"), around 6th century BC, claimed that there were three eternal principles: Chronos, Zas (Zeus) and Chthonie (the chthonic).

He gave it, and described how he began wearing the ring on his left hand, "with which I hold my paper, so that the thought of you clasps me tight."Quoted in Cronin, p. 173. At this time he began working on a philosophical novel, Séraphîta, about a hermaphroditic angel united by the love of a mortal man for a compassionate and sensual woman. Balzac explained that she was his model for the latter.

Only Phoronis ovalis naturally builds colonies by budding or by splitting into top and bottom sections which then grow into full bodies. In experiments, other species have split successfully, but only when both parts have enough gonadal (reproductive) tissue. All phoronids breed sexually from spring to autumn. Some species are hermaphroditic (have both male and female reproductive organs) but cross-fertilize (fertilize the eggs of other members), while others are dioecious (have separate sexes).

Compsobuthus werneri female with young (white) A few arthropods, such as barnacles, are hermaphroditic, that is, each can have the organs of both sexes. However, individuals of most species remain of one sex their entire lives. A few species of insects and crustaceans can reproduce by parthenogenesis, especially if conditions favor a "population explosion". However, most arthropods rely on sexual reproduction, and parthenogenetic species often revert to sexual reproduction when conditions become less favorable.

The corolla tube is hairy inside. Hermaphrodite corolla have dimensions of 1.4–2.4 x 1.3–1.7mm they are slightly longer than the calyx the female corolla tube is 1.3–1.8mm making it equal to or slightly longer than the calyx. The corolla lobes can vary greatly and can be circular, elliptic, oblong obtuse, suberect or recurved. V. strictissima is a gynodioecious plant meaning that some plants are hermaphroditic and other plants are female plants.

Eggs are released with mouse faeces and thus dispersal is passive - through the movement and defecation of mice. Adult worm infections in mice held under laboratory conditions persist for 6–12 months. Worms reproduce sexually via the cross fertilization of segments, each of which contains a complete complement of male and female reproductive organs (hermaphroditic). Shelled embryos develop in the ovaries through spiral cleavage, to become infective larvae with 3 pairs of hooks.

|
Selfing or self-fertilization is the union of male and female gametes and/or nuclei from same haploid, diploid, or polyploid organism. It is an extreme degree of inbreeding. Selfing is widespread – from unicellular organisms to the most complex hermaphroditic plants and animals (especially invertebrates). In unicellular organisms such as Protozoa, selfing can occur when two individuals (or their cell nuclei) interbreed that were produced from a previous mitotic division of the same individual.

Chamaecrista fasciculata, the partridge pea, is a species of legume native to most of the eastern United States. It is an annual which grows to approximately 0.5 meters tall. It has bright yellow flowers from early summer until first frost, with flowers through the entire flowering season if rainfall is sufficient. The flowers are hermaphroditic, although a fraction of plants, less than 5%, do not produce sufficient pollen to reproduce as males.

T. gibbosus has poisonous flesh, organs, and spines, and is known to secret poisonous mucus in defense or when it is disturbed. This poison can be fatal to humans or other marine organisms that come into contact it. T. gibbosus is hermaphroditic; all individuals of this species are born female, but some may change into males as they grow. Juveniles live together in small schools, but individuals become solitary as they mature into adulthood.

Blue-tailed damselflies (Ischnura elegans) mating In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms, usually for the purposes of sexual reproduction. Some definitions limit the term to pairing between animals, while other definitions extend the term to mating in plants and fungi. Fertilization is the fusion of two gametes. Copulation is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization.

The part of the spikelet that bears the florets is called the rachilla. A spikelet consists of two (or sometimes fewer) bracts at the base, called glumes, followed by one or more florets. A floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The flowers are usually hermaphroditic—maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role.

Royal Ann cherry trees are perennial semi-dwarfs that bloom early April with harvest in mid-summer. They are deciduous trees that can be characterized by dark green leaves and clusters of small fragrant white flowers that are about 2.5-3 centimeters wide. Royal Ann flowers are hermaphroditic, containing both male and female reproductive organs, however, the tree cannot self-pollinate. Another pollinator species is necessary in order for fertilization to occur, most commonly bees.
|
|
Even when a colony is sexually reproductive, a large proportion of polyps remain infertile, which demonstrates the greater importance of asexual reproduction and growth. Z. sociatus colonies do not become reproductive until they reach a certain size. They use external fertilization, and are mostly hermaphroditic, although some are male or protogynous (female and then male). Z. sociatus was found to reproduce seasonally in Panama, and synchronizes the release of gametes with extremely low tides.

Unlike most species of plants that require the use of pollinators for pollination the H. Psittacorum naturally prefers the absence of pollinators for pollination. In other words, it is well capable of pollinating itself, any use of pollinators can do more harm than good. The flower has both male parts (anthers) and female parts (stigma and pistil), also referred to as a hermaphroditic angiosperm.PLANTS Profile for Heliconia psittacorum (Parakeetflower) USDA PlantsLinnaeus, Carl von f. 1782.

The snails mate from May through July, and lay eggs from June through July. They are hermaphroditic; however, it is unclear if self-fertilization is possible. The eggs, numbering 8 to 14, are approximately 2 mm in diameter, spherical, transparent, and very distinctive within a cluster. Generally, Novisuccinea chittenangoensis eggs are not found to have a heavy gelatinous layer surrounding the entire cluster, which is associated with egg masses of Succinea sp.

"It is suggested that bodies ... only live within the productive constrains of certain highly regulatory schemas." People must be "culturally intelligible as males or females". While the standard model says that sex is biologically determined, Fausto-Sterling challenges this by stating "From the sum total of hermaphroditic evidence, the conclusion that emerges is that sexual behavior and orientation as male or female does not have an innate, instinctive basis."Fausto-Sterling 2000, p. 46.

Paul Albert Ancel (21 September 1873 – 27 January 1961) was a French professor of medicine who worked on cytology, physiology, and embryology. He studied endocrine functions of the Leydig cells of the testes along with Paul Bouin. Ancel was born in Nancy from where he received a degree in medicine in 1899. He received a doctor of science in 1903 with a thesis on the hermaphroditic gonad of the snail Helix pomatia.

Though individual polyps are either male or female, entire colonies are typically hermaphroditic. Unlike the vast majority of other corals, black corals have no protection against abrasive materials such as sand and rocks and lack muscular development which can help the corals to hide. These factors can lead to sediment tearing the soft tissue, resulting in death. In response, corals live near crevices, which allows much of their body to be protected.

A Nommo figure of the Tellem people The Nommo or Nummo are primordial ancestral spirits in Dogon religion and cosmogony (sometimes referred to as demi deities) venerated by the Dogon people of Mali.Schulz, Dorothea, Culture and Customs of Mali, ABC-CLIO (2012), p. 68, (retrieved March 18, 2020) The word Nommos is derived from a Dogon word meaning "to make one drink." Nommos are usually described as amphibious, hermaphroditic, fish-like creatures.

A tactical fiber-optic cable assembly (TFOCA) is a fiber-optic cable that is designed for high strength, and to be used in harsh environments. TFOCAs are used in aerospace, oil-drilling, military, and water purification applications. TFOCA connectors are generally hermaphroditic, so any two can be connected. Several US Department of Defense specifications and military specifications apply to TFOCA, including DOD-1678, MIL-C-83526/12-01, and MIL- STD-810C.

Ramshorn snails are hermaphroditic;Ramshorn Snail – The Care, Feeding and Breeding of Ramshorn Snails Red Ramshorn Snail Factoids two organisms of any sex have the ability to breed and produce offspring. Ramshorn snails lay eggs in globules, which tend to be brownish in color. The globules contain about a dozen or so eggs, though it can vary. The globules are translucent, so it is possible to visually see the new snails develop in size.

Molgula manhattensis is small, spherical, brownish-grey in color, somewhat translucent, and feels soft and rubbery to the touch. Like other ascidians, they have two siphons (incurrent and excurrent), through which they draw water for ventilation and filter-feeding, and also for releasing their gametes. They are hermaphroditic, and release sperm and eggs into the water for external fertilization, unlike some other species of Molgula which may be viviparous (e.g. M. citrina).

The distinctive flowers are on long, bare stalks, which grow from the base of the stems. Each flower has five thin, elongated petal-like lobes, radiating in a star-shape, from a central raised disk or annulus. The colour of most species flowers is shades of reddish brown, except for those of the rare Duvalia parviflora which are cream-coloured. The hermaphroditic flowers measure 1–5 cm in diameter, and have five parts.

In which case they may be either male (staminate) or female (pistillate). Plants may bear either all bisexual flowers (hermaphroditic), both male and female flowers (monoecious), or only one sex (dioecious), in which case separate plants are either male or female flower-bearing. Where both bisexual and unisexual flowers exist on the same plant, it is called polygamous. Polygamous plants may have bisexual and staminate flowers (andromonoecious), bisexual and pistillate flowers (gynomonoecious), or both (trimonoecious).

It is a branched columnar cactus that reaches between 7 and 15 m in height. The number of branches in an adult plant may vary from one to 10. Plants bear a reddish cephalium at the tip of each branch from which purple- red flowers emerge between May and June, during the end of the dry season. The species is hermaphroditic and its flowers are mainly nocturnal, opening at sunset (1900 h) and closing in the morning (1000 h).

Stipa is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to Stipa, which have since been reclassified into new genera. Many species are important forage crops. Several species such as Stipa brachytricha, S. arundinacea, S. splendens, S. calamagrostis, S. gigantea and S. pulchra are used as ornamental plants.

He pursues Iron Jaw until issue #15, in which the character is killed, but continues his crusade. (Iron Jaw returns later in the series.) Chuck also tangles with a hermaphroditic serial killer named the He-She in issue #12. Although his initial adventures focused on his "crimebusting" agenda, as the superhero genre became less popular, stories focused more on the character's school life. With the war over, the school changed from Custer Military Academy to Curtis High School.

There is a record of a hermaphroditic specimen with an ovary on its right side and a testis on its left. Early in development, the embryos are sexually undifferentiated, unpigmented, and possess filamentous external gills; the external yolk sac in this stage weighs . Recognizable sex organs develop by an embryonic length of , and tissue differentiation is complete by a length of . Body pigmentation appears when the embryo is long; the external gills regress at around the same time.

Buddleja hatschbachii is a hermaphroditic subshrub 1 m high with brownish bark. The young branches are quadrangular, and covered with a whitish tomentum, bearing sessile lanceolate leaves 10 - 16 cm long by 2.5 - 4.5 cm wide, membranaceous, glabrescent above, and lanose below. The cream or white inflorescence is 10 - 20 cm long. The sessile perfect flowers occur in pairs of cymes, each with 3 - 12 flowers, borne in the axils of the reduced leaves or bracts.

The sexes are separate in most species, though a few are hermaphroditic or protandric. The gonads are located in the disk, and open into pouches between the arms, called genital bursae. Fertilisation is external in most species, with the gametes being shed into the surrounding water through the bursal sacs. An exception is the Ophiocanopidae, in which the gonads do not open into bursae and are instead paired in a chain along the basal arm joints.

From small to moderate to the tallest in the family, the trunks may be solitary or clustering and lack armament. The reduplicate leaf is regularly or irregularly pinnate, bifid, or entire with pinnate ribs; crownshafts are present in some members and absent in others. Monoecious, dioecious, and hermaphroditic palms occur in the group; a protective prophyll accompanies the inflorescence, and all feature peduncular bracts. Any unisexual flowers are slightly dimorphic, solitary, or in rows; all have syncarpous, triovulate gynoecium.

This minor planet was named after Anagolay, the goddess of the lost things worshipped by pre- Hispanic Tagalogs. In Philippine mythology, Anagolay is the daughter of the hermaphroditic agricultural deity Lakampati (also goddess Ikapati). The name, suggested by Filipino student Mohammad Abqary Alon, was selected among 85 other suggestions in a contest held by the Space Generation Advisory Council's "Name-An-Asteroid" campaign. The official naming citation was published by the Minor Planet Center on 9 September 2014 ().

Sclerotized copulatory organs of Pseudorhabdosynochus epinepheli (left, male; right, female) Pseudorhabdosynochus epinepheli is a small monogenean, about half a millimetre in length. Adults are hermaphroditic. The species has the general characteristics of other diplectanids, with a flat body and a posterior haptor, which is the organ by which the monogenean attaches itself to the gill of is host. The haptor bears two squamodiscs, one ventral and one dorsal, which are made up of numerous rows of rodlets.

Over the next three years they become friends, each saving the other's life several times. Davidge, haunted by dreams of spaceships landing on the planet, leaves in search of help. He finds evidence of humans, but learns that the planet has only periodically been visited by human miners known as Scavengers who use Dracs as slave labor. He returns to warn Jeriba (nicknamed "Jerry") only to discover that Jerry is now with child; Dracs are hermaphroditic and reproduce asexually.

The tree starts flowering when only a few years old. The flowers are hermaphroditic and are probably pollinated by insects with one or two fruits usually developing per inflorescence. Monkeys and large birds such as hornbills help to disperse the seed by carrying the fruit away to consume elsewhere. Where the trees become established the previous root mat disappears, the leaf litter becomes thinner, the soil pH rises and the biodiversity of ground plants and animals decreases.

Janthina globosa is hermaphroditic and reproduces sexually. This means that it does not stay as the sex that it was at birth but begins life as a male, and then exhibits a cycle of protandry, where it morphs into a female in order to reproduce. It does this by laying pale pink eggs on the underside of its float, where they stay attached until they hatch later on in their development (Wilson and Wilson, 1956, 302).

|
Their mating behavior has not been studied, but females are usually larger than males and more numerous (at a ratio of 1 male per 1.6 females). Since no specimens with intermediate gonad morphologies have been collected thus far, it is likely that they are not hermaphroditic as some other goby species are. They have also been observed sheltering in the tentacles of the hoplites corallimorph (Paracorynactis hoplites), with no apparent adverse effects from the stinging cells.

Spermatogenesis has been documented in 12% of cases. There is a hypothetical scenario, though, in which it could be possible for a human to self fertilize. If a human chimera is formed from a male and female zygote fusing into a single embryo, giving an individual functional gonadal tissue of both types, such a self-fertilization is feasible. Indeed, it is known to occur in non-human species where hermaphroditic animals are common, including some mammals.

The Tholians are an extremely xenophobic, non-humanoid hermaphroditic species with a propensity for precision. They first appear in the original series episode, "The Tholian Web", where Spock makes the remark when fired upon by the Tholians: "The renowned Tholian punctuality". Tholian biology required high temperatures around 480 Kelvin (207 °C, 404 °F). They could tolerate lower temperatures for a brief period of time; if they were exposed to temperatures around 380 Kelvin or less, their carapace would crack.

Most Rubiaceae are zoophilous. Entomophilous species produce nectar from an epigynous disk at the base of the corolla tube to attract insects. Ornithophily is rare and is found in red-flowered species of Alberta, Bouvardia, and Burchellia. Anemophilous species are found in the tribes Anthospermeae and Theligoneae and are characterized by hermaphroditic or unisexual flowers that exhibit a set of specialized features, such as striking sexual dimorphism, increased receptive surface of the stigmas and pendulous anthers.

25% of hermatypic corals (stony corals) form single sex (gonochoristic) colonies, while the rest are hermaphroditic. About 75% of all hermatypic corals "broadcast spawn" by releasing gametes eggs and sperm into the water to spread offspring. The gametes fuse during fertilisation to form a microscopic larva called a planula, typically pink and elliptical in shape. Synchronous spawning is very typical on the coral reef and often, even when multiple species are present, all corals spawn on the same night.

While this attachment has become necessary for the male's survival, it will eventually consume him, as both anglerfish fuse into a single hermaphroditic individual. Sometimes in this process, more than one male will attach to a single female as a symbiote. In this case, they will all be consumed into the body of the larger female angler. Once fused to a female, the males will reach sexual maturity, developing large testicles as their other organs atrophy.

Each format has a plug and receptacle defined for each of the A and B ends. USB cables have plugs, and the corresponding receptacles are on the computers or electronic devices. In common practice, the A end is usually the standard format, and the B side varies over standard, mini, and micro. The mini and micro formats also provide for USB On-The-Go with a hermaphroditic AB receptacle, which accepts either an A or a B plug.

Tan and pink tipped variation The giant Caribbean sea anemone's primary mating season is reported to be in late May; however, they may continue to reproduce at a low levels throughout the year. This anemone is generally dioecious but occasionally hermaphroditic. It has a 1:1 to sex ratio (males to females) with no evidence of brooding or of asexual reproduction or division furrowing. The giant Caribbean sea anemone's reproduction scheme has been defined as oviparous → planktonic → lecithotrophic.

Following Rome's disastrous defeat at Cannae, the State's most prominent written oracle recommended the living burial of human victims in the Forum Boarium to placate the gods.Rosenberger, Companion to Roman Religion, pp. 295–298; the discovery of a hermaphroditic four-year-old child was expiated by the state haruspex, who set the child to drown in the sea. Its survival for four years after its birth would have been regarded as extreme dereliction of religious duty.

The flowers are hermaphroditic, having a colour ranging from yellow to green and a double perianth radial symmetry. They are composed of an entire annular calyx, five almost fully developed sepals, a corolla with five petals 2.5 mm long, with five stamens and five or six carpels that enclose the ovary. The style is not recognizable and the stigma is established. The fruits have an almost spherical oval drupe, with a diameter of about 5 mm.
|
|
The leaves are hairless and sometimes shiny on their upper surface, while their lower surface is densely hairy when young, but when mature hairless. Its petioles are 2-7 millimeters long. Its fragrant, hermaphroditic flowers are on 3-8 millimeter long pedicels that have oval, hairy bracteoles that are 2.5-4 by 1-1.5 millimeters. Its sepals are 0.6-1.2 by 4-7 millimeters, covered in dense rust colored hairs, and come to a tapered point at their tip.

They are able to communicate with the different aspects (spiritual, natural and human) of the universe by means of the foye trees. Foye trees also emphasize that machi rituals are co-gendered because the flowers are specifically hermaphroditic. Hence Mapuche Shamans have no gender restrictions in order to engage in the rituals. Most of the machi's are female because women usually tend to provide fertility to the land which helps promote agriculture and ultimately helps the community survive.

These stipules are not sheath-forming. The hermaphroditic flowers are terminal, blooming singly or branched or forked in cymes. The inflorescence is usually dichasial at least in the lower parts, which means that in the axil of each peduncle (primary flower stalk) of the terminal flower in the cyme, two new single-flower branches sprout up on each side of and below the first flower. If the terminal flowers are absent, then this can lead to monochasia, i.e.

Gynodioecy is often referred to as the evolutionary intermediate state between hermaphroditism and dioecy. Gynodioecy has been investigated by biologists dating as far back as to Charles Darwin. Gynodioecy can evolve from hermaphroditism due to certain environmental factors. If enough resources in a population are allocated to the female functions in a hermaphroditic species, gynodioecy will ensue. On the other hand, if more of those resources are divvied up to favor a hermaphrodite’s male functions, androdioecy will result.
|
|
They are hermaphroditic, actinomorphic (radially symmetrical, like in Geranium) or slightly zygomorphic (with a bilateral symmetry, like in Pelargonium). The calyx and the corolla are both pentamerous (with five lobes), petals are free while sepals are connate or united at the base. The androecium consists in two whorls of five stamens each, some of which can be unfertile; the pistil consists of five (less commonly three) merged carpels. The linear stigmas are free, and the ovary is superior.

For example, Hemioniscus balani, a parasitic castrator of hermaphroditic barnacles, feeds on ovarian fluid, so that its host loses female reproductive ability but still can function as a male. This is a case of direct parasitic castration (feeding on host gonads). Indirect strategies are also seen such as diverting host energy from gonad development or secreting castrating hormones. The parasitic castration strategy is used by some larval trematode parasites of snails and some isopod and barnacle parasites of crustaceans.

|
The species blooms in early summer after leaves have developed. These whitish blooms are formed in lateral clusters up to long, with each hermaphroditic flower bearing five petals and thirty stamens, the latter of which give the flower clusters a fluffy appearance. The ovoid fruits of the tree most often bear a single seed. Symplocos coreana is a very similar species, possibly conspecific, only differing in its broader and coarsely serrated leaves that bear many hairs on both sides.
|
|
The tubular, hermaphroditic flowers (also covered by golden brown scales) are about 4–5 cm long and cream or pinkish brown in colour. The flowers lack petals and are formed of tubular bracteoles and tube-like calyx, obscurely 5-lobed. The round fruits, about 10–13 cm in diameter and covered with spines, are clustered along the branches. The fruit is a capsule, 5-valved, containing many reddish brown seeds about 4–5 cm long and 2–3 cm wide.

In traditional Roman religion, a hermaphroditic birth was a kind of prodigium, an occurrence that signalled a disturbance of the pax deorum, Rome's treaty with the gods.Veit Rosenberger, "Republican nobiles: Controlling the Res Publica," in A Companion to Roman Religion (Blackwell, 2007), p. 295. But Pliny observed that while hermaphrodites were once considered portents, in his day they had become objects of delight (deliciae) who were trafficked in an exclusive slave market.Plutarch, Moralia 520c; Dasen, "Multiple Births in Graeco-Roman Antiquity," p. 61.

Cydippid larva of Bolinopsis sp., a few mm long Adults of most species can regenerate tissues that are damaged or removed, although only platyctenids reproduce by cloning, splitting off from the edges of their flat bodies fragments that develop into new individuals. The last common ancestor (LCA) of the ctenophores was hermaphroditic. Some are simultaneous hermaphrodites, which can produce both eggs and sperm at the same time, while others are sequential hermaphrodites, in which the eggs and sperm mature at different times.

In many Gnostic systems, the aeons are the various emanations of the superior God or Monad. Beginning in certain Gnostic texts with the hermaphroditic aeon Barbelo, the first emanated being, various interactions with the Monad occur which result in the emanation of successive pairs of aeons, often in male–female pairings called syzygies. The numbers of these pairings varied from text to text, though some identify their number as being thirty. The aeons as a totality constitute the pleroma, the "region of light".

In the euhermaphrodite stage the shrimp act as a male between moults and as a female immediately following a moult. During this hermaphroditic stage the shrimp gradually lose their male organs, likely because more energy is being allocated to the development of female reproductive organs. Lysmata wurdemanni employs a 'pure searching' tactic for mate-finding in which the males are constantly searching for receptive females. Males use olfactory organs (aesthetascs) on their antennnules to detect soluble female sex pheromones (distance pheromones).
|
|
In most species, the sexes are separate and there is little sexual dimorphism, but a few species are hermaphroditic and some parasitic forms show large differences between the sexes. Some Cymothoidans are protandrous hermaphrodites, starting life as males and later changing sex, and some Anthuroideans are the reverse, being protogynous hermaphrodites that are born female. Some Gnathiidans males are sessile and live with a group of females. Males have a pair of penises, which may be fused in some species.
|
|
Most polychaetes have separate sexes, rather than being hermaphroditic. The most primitive species have a pair of gonads in every segment, but most species exhibit some degree of specialisation. The gonads shed immature gametes directly into the body cavity, where they complete their development. Once mature, the gametes are shed into the surrounding water through ducts or openings that vary between species, or in some cases by the complete rupture of the body wall (and subsequent death of the adult).

Alpha Centauri is a hermaphroditic hexapod from Alpha Centauri and, being effectively genderless is referred to as "it" as opposed to "he" or "she". It is tall, green, has one large blue eye, six arms and a high-pitched voice, wears a long yellow cape and walks with a nervous gait. It is prone to cowardice and hysterics. It has a low opinion of Earth, describing it as a "'remote and unattractive" planet, but regrets that its appearance can frighten humans.

In India, the tender leaves of the plant are used in the making of curries, but the plant is cultivated mainly as a fibre crop in drier regions. In order to cultivate the plant properly, moisture is required during the growing period, so rainfall should be at least 100 mm or more per month during the crop cycle, with a fairly uniform temperature. The plant is hermaphroditic. It produces large, cream-coloured flowers characterised by a reddish purple or scarlet throat.

Macrostomum lignano is a free-living, hermaphroditic flatworm. It is transparent and of small size (adults reaching about 1.7 mm), and is part of the intertidal sand meiofauna of the Adriatic Sea. Originally a model organism for research on developmental biology and the evolution of the bilaterian body plan, it has since expanded to other important fields of research such as sexual selection and sexual conflicts, ageing and the evolution of the bilaterian body plan, ecotoxicology, and, more recently, genomics.

The flowers of Commelinaceae are ephemeral, lack nectar, and offer only pollen as a reward to their pollinators. Most species are hermaphroditic, meaning each flower contains male and female organs, or andromonoecious, meaning that both bisexual and male flowers occur on the same plant. Floral dimorphism may be accompanied by variable pedicel length, filament length and/or curvature, or stamen number and/or position. Species tend to have specific flowering seasons, though local environmental factors tend to effect exact timing, sometimes considerably.

In the Dungeons & Dragons fantasy role-playing game, Demogorgon is a powerful demon prince. He is known as the Prince of Demons, a self-proclaimed title, but one that is acknowledged by mortals and even his fellow demons because of his power and influence. Demogorgon was also named as one of the greatest villains in D&D; history by the final print issue of Dragon. He is depicted as an , reptilian (or amphibious) hermaphroditic tanar'ri with a somewhat humanoid form.

Red mistletoe mainly parasitises Quintinia and Nothofagus species. Its principle host is the black/mountain beech (Nothofagus solandri complex). However, north of latitude 38°S this species utilises tawheowheo (Quintinia serrata), and in the far north has been found on pohutukawa (Metrosideros excelsa), puriri (Vitex lucens) and towai (Weinmannia silvicola), and hence, is the most widely distributed beech mistletoe. P. tetrapetala is hermaphroditic, self- compatible, and is both bird-pollinated and bird-dispersed, yet has an explosive bud-opening mechanism.

Apophallation is the biting off of the penis, known to occur in terrestrial slugs, which are hermaphroditic gastropod mollusks. It has been reported in some species of banana slugs, Ariolimax, and in the distantly related Deroceras laeve. In the mating of banana slugs, the penis is inserted into the body of the partner. The penis may become trapped, perhaps because of the action of a special muscle, in which case the penis is gnawed off by either the partner or the owner.

Dioecy has a demographic disadvantage compared with hermaphroditism: only about half of reproductive adults produce seeds. It is commonly assumed that dioecious species must therefore have fitness advantages to compensate for this cost through increased survival, growth, or reproduction. In trees, compensation is realized mainly through increased seed production by females. This in turn is facilitated by a lower contribution of reproduction to population growth, which results in no demonstrable net costs of having males in the population compared to being hermaphroditic.

Some of the groups that "seeded" each planet were the subjects of genetic experiments, including on Gethen. In the language of its people, "Gethen" means "Winter", and as its name indicates, is a planet that is always cold. The inhabitants of Gethen are sequentially hermaphroditic humans; for twenty-four days (somer) of each twenty-six-day lunar cycle, they are sexually latent androgynes. They only adopt sexual attributes once a month, during a period of sexual receptiveness and high fertility, called kemmer.

Psedoceros reticulatus (commonly known as the mottled flatworm) is a hermaphroditic marine flatworm species that belongs to the Pseudocerotidae family.Tyler S. Artois T., Schilling S., Hooge M. & Bush L.F. (eds). (2019). WoRMS Turbellarians: World List of turbellarian worms (Acoelomorpha, Catenulida, Rhabditophora) (version 2019-03-05).

Although most Rubiaceae species are hermaphroditic, outbreeding is promoted through proterandry and spatial isolation of the reproductive organs. More complex reproductive strategies include secondary pollen presentation, heterodistyly, and unisexual flowers. Secondary pollen presentation (also known as stylar pollen presentation or ixoroid pollen mechanism) is especially known from the Gardenieae and related tribes. The flowers are proterandrous and the pollen is shed early onto the outside of the stigmas or the upper part of the style, which serve as a 'receptaculum pollinis'.

From April through the northern summer, the number of snails copulating increases due to the higher temperature and humidity, which enhance the possibility of oviposition. The pulmonate snails are hermaphroditic, meaning that both female and male sexual organs are present in the same individual. The snails produce both eggs and sperm in the ovotestis (also called the hermaphrodite gland), but it is later separated into two divisions, a sperm duct and oviduct, respectively. Mating takes several hours, sometimes a day.

Lathyrus tuberosus - MHNT Lathyrus tuberosus (also known as the tuberous pea, tuberous vetchling,Tuberous Vetchling, Ontario Wildflowers earthnut pea, aardaker, or tine-tare) is a small, climbing perennial plant, native in moist temperate parts of Europe and Western Asia. The plant is a trailer or weak climber, supported by tendrils, growing to 1.2 m tall. The leaves are pinnate, with two leaflets and a branched twining tendril at the apex of the petiole. Its flowers are hermaphroditic, pollinated by bees.

Colpophyllia natans is a hermaphroditic broadcast spawner, releasing large numbers of gametes synchronously to aid fertilisation. Each individual polyp spawns both eggs and sperm, having the reproductive capabilities of both the male and female sexes. Following fertilisation, the zygote becomes a microscopic larva called a planula, which, upon swimming to suitable substrate, will anchor and establish a new colony. This method of sexual reproduction has a high rate of failure in several of its stages and few new colonies successfully grow.

Quaint hyperbole of plants celebrating steamy nuptials on softly perfumed pedaled beds surrounded the discovery of plant sexuality. Plant sexuality was strongly assimilated to heterosexual models of human affections, even though the majority of the flowers are hermaphroditic. Here Schiebinger reveals how Linnaean taxonomy recapitulated social hierarchies by setting the taxon defined by the male stamens above that defined by female pistils. Best known is her chapter “Why Mammals are Called Mammals.” recounting the torrid history of the breast in eighteenth-century Europe.

Most Vitis varieties are wind-pollinated with hermaphroditic flowers containing both male and female reproductive structures. These flowers are grouped in bunches called inflorescences. In many species, such as Vitis vinifera, each successfully pollinated flower becomes a grape berry with the inflorescence turning into a cluster of grapes. While the flowers of the grapevines are usually very small, the berries are often large and brightly colored with sweet flavors that attract birds and other animals to disperse the seeds contained within the berries.

Male sterility genes cause plants to grow anthers that are stunted or withered and as a result, do not produce pollen. In most plants, there are nuclear fertility restoring genes that counteract the work of the male sterility genes, maintaining the hermaphroditic state of the plant. However, in some species of plants, the male sterility genes win the battle over the nuclear fertility restoring genes, and gynodioecy occurs. Maize farmers take advantage of gynodioecy to produce favorable hybrid maize seeds.
|
|
It would appear that gynodioecy should not persist. In order for it to be maintained, the females need to have some sort of a reproductive advantage over the hermaphroditic population, known as female compensation or female advantage. Female advantage includes an increase in saved energy from not producing pollen and making seedlings of higher quality, since hermaphrodite seedlings are susceptible to homozygous deleterious alleles. Additional advantages include more flowers, higher fruit set, higher total seed production, heavier seeds, and better germination rates.

Drawing of Eptatretus polytrema Drawing of a New Zealand hagfish Very little is known about hagfish reproduction. Embryos are difficult to obtain for study, although laboratory breeding of the Far Eastern inshore hagfish, Eptatretus burgeri, has succeeded. In some species, sex ratio has been reported to be as high as 100:1 in favor of females. Some hagfish species are thought to be hermaphroditic, having both an ovary and a testicle (only one gamete production organ is in both females and males).

H. balani parasitically castrates adults of several species of barnacles, including Semibalanus balanoides, Chthamalus fissus, Chthamalus dalli, and Balanus glandula. Rarely does more than one H. balani parasitize the same host, but under conditions of heavy infestation, a single barnacle may contain as many as seven H. balani individuals. Both the isopod parasite and its barnacle host are hermaphroditic crustaceans with a free-swimming larva and a sessile adult. H. balani is a protandrous hermaphrodite that develops into a female only after attaching to its adult host.

Sempervivum arachnoideum, the cobweb house-leek, is a species of flowering plant in the family Crassulaceae, native to the Alps, Apennines and Carpathians. Growing to tall by wide, it is a rosette-forming succulent perennial, valued in cultivation for its ability to colonise hot, dry areas via offsets. The specific epithet arachnoideum refers to its furry central rosettes (long ciliate leaf margins), resembling spider webs. It flowers in July, with pink flowers that are raised on stems and are hermaphroditic (having both male and female organs).

Orthalicus reses reses snails are hermaphroditic, and cross-fertilization is common. Liguus individuals are able to locate each other by following mucus trails, and Orthalicus reses reses likely do the same. They mate and nest in late summer and early fall during the wettest part of the rainy season. They lay approximately 15 eggs per clutch in a cavity that is dug into the soil humus layer, usually at the base of a tree, and take anywhere from 24 to 105 hours to deposit their eggs.

In the myth of Pangu, developed by Taoist monks hundreds of years after Lao Zi, the universe began as an egg that symbolizes the primordial state of Taiji. A primeval hermaphroditic giant named Pangu, born inside the egg, broke it into two halves: the upper half became the sky, while the lower half became the earth. As the god grew taller, the sky and the earth grew thicker and were separated further. Finally Pangu died and his body parts became different parts of the earth.

Lloyd's major contribution to botany was in the field of plant reproduction. His contributions to the field include a mechanistic treatment of different modes of self-pollination in hermaphroditic plants, a genetically defined continuum of plant gender, early development of theory of the evolution of separate sexes in plants, and with C.J. Webb, a challenge to conventional views of the evolution of heterostyly. Because of his ideas and work on population biology of plants, he is sometimes referred to as the "W.D. Hamilton in plant biology".

The lifetime of adult worms varies tremendously from one species to another but is generally in the range of 1 to 8 years (see following table). This lifetime of several years is a result of their ability to manipulate the immune response of their hosts by secreting immunomodulatory products. Helminths can be either hermaphroditic (having the sex organs of both sexes), like tapeworms and flukes (not including the blood fluke), or have their sexes differentiated, like the roundworms. All helminths produce eggs (also called ova) for reproduction.

Salmacisia is a fungal genus in the family Tilletiaceae. It is a monotypic genus, containing the single species Salmacisia buchloëana, first described as Tilletia buchloëana in 1889, and renamed in 2008. Plants infected by the fungus undergo a phenomenon known as "parasitically induced hermaphroditism", whereby ovary development is induced in otherwise male plants. Because of the pistil-inducing effects of the fungus, the authors have named the species pistil smut; it is the only species in the order Tilletiales known to have hermaphroditic effects.

Taiaroa tauhou is a solitary coral that reproduces solely by means of sexual reproduction. It may be a hermaphrodite, as one individual examined contained both eggs and spermaries (sperm producing organs), but other individuals only contained eggs or were exclusively male. It is unclear whether the gonads in the bisexual individual were attached to the body wall. It may be that the males liberate spermaries which are ingested by the females, resulting in internal fertilisation, and this would mean that the animals are not hermaphroditic.

Bursaphelenchus contains a single described hermaphroditic species, okinawaensis, and over 100 described gonochoristic species. They inhabit soil or decaying wood, feeding on the wood itself or fungal hyphae growing in it, such as those of grey mould (Botrytis cinerea). They are sometimes beneficial when they reduce the fungal load inside the wood, but when they consume the plant tissue they are known to cause the death of living trees. These nematodes are phoretic, dispersed between trees when their dauer larvae are transported by insects.

Shiva and Shakti in the form of Ardhanarisvara Hindu mythology has many examples of deities changing gender, manifesting as different genders at different times, or combining to form androgynous or hermaphroditic beings. Gods change sex or manifest as an Avatar of the opposite sex in order to facilitate sexual congress.Smith, B.L., p. 5, Legitimation of Power in South Asia Non-divine beings also undergo sex-changes through the actions of the gods, as the result of curses or blessings, or as the natural outcome of reincarnation.

Panga or panga seabream is the common South African name for Pterogymnus laniarius, a small, ocean-dwelling fish, native to the southeast Atlantic Ocean and southwest Indian Ocean. Alternatively called "torpedo scads", they are cold-blooded with white flesh. Their scales are generally pink in color with whitish underbelly and blue-green stripes running laterally along their sides. Over the course of its life, a panga will undergo periodic sex-changes with as much as 30% of the population being hermaphroditic at a time.

Mating behavior in Nembrotha purpureolineata Acanthodoris lutea laying eggs Nudibranchs are hermaphroditic, thus have a set of reproductive organs for both sexes, but they cannot fertilize themselves. Mating usually takes a few minutes, and involves a dance-like courtship. Nudibranchs typically deposit their eggs within a gelatinous spiral, which is often described as looking like a ribbon. The number of eggs varies; it can be as few as just 1 or 2 eggs (Vayssierea felis) or as many as an estimated 25 million (Aplysia fasciata).

Not only are some of the gifts that are presented to females not nutritionally based, but they can actually affect the fitness of the recipient. For instance, in some hermaphroditic land snails, one partner (the donor) shoots a mucus covered dart at the other called a love dart (the recipient). This ultimately increases the fitness of the donor but at a great risk to the recipient. This dart changes the sperm storage ability of the receiver, not to mention the risk of injury from the dart itself.

It is an herbivorous species which lives in the fresh spray zone of the Chittenango Falls, in partially sunlit areas with lush herbaceous growth. Several parameters appear to be influential in its habitat selection, namely humidity, substrate, temperature, vegetation, and water quality. Novisuccinea chittenangoensis is a hermaphroditic species, and its mating season is from May through July. It lays egg clusters, each one containing an average of 8 to 14 eggs, at the base of plants, under matted vegetation, or in loose, wet soil.
|
|
The principles of the Trivers-Willard hypothesis can also be applied to sequentially hermaphroditic species, in which individuals undergo sex change. Ghiselin (1969) proposed that individuals change from one sex to another as they age and grow because larger body size provides a greater advantage to one sex than the other. For example, in the bluehead wrasse, the largest males have 40 times the mating success of smaller ones. Thus, as individuals age, they can maximize their mating success by changing from female to male.

An alternative type of plug and socket connection uses hyperboloid contacts, which makes a more reliable electrical connection. When working with multi-pin connectors, it is helpful to have a pinout diagram to identify the wire or circuit node connected to each pin. Some connector styles may combine pin and socket connection types in a single unit, referred to as a hermaphroditic connector. These connectors includes mating with both male and female aspects, involving complementary paired identical parts each containing both protrusions and indentations.

Some hermaphroditic land snails begin mating with an elaborate tactile courting ritual. The two snails circle around each other for up to six hours, touching with their tentacles, and biting lips and the area of the genital pore, which shows some preliminary signs of the eversion of the penis. As the snails approach mating, hydraulic pressure builds up in the blood sinus surrounding an organ housing a sharpened dart. The dart is made of calcium carbonate or chitin, and is called a love dart.

The leaves are large, thick, blade oblongs that are 10–27 cm long, attached to short petioles about 1 cm long. Its male flowers have 5 petals and 1 cm long stamens united into 5 bundles, while its hermaphroditic flowers have ovaries with 9–10 loculi. Its fruits are globose, about 4–5 cm in diameter, with red pericarp. In Vietnam, the plant's young leaves are used for food, such as being cooked in soup, or eaten fresh in a dish called banh xeo.

Ciona intestinalis is a hermaphroditic broadcast spawner but cannot self-fertilize. Eggs and sperm, when released, can stay in the water column for 1 to 2 days while the larvae are free- swimming for 2 to 10 days. Ciona intestinalis is considered to be an invasive species and grows in dense aggregations on any floating or submerged substrate, particularly artificial structures like pilings, aquaculture gear, floats and boat hulls, in the lower intertidal to sub-tidal zones. It often grows with or on other fouling organisms.

Acanthopale pubescens is an erect, soft-wooded shrub or a shrubbery herb that can grow up to 2.5 m tall. The leaves are oppositely arranged and the largest leaves are 8–24 cm long, ovate to elliptic with distinct drip-tip and are narrow at the base and apex. The Flowers are hermaphroditic and have radial symmetry and the Inflorescences are lateral with terminal racemose heads and hairy on the inside. The flower is white with purple marking and the corolla is hairy on the outside.

University of California. 2009. For a long time, this hermaphroditic slug was thought to reproduce only by self-fertilization; solitary captive specimens produced offspring and the species had never been observed mating. Genetic analysis provided evidence of crossing and the species is now believed to have a mixed breeding system, with an individual having the ability to fertilize itself or cross-fertilize, exchanging sperm with a mate. In the wild it has one generation per year (univoltine), with all individuals maturing rather synchronously in autumn.

The patron god is Dionysus, a god gestated in the thigh of his father Zeus, after his mother died from being overwhelmed by Zeus's true form. Aphroditus was an androgynous Aphrodite from Cyprus with a religious cult in which worshipers cross-dressed,Macrobius, Saturnalia iii.8 in later mythology became known as Hermaphroditus, the son of Hermes and Aphrodite who merged bodies with the water nymph Salmacis, transforming him into an androgynous being. In Phrygia there was Agdistis, a hermaphroditic being created when Zeus unwittingly impregnated Gaia.

Chrysoblephus puniceus ('golden-eyed purple'), also known as the slinger seabream, is a species of sea bream from southern African waters, ranging from Zavora, Mozambique to Coffee Bay in the Eastern Cape, from the shallows to a depth of 130m. Slingers are the only protogynous hermaphrodite in the Natal area, with females becoming male at approximately 5 years or 38 cm.Allsop, D.J. and S.A. West, 2003.

The stem of P. serratum is up to in diameter and covered with the black, fibrous bases of old spirally arranged leaves, four-ranked or tristichous, as in the closely related family Juncaceae, a family in which it was previously placed - it also has close affinities with the bergpalmiet (Tetraria thermalis) in the Cyperaceae. The strap-like lanceolate leaves are rigid, with a high silica content, narrow, leathery, grey-green, and with toothed margins. The small, brown flowers are on a branched inflorescence about 1 m in length. Plants are hermaphroditic and pollination is anemophilous.

The purpose of these structures is debated—they are light-sensitive and may serve to detect bioluminescent prey; it has also been proposed that the organs themselves may be luminescent and act as lures. Ipnops have a well-developed lateral line, which has been suggested to have a primary sensory function given the degenerate state of their other senses. Like other bathypteroid fishes, Ipnops is hermaphroditic, with male and female gonads combined into a single organ. External fertilization is likely, possibly with ripe eggs held by the pelvic fins to facilitate fertilization.

California sheephead populations vary spacially in reproductive potential and reproductive capacity, and these differences are correlated with the natural sea surface temperature gradient. Fish in cooler waters may require less energy for growth and may be able to convert more energy into reproduction than fish at warmer sites. Population densities and sex ratios of hermaphroditic fishes are also intimately linked to ecological factors and human activities. Spatial and temporal changes in fishing pressure, coupled with environmental changes across populations over time, tend to affect the reproductive potential of each population of California sheephead.

Charles Darwin's book Fertilisation of Orchids included an illustration of the head of a moth with its proboscis laden with several pairs of pollinia from Orchis pyramidalis This hardy plant reaches on average of height, with a maximum of . The stem is erect and unbranched. The basal leaves are linear-lanceolate with parallel venation, up to long, the cauline ones are shorter and barely visible on the stem. The arrangement of hermaphroditic flowers in a compact pyramidal shape is very distinctive and gives the orchid its common name.

Father-Mother The story takes place in a fictional fantasy world called Zenozoik, and begins in a town called Halstedom. The game commences with Ghat, the game's protagonist, regaining consciousness after setting off an explosion which kills Father-Mother, an ostensibly hermaphroditic creature, which has raised a large and influential family. Ghat is one of Father-Mother's children, who turned on it after discovering its secret. Ghat runs away from the town, chased by his brothers and sisters seeking to kill him, and is banished from his family.

It has been the subject of various studies on the evolution of metazoan development. A. queenslandica was first discovered in 1998 on Heron Island Reef by Sally Leys during a survey of sponge species, and was formally described by John Hooper and Rob van Soest in 2006. Like most sponges it has a biphasic life cycle, passing through a planktonic phase whilst a larva, but later becoming a benthic dweller. It is hermaphroditic, and reproduces via spermcast spawning, meaning it releases sperm into water but retains eggs, which are fertilised internally.

The related species Speleonectes tanumekes Xibalbanus tulumensis (previously Speleonectes tulumensis – Speleonectes = 'cave swimmer'; tulumensis = 'occurring at Tulum' – Xibalbanus = 'from Xibalba') is a venomous, hermaphroditic crustacean found in anchialine caves on the Yucatán Peninsula in the Caribbean Sea. This blind remipede liquefies the body contents of other crustaceans with a venom similar to that of rattlesnakes, and which includes digestive enzymes and a paralysing toxin. In her 1987 description, Smithsonian biologist Jill Yager wrote 'Body elongate, slender, without eyes or pigment. Cephalic shield small, tapering slightly at anterior end.

Genomic conflicts often arise because not all genes are inherited in the same way. Probably the best example of this is the conflict between uniparentally (usually but not always, maternally) inherited mitochondrial and biparentally inherited nuclear genes. Indeed, one of the earliest clear statements about the possibility of genomic conflict was made by the English botanist Dan Lewis in reference to the conflict between maternally inherited mitochondrial and biparentally inherited nuclear genes over sex allocation in hermaphroditic plants. A single cell typically contains multiple mitochondria, creating a situation for competition over transmission.

Some intersex female bears mate and give birth through the tip of the clitoris; these species are grizzly bears, brown bears, American black bears and polar bears. Although the bears have been described as having "a birth canal that runs through the clitoris rather than forming a separate vagina" (a feature that is estimated to make up 10 to 20 percent of the bears' population), scientists state that female spotted hyenas are the only non-hermaphroditic female mammals devoid of an external vaginal opening, and whose sexual anatomy is distinct from usual intersex cases.

The Solarians create robots with the Three Laws but with a warped meaning of "human". Solarian robots are told that only people speaking with a Solarian accent are human. This enables their robots to have no ethical dilemma in harming non-Solarian human beings (and they are specifically programmed to do so). By the time period of Foundation and Earth it is revealed that the Solarians have genetically modified themselves into a distinct species from humanity—becoming hermaphroditic and psychokinetic and containing biological organs capable of individually powering and controlling whole complexes of robots.

Under the Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research summarised by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus, and of most of the previous family, into the Malvaceae. Tilia species are mostly large, deciduous trees, reaching typically tall, with oblique-cordate leaves across. As with elms, the exact number of species is uncertain, as many of the species can hybridise readily, both in the wild and in cultivation. Limes are hermaphroditic, having perfect flowers with both male and female parts, pollinated by insects.

All species are hermaphroditic, carrying both eggs and sperm. Each animal possesses a pair of testes within the tail, and a pair of ovaries in the posterior region of the main body cavity. Immature sperm are released from the testes to mature inside the cavity of the tail, and then swim through a short duct to a seminal vesicle where they are packaged into a spermatophore.(Sexually and Asexually) During mating, each individual places a spermatophore onto the neck of its partner after rupture of the seminal vesicle.

A spikelet consists of two (or sometimes fewer) bracts at the base, called glumes, followed by one or more florets. A floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals. The flowers are usually hermaphroditic—maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role.

However, many other writers have chosen to use science fiction and non-realistic formats in order to explore cultural conventions, particularly gender roles. This article discusses works that have explored or expanded the treatment of gender in science fiction. In addition to the traditional human genders, science fiction has extended the idea of gender to include transgender humans and hypothetical alien species and robots, and imagined trans-real genders, such as with aliens that are truly hermaphroditic or have a "third" gender, or robots that can change gender at will or are without gender.

The trunk is cylindrical, rarely bifurcated, and has a grayish bark with a smooth surface in adult specimens. The leaves are persistent, grouped at the apex of the trunk, and measuring between 40 and 70 cm. The inflorescence is almost 2 m long; the flowers are hermaphroditic, about 4 mm long, with a tubular yellowish green corolla, and arranged in a spiral pattern. Each flower has three ovaries, of which only one develops into a globular fruit, a dark pulpous berry that contains a light- brown, 12-mm-long ovoid seed.

50px Material was copied from this source, which is available under a Creative Commons Attribution 4.0 International License. Stony corals have a great range of reproductive strategies and can reproduce both sexually and asexually. Many species have separate sexes, the whole colony being either male or female, but others are hermaphroditic, with individual polyps having both male and female gonads. Some species brood their eggs but in most species, sexual reproduction results in the production of a free-swimming planula larva that eventually settles on the seabed to undergo metamorphosis into a polyp.

The leaves range between 1–5 cm long and have a silvery-grey coating on both sides with a scaly texture. Although hermaphroditic variations with bisexual flowers have been reported this species is generally regarded as dioecious, with male and female flowers occurring on separate plants. The male flowers are at the ends of branches in disjunct beads, whereas the female flowers grow along panicles in dense clusters typically around 20 cm in length. After the female flower has been fertilised, leafy bracts become enlarged and surround the developing seed.

Unionida parasitic life cycle Glochidia of the mussel Lampsilis higginsii Unionida have a unique and complex life cycle involving parasitic larvae. This larval form used to be described as "parasitic worms" on the fish host, however, the larvae are not "worms" and do not harm fish under normal circumstances. Most of these freshwater mussel species have separate sexes (although some species, such as Elliptio complanata, are known to be hermaphroditic). The sperm is ejected from the mantle cavity through the male's excurrent aperture and taken into the female's mantle cavity through the incurrent aperture.

The insectivorous birds are attracted to the pulsating of the metacercariae in the sporocyst. This will cause the birds to attack and ingest the brood sacs located in the snail's tentacles. After digestion of the broodsac, sporocysts will become cercaria and further develop into adults. Adult Leucochloridium variae are hermaphroditic helminths, but can cross fertilize with other worms if in close enough proximity. The gravid adults will release their eggs into the intestines of the bird to be excreted out with the bird’s feces; thus, continuing the Leucochloridium lifecycle.

While studies have demonstrated homosexual behavior in a number of species, Petter Bøckman, the scientific advisor of the exhibition Against Nature? in 2007, speculated that the true extent of the phenomenon may be much larger than was then recognized: > No species has been found in which homosexual behaviour has not been shown > to exist, with the exception of species that never have sex at all, such as > sea urchins and aphis. Moreover, a part of the animal kingdom is > hermaphroditic, truly bisexual. For them, homosexuality is not an issue.

The spotted hyena is a moderately large, terrestrial carnivore native to Africa. The family structure of the spotted hyena is matriarchal, and dominance relationships with strong sexual elements are routinely observed between related females. Due largely to the female spotted hyena's unique urogenital system, which looks more like a penis rather than a vagina, early naturalists thought hyenas were hermaphroditic males who commonly practiced homosexuality. Early writings such as Ovid's Metamorphoses and the Physiologus suggested that the hyena continually changed its sex and nature from male to female and back again.

This can be verified in the Denver, Colorado, newspaper of the time, including a photograph of him sitting behind bars. Born Paul Kleinbord, he attended high school in Philadelphia, along with Irvin Penn. (The two remained in contact until Penn's death.) After graduation he went on to attend art school for a period of time, also in Philadelphia. He married a second time and his wife gave birth to a son, his first wife having been, in his words, "a stunning beauty" but after marriage he discovered she was hermaphroditic.

Like most tunicates, S. clava is hermaphroditic and produces short-lived pelagic lecithotrophic larvae. They reproduce externally via broadcast spawning, and the reproductive period is highly dependent on sea surface temperatures reaching a critical temperature threshold, between 16 ℃ and 20℃. The reproductive period can vary from 4 to 10 months depending on location. Along the Californian coast in the United States, the reproduction period occurs for 4 months from June to September, while in Denmark and England, the reproduction period is also 4 months but occurs from July to October.

With the first, the technique of obtaining first and second generation hybrids is described for the first time. In 1793, Sprengel established that most hermaphroditic flowers could not be fertilized by their own pollen because their reproductive organs did not reach maturity at the same time (as is the case with Geraniaceae). And we had to wait for the precise observations of the Italian microscopist Giovanni Battista Amici in 1830, to establish that the pollen germs by emitting a pollen tube that progresses to the egg. Geranium doubles.

At the Tin Tazarift site, for instance, historian Amadou Hampate Ba recognized a scene of the 'lotori' ceremony, a celebration of the ox's aquatic origin. In a finger motif, Ba detected an allusion to the myth of the hand of the first Fulani herdsman, Kikala. At Tin Felki, Ba recognized a hexagonal carnelian jewel as related to the Agades cross, a fertility charm still used by Fulani women. There are also details in the paintings which correspond to elements from Fulani myths taught during the initiation rites like the hermaphroditic cow.

Cherimoya sprouts emerging Nitidulidae's beetle on cherimoya flower, Jundiaí, Brazil The flowers are hermaphroditic and have a mechanism to avoid self-pollination. The short-lived flowers open as female, then progress to a later, male stage in a matter of hours. This requires a separate pollinator that not only can collect the pollen from flowers in the male stage, but also deposit it in flowers in the female stage. Studies of insects in the cherimoya's native region as its natural pollinator have been inconclusive; some form of beetle is suspected.

Reproduction for this parasite is unique because of the hermaphroditic nature of this cestode. When it comes to mating, S. solidus has three options: (1) self-fertilization (2) breeding with a sibling (3) breeding with an unrelated individual. There are advantages and disadvantages to each of these three options. For example, self-fertilization is advantageous when no mating partners are around but it is disadvantageous because of inbreeding depression—the reduced fitness of offsprings because of the unmasking of deleterious recessive alleles due to the breeding of closely related individuals.

True hermaphroditic connectors should not be confused with mixed gender connectors, which are described elsewhere in this article. Another closely related type is the stackable connector for electronics, which typically has male pins on one surface, and complementary female sockets on the opposite surface, allowing multiple units to be stacked up like plastic milk crates. Examples of this include stackable banana plugs, and interconnect cables specified for the IEEE-488 instrumentation bus. Stackable mezzanine bus connectors are used on some modular microcomputer accessory boards for systems such as the Arduino add-on daughterboards called "shields".

In many hermaphroditic species, the close physical proximity of anthers and stigma makes interference unavoidable, either within a flower or between flowers on an inflorescence. Within-flower interference, which occurs when either the pistil interrupts pollen removal or the anthers prevent pollen deposition, can result in autonomous or facilitated self-pollination. Between- flower interference results from similar mechanisms, except that the interfering structures occur on different flowers within the same inflorescence and it requires pollinator activity. This results in geitonogamous pollination, the transfer of pollen between flowers of the same individual.

5, 2017, p. 111 Romaine has been compared to Dona Beatriz Kimpa Vita, who professed to be the incarnation of a male Catholic saint, as both of their religious self- identifications "transcended gender". In January 1792, during Romaine's occupation of the city, the mayor of Léogâne referred to the insurgent leader as "hermaphroditic". Ouvière said Rivière wore a turban (other islanders wore headwraps) and appeared like "a prophet of the Roman religion [in] the clothing of a Turk", and later denounced the insurgent leader as "the Muhammad of Saint Domingue".

Strasburgeriaceae is a small family of flowering plants in the order Crossosomatales, endemic to New Zealand and New Caledonia. It contains two genera, Strasburgeria and Ixerba. Both genera have simple, evergreen, alternated leaves, often in worl-like clusters, with gland-tipped serrations, hermaphroditic, pentamerous flowers with persistent sepals, clawed petals, flat and long filaments that extend beyond the petals and a persistent style with a punctiform stigma. Fossil pollen named Bluffopollis scabratus, found in deposits from the Paleocene to the Miocene, is almost identical to the pollen of Strasburgeria, although only half its size.

Experminetal type hosts are: Syrian golden hamster. Here, the life cycle of Metagonimus yokogawai will be examined, however Metagonimus takahashii and Metagonimus miyatai follow similar life cycle pattern. All three species are hermaphroditic and capable of self-fertilization. Embryonated eggs are passed into an aquatic environment (fresh or brackish water) each containing a fully developed larva, called a miracidium. Development can’t proceed past this stage unless the eggs are ingested by the first intermediary host, freshwater snails. After the snail host ingests the eggs, miracidia emerge and penetrate the snail’s intestines.

This novel sees the first appearance of the Chelonians, a race of cybernetic humanoid tortoises who appeared subsequently in other spin-off novels and are referenced in The Pandorica Opens. The Chelonians are war-like, hermaphroditic and lay eggs. They have cybernetic enhancements that include X-ray vision and improved hearing, but this advanced state of technology often causes them to consider human-beings as a form of parasite to be removed. Contrary to how they are depicted on the dust jacket art to this book and Zamper, they walk on all fours.

Some larvae preferentially settle onto certain suitable substrates, The mottled anemone (Urticina crassicornis) for example, settles onto green algae, perhaps attracted by a biofilm on the surface. The brooding anemone (Epiactis prolifera) is gynodioecious, starting life as a female and later becoming hermaphroditic, so that populations consist of females and hermaphrodites. As a female, the eggs can develop parthenogenetically into female offspring without fertilisation, and as a hermaphrodite, the eggs are routinely self- fertilised. The larvae emerge from the anemone's mouth and tumble down the column, lodging in a fold near the pedal disc.

There are two main mechanisms of sexual selection in flowering plants, one being intra-sexual competition and the other being female mate choice. Intra- sexual selection is responsible for much of floral evolution and diversification. Intrasexual selection, with the help of pollinators, has also led to some of the most remarkable examples of exaggerated traits of among hermaphroditic plants. Similarly, sexual dimorphism has probably been involved in the evolution of sexual dimorphism in floral traits of dioecious plants, and likely also in the evolution of secondary sexual dimorphism through genetic correlations with floral traits.

The pedicels, which are not articulated at the receptacles, are papilose or glabrous. The flowers are hermaphroditic and actinomorphic, the perianth corolla like, with 6 (8 in Beauverdia) tepals fused at their base to form a floral tube arising around the ovary. There are 6 stamens (8 in Beauverdia), 3 fertile and 3 not (staminodes), rarely 6 (Leucocoryne), in two whorls of three (Tristagma, Ipheion) or one whorl. The filaments which are adnate (fused) to the tepals, uniting at their bases, the anthers dorsifixed (attached at their back) are oblong, yellow brown or green.

In this XX/XO sex determination system, gene expression on the X chromosome is equalized by downregulating expression of genes on both X chromosomes of hermaphroditic XX organisms by half. In these XX organisms, the dosage compensation complex (DCC) is assembled on both X chromosomes to allow for this tightly regulated change in transcription levels. The DCC is often compared to the condensin complex, which is conserved across the mitotic and meiotic processes of many species. This complex is crucial to the condensation and segregation of chromosomes during both meiosis and mitosis.

The closest relatives of Arisaema appear to be Pinellia and Typhonium (although the latter as defined in 2004 seems to be paraphyletic, having given rise to Arisaema and other genera). One unusual trait shared by all Arisaema species, and not those of other genera, is the sex change or act of Sequential hermaphroditism. Arisaema plants are typically male when small, and female or hermaphroditic when large, with a single plant capable of changing sex based on nutrition and genetics, and perhaps changing sex several times during its long life (20 years or more).

Like most barnacles, C. stellatus is hermaphroditic and capable of self- fertilisation when isolated, but individuals typically take on either a male or female role in order to mate. Their penises are significantly longer than their bodies and are used by the stationary "functional males" to search the area for an equally stationary "functional female" neighbour to fertilise. Barnacles of this species produce about 1,000 to 4,000 eggs per brood when functioning as female. The fertilised eggs remain inside the shell of the adult until they are released as nauplii, free swimming larvae which float on currents along with other plankton.

Two specimens of Pseudobiceros bedfordi about to engage in penis fencing Like all flatworms in the genus Pseudobiceros, they are hermaphroditic and have two penises. During mating, they fence with one another, using their penises, attempting to stab and inject sperm in their opponent, while avoiding being fertilized by their opponent. They are able to inseminate their opponent by injecting their sperm into any region of the other's body they are able to penetrate. After successfully injecting the other, the spermatozoa stream through their partner's body on their way to ovaries, where they will fertilize the eggs.

At least three species are known to have evolved separate sexes (dioecy); Ocyropsis crystallina and Ocyropsis maculata in the genus Ocyropsis and Bathocyroe fosteri in the genus Bathocyroe. The gonads are located in the parts of the internal canal network under the comb rows, and eggs and sperm are released via pores in the epidermis. Fertilization is generally external, but platyctenids use internal fertilization and keep the eggs in brood chambers until they hatch. Self- fertilization has occasionally been seen in species of the genus Mnemiopsis, and it is thought that most of the hermaphroditic species are self-fertile.

Aplysia vaccaria is a simultaneous hermaphrodite. Simultaneous hermaphrodites are organisms that have both male and female sex organs that are able to contribute to sexual reproduction at the same time, which is distinct from non-simultaneous hermaphrodites which only have one sex organ present or functional at any one point in time. Being simultaneously hermaphroditic is advantageous because any two individuals are able to reproduce with one another, which facilitates Aplysia vaccaria finding a mate. However, despite having both sex organs functional during reproduction, only one Aplysia vaccaria acts as a sperm donor during the mating encounter.

Moreover similarly to other gastropods in the superfamily Helicoidea, this species uses love darts as part of its mating behavior. During the courtship these snails spear the partner with a calcareous dart.Bernardo Reyes-Tur1, John A. Allen, Nilia Cuellar-Araujo, Norvis Hernández, Monica Lodi, Abelardo A.

At the start of the monsoon, males migrate downriver to meet females, which lay very large numbers of eggs (several millions each). The adults do not guard the eggs or the fry, which require brackish water to develop. The species is sequentially hermaphroditic, with most individuals maturing as males and becoming female after at least one spawning season; most of the larger specimens are therefore female. Fish held in captivity sometimes demonstrate features atypical of fish in the wild; they change sex at a smaller size, exhibit a higher proportion of protogyny and some males do not undergo sexual inversion.

|
In at least one hermaphroditic species, self-fertilization occurs when the eggs and sperm are released together. Internal self-fertilization may occur in some other species. One fish species does not reproduce by sexual reproduction but uses sex to produce offspring; Poecilia formosa is a unisex species that uses a form of parthenogenesis called gynogenesis, where unfertilized eggs develop into embryos that produce female offspring. Poecilia formosa mate with males of other fish species that use internal fertilization, the sperm does not fertilize the eggs but stimulates the growth of the eggs which develops into embryos.

They are hermaphroditic and have distinct tongue-shaped gonads which are red or orange in colour for the female gonad and white for the male. It is estimated that a three-year old scallop releases 15 - 21 million oocytes per emission. There appear to be two spawnings in many parts of the range, normally there is a partial one in the Spring and a full one in late August, however younger scallops have a single spawning event in the late summer. In some areas this pattern is reversed and the major spawning is in the Spring.

Males are believed to be attracted to females by the latter's species-specific lures and pheromones, on which the males home in with the help of their oversized olfactory organs and eyes. Once a female is located, the male latches onto her with his otherwise useless teeth. Through enzymatic processes, the tissues of the male gradually begin to coalesce with the tissues of the female, resulting in a permanent attachment and a shared circulatory system, forming a hermaphroditic chimera. The development of the male's large testes — which was delayed prior to this point — begins, and all other organs in the male's body degenerate.

Roscoe, "Priests of the Goddess," p. 204. In traditional Roman religion, a hermaphroditic birth was a kind of prodigium, an occurrence that signalled a disturbance of the pax deorum, Rome's treaty with the gods, as Diodorus indicated.Veit Rosenberger, "Republican nobiles: Controlling the Res Publica," in A Companion to Roman Religion (Blackwell, 2007), p. 295. Livy records an incident during the Second Punic War when the discovery of a four-year-old hermaphrodite prompted an elaborate series of expiations: on the advice of the haruspices, the child was enclosed in a chest, carried out to sea, and allowed to drown.

However, Callie knows that she is sexually attracted to females, and decides to run away to pursue a male identity. When Cal has a sexual relationship with the Japanese- American photographer Julie at the end of the book, he is able to love "without the need to penetrate the object of his desire". Mark Lawson of The Guardian noted that the cause of Cal's hermaphroditic condition is an inherited recessive gene. According to UC Riverside psychology professor Sonja Lyubomirsky, the novel examines how an individual's traits are due neither solely to nature nor solely to nurture.

Ancient Near Eastern religion knew an elaborate system of benevolent, neutral and malevolent demons (which more resembled Greek daemons than the Christian concept of evil demons), and much of medicine consisted of exorcisms, e.g. of Lamashtu, the hermaphroditic demoness responsible for complications at childbirth and infant deaths. In Assyrian and Babylonian mythology the seven evil demons were known as Shedu or Lamassu, meaning "storm-demon". They were represented in winged bull form, derived from the colossal bulls used as protective genii of royal palaces, the name "Shed" assumed also the meaning of a propitious genius in Babylonian magical literature.

He believes the hermaphroditic sexual innuendos are being overanalyzed and misinterpreted to point towards Shakespeare's own sexuality. In reality, it was commonplace for sexual wordplay to switch between genders. He writes, "Moreover, Shakespeare makes overt rhetorical capital from the fact that the conventions he works in and the purpose for which he uses them do not mesh and from the fact that his beloveds are not what the sonnet conventions presume them to be." Booth maintains that sonnets involving wooing a man are in fact an attempt of Shakespeare to exploit the conventions of sonnet writing.

The first cross was made in 1908 by P.J. Wester, a horticulturist at the USDA's Subtropical Laboratory in Miami. The resulting fruits were of superior quality to the sugar-apple and were given the name "atemoya", a combination of ate, an old Mexican name for sugar-apple, and "moya" from cherimoya. Subsequently, in 1917, Edward Simmons at Miami's Plant Introduction Station successfully grew hybrids that survived a drop in temperature to , showing atemoya's hardiness derived from one of its parents, the cherimoya. The atemoya, like other Annona trees, bears protogynous, hermaphroditic flowers, and self-pollination is rare.

Flowers are hermaphroditic, having both male and female organs. The fruit is a three-lobed inflated papery capsule that is 3–6 cm long, of a faint reddish colour, showy, containing several hard, nut-like seeds which are 5–10 mm in diameter with a pink color. The bark is thin and brown. Branches are upright growing, bend down somewhat as the tree grows, they might break due to poor collar formation, pruning is required to build a strong branching structure and a single stem, if wished, and also for the pedestrians and vehicles clearance if necessary.

One species, Yoda purpurata, is also the first known hermaphroditic hemichordate. It is assumed that these modifications are an adaptation to life in their deep sea habitats.Zoologger: First animal with ovaries on the outside Another member of the family, Terminstomo arcticus, does not have a heart, and has a stomochord that extends from the posterior end of the proboscis through the entire length of the collar.Biogeography and adaptations of torquaratorid acorn worms (Hemichordata: Enteropneusta) including two new species from the Canadian Arctic - TSpace Only one known species (Allapasus aurantiacus) is muscular and robust enough to burrow into substrates.

Ecological selection can be said to be taking place in any circumstance where inheritance of specific traits is determined by ecology alone without direct sexual competition, when e.g. sexual competition is strictly ecological or economic, there is little or no mate choice, females do not resist any male who wishes to mate, all traits will be equally propagated regardless of mating, or the species is hermaphroditic or asexually reproducing, an ecological selection is taking place. For example, environmental pressures are largely responsible for the evolution of different life history strategies between the African honey bee, A. m. scutellata, and the European honey bee.

Since grapevines are hermaphroditic (containing both male and female parts) and usually rely on self-pollination, the presence of wind to circulate pollen or insects usually doesn't influence the success or failure of the pollination stage. While not as influential as temperature, the presence of rain can "wash off" the pollen from the stigma or greatly dilute the stigmatic fluid, causing the pollen to absorb too much water, swelling and bursting before it reaches the ovules.Winkler AJ, Cook JA, Kliere WM and Lider LA General Viticulture 2nd Edition, pgw 126-133 University of California Press. 1974 .

Set in a world less abstract and chaotic than depicted in the later volumes, it introduces Jerry Cornelius as a hip super agent playboy and follows his adventures as he attempts to subvert a plot by his disreputable brother Frank and Miss Brunner to build a super computer for nefarious ends. Jerry is sucked into the plans of Miss Brunner to create the perfect being by merging the bodies of Jerry and herself together. When this is done, a radiantly charismatic hermaphroditic being emerges from the machinery. All who see the new creature fall quaking to their knees.

Physalia physalis, Portuguese man-of-war, is a marine colonial animal that is dioecious; the reproductive medusae within a colony such as this are all of the same sex. In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is of only one sex, in which case the synonym gonochory is more often used. Dioecy may also describe colonies within a species, such as the colonies of Siphonophorae (Portuguese man-of-war), which may be either dioecious or monoecious. An individual dioecious colony contains members of only one sex, whereas monoecious colonies contain members of both sexes.

Particularly, males and hermaphrodites have to have the same fitness, in other words the same number of offspring, in order to be maintained. However, males only have offspring by fertilizing eggs or ovules of hermaphrodites, while hermaphrodites have offspring both through fertilizing eggs or ovules of other hermaphrodites and their own ovules. This means that all else being equal, males have to fertilize twice as many eggs or ovules as hermaphrodites to make up for the lack of female reproduction. Androdioecy can evolve either from dioecious ancestors through the invasion of hermaphrodites or from hermaphroditic ancestors through the invasion of males.

In transgenic XX mice (and some human XX males), SRY alone is sufficient to induce male differentiation. Other chromosomal systems exist in other taxa, such as the ZW sex-determination system in birds and the XO system in insects. Environmental sex determination refers to the determination (and then differentiation) of sex via non-genetic cues like social factors, temperature, and available nutrients. In some species, such as the hermaphroditic clownfish, sex differentiation can occur more than once as a response to different environmental cues, offering an example of how sex differentiation does not always follow a typical linear path.

Some electrical connectors are hermaphroditic because they include both male and female elements in a single unit intended to interconnect freely, without regard for gender. See the discussion of Genderless connectors elsewhere in this article for more detailed information. As an additional complication, certain electronic connector designs may incorporate combinations of male and female pins in a single connector body, for mating with a complementary connector with opposite gender pins in corresponding positions. In these unusual cases, gender is often defined by the shape of the connector body, rather than the mixed-gender connector pins and sockets.
|
|
These types of connectors are not strictly speaking hermaphroditic, since mating connectors are not freely interchangeable. An informal term that has been used for these connectors is "bisexual", in addition to the more official terminology, mixed- gender. Thus, for example, one can have a mixed-gender female plug that connects to a mixed-gender male jack (though a reversed gender assignment of connectors would be a more typical design choice in this example). Male connector pins are often protected by a shell (also called a shroud, surround, or shield), which may envelop the entire female connector when mated.

Most carob trees are dioecious and some are hermaphroditic, so strictly male trees do not produce fruit. When the trees blossom in autumn, the flowers are small and numerous, spirally arranged along the inflorescence axis in catkin-like racemes borne on spurs from old wood and even on the trunk (cauliflory); they are pollinated by both wind and insects. The male flowers smell like human semen, an odor that is caused in part by amines. The fruit is a legume (also known commonly, but less accurately, as a pod), that is elongated, compressed, straight, or curved, and thickened at the sutures.

Additional studies have indicated that terrestrial adult stages of amphibians are also susceptible to non-active ingredients in Roundup, particularly POEA, which is a surfactant. Atrazine has been shown to cause male tadpoles of African clawed frogs to become hermaphroditic with development of both male and female organs. Such feminization has been reported in many parts of the world. In a study conducted in a laboratory at Uppsala University in Sweden, more than 50% of frogs exposed to levels of estrogen-like pollutants existing in natural bodies of water in Europe and the United States became females.

It is an evergreen tree growing to a height of 12–20 m. The leaves are alternate, 10–30 cm long, pinnate, with three to 11 leaflets, each leaflet 5–15 cm wide and 3–10 cm broad, with an entire margin. The flowers are small, 2.5–5 mm, apetalous, discoidal, and borne in erect terminal panicles 15–30 cm wide. Rambutan trees can be male (producing only staminate flowers and, hence, produce no fruit), female (producing flowers that are only functionally female), or hermaphroditic (producing flowers that are female with a small percentage of male flowers).

At this stage, the metacercariae have two options: 1) to wait for the bully (the definitive host) to eat the amphipod or 2) to undergo selfing (progenesis). C. parvum will take up residence in the bully intestine where it will mature and reproduce eggs sexually (if it finds a partner) or via self-fertilization (since trematodes are hermaphroditic). However, if the amphipod is not eaten, the C. parvum metacercariae mature within the amphipod where they produce viable eggs within the cyst in the hemocoel (body cavity) (Lefebvre, 2005). Eggs produced in this fashion remain enclosed in the cyst until the amphipod dies.

A love dart (also known as a gypsobelum) is a sharp, calcareous or chitinous dart which some hermaphroditic land snails and slugs create. Love darts are both formed and stored internally in a dart sac. These darts are made in sexually mature animals only, and are used as part of the sequence of events during courtship, before actual mating takes place. Darts are quite large compared to the size of the animal: in the case of the semi-slug genus Parmarion, the length of a dart can be up to one fifth that of the semi-slug's foot.

Note: The taxonomic placement of all the families mentioned in this article follows the taxonomy of the Gastropoda by Bouchet & Rocroi (2005). There is a complex hermaphroditic reproductive system in pulmonate snails (those snails that have a lung rather than a gill or gills.) Their reproductive system is completely internal, except for the active protrusion (eversion) of the penis for copulation. The outer opening of the reproductive system is called the "genital pore"; it is positioned on the right hand side, very close to the head of the animal. This opening is virtually invisible however, unless it is actively in use.

Spermatozoa, in this case human, are a primary component in normal semen, and the agents of fertilization of female ova. Semen, also known as seminal fluid, is an organic fluid created to contain spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize the female ovum. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim".

The hermaphroditic (or bisexual) flowers are mainly pollinated by bats (Cynopterus and Rousettus) and arboreal mammals (Lion-tailed Macaque, Brown Palm Civet, Indian Giant Squirrel, Nilgiri Langur, and Indian Giant Flying Squirrel). These mammals and other rodents that visit the flowers such as Dusky-striped Squirrel and Malabar Spiny Dormouse also act as flower predators as they consume a substantial number of flowers. The flowers are also visited by a number of bird species, including Indian White-Eye, Square-tailed Bulbul, Yellow-browed Bulbul, Brown-cheeked Fulvetta, Common Rosefinch, Kerala Laughingthrush, and White-cheeked Barbet. However, flowers visited by birds tend to be aborted.

The lesser African threadfin occurs over muddy bottoms in shallow coastal waters at depths between , and they are often observed in estuaries and lagoons. Its diet is dominated by crustaceans but it will feed on small fishes. The stomach contents of specimens taken from the open sea had almost no detritus while those taken in estuaries had 31% of their stomach contents made up of detritus In a study near Lagos in Nigeria it was found that 25% of the females present had developed from the juvenile stage, i.e. had not been males, while the remainder had passed through a hermaphroditic phase having been males.

The Sethian cosmogony as most famously contained in the Apocryphon ("Secret book") of John describes an unknown God, very similar to the orthodox apophatic theology, but different from the orthodox teachings that this God is the creator of heaven and earth. Orthodox theologians often attempt to define God through a series of explicit positive statements: he is omniscient, omnipotent, and truly benevolent. The Sethian hidden transcendent God is, by contrast, defined through negative theology: he is immovable, invisible, intangible, ineffable; commonly, "he" is seen as being hermaphroditic, a potent symbol for being, as it were, "all-containing". In the Apocryphon of John, this god is good in that it bestows goodness.

Meanwhile, due to the chain of events, Cartman decides Connor's scheme has become too complicated and tries to quit, but Connor convinces him to stay involved by revealing that the townspeople of South Park have lied to Cartman about his true father. Although they previously claimed his hermaphroditic mother was his father, Connor insists this is a lie. Cartman confronts his school teacher Mr. Garrison and Garrison's old hand puppet Mr. Hat, who admits to Cartman there was indeed a cover-up. Mecha- Streisand roars threateningly and continues her reign of destruction as the episode ends on a cliffhanger, setting the stage for 201.

The encysted metacercaria of P. skrjabini tend to have a round and circular shape with a cyst wall that consists of a fragile outer later and thicker middle and inner layers. Excysted metacercariae of P. skrjabini have an oral sucker and a ventral sucker measuring 80-120 µm and 120-60 µm in diameter, respectively. The morphological characteristics of adult worms of P. skrjabini are an elongated body with scattered, singularly arranged cuticular spines, branched testes and ovaries, and a ventral sucker that is larger than the oral sucker. Due to the presence of both ovaries and testes in P. skrjabini parasites, they are hermaphroditic.

Silaum silaus is an erect, glabrous umbellifer with woody, stout and cylindrical tap roots, which are hot and aromatic. S. silaus has dark grey or black petioles at the top; petiole remains are found at the bottom of the stem, which is solid and striate. Its umbels are 2–6 cm in diameter, are terminal or axillary, and compound, with 4 to 15 angled rays of 1–3 cm; the peduncle is larger than the rays, and both are papillose. The flowers are mostly hermaphroditic. Silaum silaus has 2–4-pinnate leaves, which have a triangular and lanceolate outline, a long petiole and the primary divisions are long-stalked.

This was not true, as demonstrated by the existence of an unedited Gatchaman version released by ADV Films in the US, in which Keyop rarely, if ever, used profanity. The in-story explanation for Keyop's unique manner of speech is that he is an artificial life form with a speech impediment because of slightly defective genetic engineering. The main villain, known as Zoltar in BotP, had an unusual background due to the hermaphroditic nature of the original Berg Katse character. In an episode where Katse's female half was featured (BotP title: "The Galaxy Girls"), she was introduced as a separate character, Zoltar's sister, for BotP.

Feminist kinship relations are dependent on the liberation of women, LGBTQ persons, youth, the elderly, and intersex (hermaphroditic and pseudohermaphroditic) individuals. To extend liberation into daily home life, a participatory society aims to provide the means for traditional couples, single parents, lesbian, gay, bisexual, transsexual, transgender, and intersex parents, communal parenting, polygamy (especially polyandry), polyamorous and multiple parenting arrangements to develop and flourish. It is believed that within the home and the community, the task of raising children must be elevated in status. Highly personalised interaction between children and adults should be encouraged, and responsibilities for these interactions must be distributed equitably throughout society without segregating tasks by gender.

Outwardly, the palms in the four genera of Chuniophoeniceae appear quite different. Chuniophoenix are small palms from the forest understory with clustered stems; Kerriodoxa is a squat, single-stemmed rainforest palm; Nannorrhops is a sprawling desert palm with branching stems; and Tahina is a massive solitary palm from exposed limestone outcrops. They differ significantly in their flowering strategies, too. Chuniophoenix species flower regularly throughout their lives (pleonanthic) and produce hermaphroditic flowers (rarely single gender); Kerriodoxa are also pleonanthic, but are always dioecious; Nannorrhops stems die after flowering (hapaxanthic), though the much-branched plant survives; Tahina produces a massive terminal inflorescence and dies after fruiting.

Alnus serrulata has unisexual flowers and is monoecious. Shown here: maturing male flower catkins on the right, last year's female catkins on the left. Ilex aquifolium is dioecious: (above) shoot with flowers from male plant; (top right) male flower enlarged, showing stamens with pollen and reduced, sterile stigma; (below) shoot with flowers from female plant; (lower right) female flower enlarged, showing stigma and reduced, sterile stamens (staminodes) with no pollen A "perfect" flower has both stamens and carpels, and may be described as "bisexual" or "hermaphroditic". A "unisexual" flower is one in which either the stamens or the carpels are missing, vestigial or otherwise non-functional.

This experiment would suggest that the Coolidge effect is not applicable since the males of the Gryllodes sigillatus do not prefer novel females. Further research done on spiders also supports the possibility of absence of the Coolidge effect in certain species. Another study that focused on the Coolidge effect in simultaneously hermaphroditic species confirmed the validity of the Coolidge effect in freshwater snail Lymnaea stagnalis. Biomphalaria glabrata, another simultaneous hermaphrodite freshwater snail, does not exhibit sex-specific effects of partner novelty, and thus there is either no Coolidge effect in the species or no difference between the degrees to which the effect is expressed in the respective sexes.

In the late 1970s, he was among the first to introduce mitochondrial (mt) DNA to population biology. This seminal work laid the foundation for phylogeography, a field for which he is recognized as the founding father. Among the many phylogeographic applications for which his laboratory paved the way were genetic assessments of marine and freshwater turtles, catadromous eels, unisexual fishes, and regional assemblages of birds, fishes, mammals, herps, and marine invertebrates. In the 1990s, Avise capitalized upon highly polymorphic microsatellite loci to analyze animal mating systems in nature, on creatures ranging from sea spiders and snails to polyembryonic armadillos to numerous fishes, including male-pregnant pipefishes and seahorses, and hermaphroditic killifishes.

The leaf blade is usually dissected, ternate or pinnatifid, but simple and entire in some genera, e.g. Bupleurum. Commonly, their leaves emit a marked smell when crushed, aromatic to foetid, but absent in some species. The defining characteristic of this family is the inflorescence, the flowers nearly always aggregated in terminal umbels, that may be simple or more commonly compound, often umbelliform cymes. The flowers are usually perfect (hermaphroditic) and actinomorphic, but there may be zygomorphic flowers at the edge of the umbel, as in carrot (Daucus carota) and coriander, with petals of unequal size, the ones pointing outward from the umbel larger than the ones pointing inward.

The Asian sheepshead wrasse, Semicossyphus reticulatus, is a species of wrasse, one of the largest, native to the western Pacific Ocean, where it is only known from around the Korean Peninsula, China, Japan, and the Ogasawara Islands, where it inhabits rocky reef areas. It can reach in total length and the greatest weight recorded for this species is . This species is valued as a food fish in its native range. Asian sheepshead wrasse in captivity giving indication of size The Asian sheepshead wrasse, also known as kobudai in Japan, is a hermaphroditic species, meaning that it has both male and female organs which allows it to change its sex.

Triops longicaudatus is usually greyish yellow or brown in color, and differs from many other species by the absence of the second maxilla. Apart from Triops cancriformis, it is the only tadpole shrimp species whose individuals display as many as three reproductive strategies: bisexual, unisexual (parthenogenetic), and hermaphroditic; see below. Triops cancriformis is easily recognizable by its yellow carapace with dark spots, whilst T. longicaudatus individuals have a uniform carapace. The species also appeared about 50 million years later, and, as its name suggests, its elongated tail structures (cercopods) are often nearly as long as the rest of the body; including the cercopods, the body may reach in length.

The 1977 novelization of Creature from the Black Lagoon by Carl Dreadstone offers a completely different origin for the Gill-man, who in this version of the story is a hermaphroditic giant, almost as big as the Rita itself, weighing in at 30 tons. This Gill-man is both cold-blooded and warm-blooded and also has a long whiplike tail. The gigantic creature is dubbed "AA", for "Advanced Amphibian", by the expedition team members. After slaying most of the team members, destroying a Sikorsky helicopter, and kidnapping Kay more than once, the Gill- man is killed by the crew of a United States Navy torpedo boat.

The Patchy Environment Model states that plants will want to maximize the use of their resources through the change of their sex. For example, if a plant will benefit more from the resources of a given environment in a certain sex, it will want to change to that sex. Furthermore, Size Dependent Sex Allocation outlines that in sequential hermaphroditic plants, it is preferable to change sexes in a way that maximizes their overall fitness compared to their size over time. Similar to maximizing the use of resources, if the combination of size and fitness for a certain sex is more beneficial, the plant will want to change to that sex.

Free-living flatworms are mostly predators, and live in water or in shaded, humid terrestrial environments, such as leaf litter. Cestodes (tapeworms) and trematodes (flukes) have complex life-cycles, with mature stages that live as parasites in the digestive systems of fish or land vertebrates, and intermediate stages that infest secondary hosts. The eggs of trematodes are excreted from their main hosts, whereas adult cestodes generate vast numbers of hermaphroditic, segment-like proglottids that detach when mature, are excreted, and then release eggs. Unlike the other parasitic groups, the monogeneans are external parasites infesting aquatic animals, and their larvae metamorphose into the adult form after attaching to a suitable host.

The hermaphroditic duct, a highly glandular duct of comparatively even diameter, traverses the greater portion of the first coil of the body to enter the accessory glands. All of these structures are in a quiescent condition, and in size and configuration probably fall far short of their fully developed state in the sexually mature condition. The same is likewise true of the gonad. While the duct leading to it from the accessory glands is clearly apparent throughout the first part of its course, it gradually approaches the vanishing point, and cannot with certainty be traced to a gonad, which is accordingly drawn in its hypothetical position.

G. repens is a hermaphroditic plant species that is also plagued by M. violaceum, but it is usually only partially diseased. The same branch can have healthy and diseased flowers, and some of the diseased flowers can still have functional stigmas and produce seeds; whereas, the stigmas in diseased flowers of most host species are usually greatly reduced in their function or aborted, leading to sterility. A study conducted by López-Villavicencio et al. (2005) drew the conclusion that M. violaceum had recently undergone a host shift to G. repens from another diseased Caryophyllaceae because of the disease’s failure to completely infect and sterilize G. repens.

The life cycle of B. acheilognathi involves a definitive host, a fish, and an intermediate host, a copepod. The adult tapeworm is hermaphroditic; each proglottid has a complete set of both male and female reproductive organs and produces eggs via self-fertilization. The tapeworm is sensitive to temperature, in addition the species is thermophilic; lower temperatures interfere and delay development and completion of the life cycle. The eggs are released into the water through the fish fecal material, where they hatch into free-swimming hexacanth (six-hooked) larvae. Between 1–28 days, the eggs will hatch according to the water temperature range it is in.

It is a deciduous or semi-evergreen shrub that reaches a size of 1–2 m height, very branched, with thin branches, arched, flexible and glabrous. The leaves are alternate, simple, little petiolate, with 2–6 cm long green lanceolate, elliptical-rhomboidal or slightly obovate lamina, with 3 nerves parallel from its base, irregularly crenate-dentate in its distal half. The leaves would turn a yellowish red colour in autumn. Blooming in spring and snow white in colour, its flowers are hermaphroditic, actinomorphic, of ± 1 cm diameter, arranged in axillary corimbos, each with 5 free sepals, 5 white petals, numerous stamens shorter than the petals.

She resided in Zurich, Switzerland for many years and was part of the Carl Jung inner circle, along with Crowley. The notion of a hermaphroditic God, drawn from Kabballah, was suggested to Jung by Alice Lewisohn, and commented on by Jung in a dream analysis seminar. Jung urged Alice Lewisohn to flee Europe at the onset of World War II in a letter in which he suggested that suicide would be a better option than for her to be "sent to Poland." In 1927 Lewisohn closed the Neighborhood Playhouse after a dozen years of success, including landmark productions such as 1925's The Dybbuk.

Like other members of the genus Pseudobiceros, P. hancockanus is hermaphroditic with each individual able to function as either a male or female. Mating between two such worms involves penis fencing, as each worm tries to inject sperm into the other with one of its two stubby penises, while trying to avoid being inseminated itself. One explanation advanced for this behavior is that the female role entails more investment in the resulting fertilized eggs. Another possible explanation is that the duel awards mating advantage to the better of two dueling partners—so that penis duel's loser, becoming the "female," is compensated by creating offspring with genes even better than hers.

LGBT themes in Hindu Epics involve Hindu deities or heroes whose attributes or behavior can be interpreted as lesbian, gay, bisexual, transgender, or as having elements of gender variance and non-heterosexual sexuality. Traditional Hindu literary sources do not speak of homosexuality directly, but changes of sex, homoerotic encounters, and intersex or third gender characters are often found both in traditional religious narratives such as the Vedas, Mahabharata, Ramayana and Puranas as well as in regional folklore. Hindu epic has many examples of deities changing gender, manifesting as different genders at different times, or combining to form androgynous or hermaphroditic beings. Gods change sex or manifest as an Avatar of the opposite sex in order to facilitate sexual congress.

In addition, Freyr is referred to as the "son" of Njörðr and the goddess Skaði in the Poetic Edda poem Skírnismál. In his 1 CE work Germania, Tacitus describes rituals surrounding a deity by the name of Nerthus, a theonym that is etymologically ancestral to Old Norse Njörðr. However, the figure described by Tacitus is female. Based on this scholars have suggested a Proto-Germanic hermaphroditic deity or a gender aspectual pair (similar to Freyja and Freyr), identified the obscure Old Norse goddess name Njörun as a potential name for the otherwise unnamed goddess, and in some cases identified a potential reflex of a narrative about Njörðr and his sister-wife in Saxo Grammaticus's 12th-century work Gesta Danorum.

Species in the freshwater gastropod family such as the Caenogastropoda from the class Prosobranchia, are largely self-fertilizing; however after many generations of selfing, a physiological barrier halts sperm generation in that organism, and only allows for the introduction of foreign sperm. Gametes form in the ovotesties, an organ which produces both ova and sperm, and pass down into the hermaphroditic duct to the albumen gland, the junction of where the common duct splits to either vas deferens or oviduct, where they are stored until they are needed for either mating or self- fertilization. It is believed that this junction acts as a regulatory mechanism via contracting muscles, to help direct sperm or eggs into the correct ducts.

This possibility is referenced in Foundation and Earth where it is discovered that the Solarians possess a strong police force of unspecified size that has been programmed to identify only the Solarian race as human. (The novel takes place thousands of years after The Naked Sun, and the Solarians have long since modified themselves from normal humans to hermaphroditic telepaths with extended brains and specialized organs) Similarly, in Lucky Starr and the Rings of Saturn Bigman attempts to speak with a Sirian robot about possible damage to the Solar System population from its actions, but it appears unaware of the data and programmed to ignore attempts to teach it about the matter.

In the 1990s, a group of Chicago collectors, including Bob Roth, founder of the Chicago Reader, and Ann Nathan and Judy Saslow, both of whom have opened acclaimed galleries, organized Intuit: The Center for Intuitive and Outsider Art, which leads tours of Midwestern self-taught artists and has its own exhibition space. Paul Waggoner, an eccentric himself, was an art dealer and champion of outsider art.Trevor Jenses, "Offbeat Gallery Owner", Chicago Tribune, Saturday, March 22, 2008, section 1, p. 17 Carl Hammer, an art dealer in Chicago, has handled much strange, figurative outsider art, including the epic novel, illustrated with hermaphroditic girls traced from coloring books, of Henry Darger, and the naive portraits of society ladies of Lee Godie.

Although all the World State hatcheries attempt to improve the yield of the various production processes, the Mombasa hatchery is a few hundred ahead of the others in the number of embryos produced from a single ovary (London: 16,012, Singapore: approx 16,500, Mombasa: approx 17,000). In addition to racial harmony, gender roles appear to have been eliminated in the World State. Both men and women are equals in society. However, a third pseudo-sex has been engineered: freemartins, a hermaphroditic group of humans who appear to have been grown as, and conditioned to live in society as females, but are sterile and exhibit some male characteristics, including the growth of facial hair.

Eggs of N. salmincola are light brown, ovoid, and operculate at one end, with a small blunt projection at the other end. They measure 0.087 mm to 0.097 mm by 0.038 mm to 0.055 mm. There are normally 5 to 16 eggs in the uterus, and their heaviness allows them to sink rapidly in water. N. salmincola is a digenic trematode, which means that it is an unsegmented worm that is flattened dorsoventrally. Adult worms alternate shape from “a sphere to a long blunt rod.” The worms are 0.8 to 1.1mm long and 0.3 to 0.5 mm wide and are hermaphroditic, having both male and female reproductive organs in the same organism.

Members of this genus have been the subject of research by preeminent plant ecologists, evolutionary biologists, and geneticists, including Charles Darwin, Gregor Mendel, Carl Correns, Herbert G. Baker, and Janis Antonovics. Many Silene species continue to be widely used to study systems, particularly in the fields of ecology and evolutionary biology.Bernasconi et al. 2009. Silene as a model system in ecology and evolution. Heredity. 103:5-14. PMID 19367316 The genus has been used as a model for understanding the genetics of sex determination for over a century. Silene species commonly contain a mixture of hermaphroditic and female (or male-sterile) individuals (gynodioecy), and early studies by Correns showed that male sterility could be maternally inherited,Correns C. 1906.

Third gender, or gender variant, spiritual intermediaries are found in many Pacific island cultures, including the bajasa of the Toradja Bare'e people of Celebes, the bantut of the Taosug people of the south Philippines, and the bayoguin of the pre-Christian Philippines. These shamans are typically biologically male but display feminine behaviours and appearance. The pre-Christian Philippines had a polytheistic religion, which included the transgender or hermaphroditic gods Bathala and Malyari, whose names means "Man and Woman in One" and "Powerful One" respectively; these gods are worshipped by the Bayagoin. The Big Nambas of Vanuatu have the concept of divinely approved-of homoerotic relationships between men, with the older partner called the "dubut".

Eriksson, "Trial Records", 35 Linck admitted to sodomy on account of having been "deluded by Satan" but denied making Mühlhahn suffer. Her marriage to Mühlhahn was the work of other forces, she claimed, since Satan had tracked her since she was born. As for the additional charges, she claimed the wearing of men's clothes was forbidden for married women but not the unmarried; she said she had suffered for her desertions when she "spent weeks in chains and fetters" while held under arrest; she excused her multiple baptisms as motivated by new covenants with God. In sum:Eriksson, "Trial Records", 33-34 Finally, two medical witnesses reported that in examining Linck they had found "nothing hermaphroditic, much less masculine".

The first cost is that in sexually dimorphic species only one of the two sexes can bear young. (This cost does not apply to hermaphroditic species, like most plants and many invertebrates.) The second cost is that any individual who reproduces sexually can only pass on 50% of its genes to any individual offspring, with even less passed on as each new generation passes. Yet sexual reproduction is the more common means of reproduction among eukaryotes and multicellular organisms. The Red Queen hypothesis has been used to explain the significance of sexual reproduction as a means to enable continual evolution and adaptation in response to coevolution with other species in an ever-changing environment.

No longer made today, uli were displayed as part of lengthy fertility rites involving the exhumation and reburial of human skulls, which accompanied the planting of sacred plants. When a newly carved uli was brought out, a shaman assisted in inducing the spirit of the deceased chief to enter the carving, and after the ceremony, the work was kept in the "men's house" where it would continue to aid the successor and his people. Uli figures appear hermaphroditic, having both a phallus and prominent breasts. This blending of male and female features possibly symbolized the fertile and nourishing powers of clan leaders, who were expected to provide for the other members of the clan.

A number of unusual reproductive features have been observed in the species including a number hermaphroditic individuals which have both functional ovaries and testes, with the ability for a change to the preference of one sex also occasionally observed. The species has also been known to hybridise with the closely related species Acanthopagrus australis forming viable offspring, themselves able to backcross with the parent species. This is only known from one coastal lake where the two species are landlocked together for extended periods, promoting interbreeding and the production of offspring with morphological traits intermediate between the two species. The setting required to cause hybridisation, however is too rare to consider the two species subspecies, or even a single species.

The designer of a connection system may use one or both schemes to allow arbitrary connectivity, or even combine both schemes into a single system. When an enforced sense of unidirectionality or "one-way flow" is required for safety or other reasons (for example, AC electrical power connections), a strict assignment of connector genders is implemented to prevent undesired configurations, and gender changers are banned. Some commonly seen examples of hermaphroditic connectors include the SAE connector for 12 V DC power, jackhammer air hose connectors, and the Anderson Powerpole series of modular high-current power connectors. The IBM token ring connector was another widespread example, but it has become obsolete and is being phased out.

In Anostoma depressum the external reproductive pore, located on the right side of the head, leads into a small atrium with which the penis, hermaphroditic duct, and seminal receptacle attach. The first named is a heavy, muscular organ, accompanied by the usual slender vas deferens, their union being effected at some distance from the distal end of the penis, which thus forms a flagellum. The penis and flagellum are both sharply defined and appear to be without muscular attachments, though bound to the body wall by delicate connective tissue strands. In the neighborhood of the outer opening, however, the penis sheath affords attachment for three or four slender muscle bands that Heath inclined to regard as penis retractors.

C. nigoni is noteworthy because it is very closely related to the hermaphroditic species, C. briggsae. Despite substantial differences between C. nigoni and C. briggsae in their modes of sexual reproduction (50:50% female:male versus 99:1% hermaphrodite:male, respectively), their genome sizes (129 Mb versus 108 Mb, respectively), and their protein-coding gene counts (29,167 versus 22,313, respectively), these two species can interbreed to produce not merely viable male and female hybrid offspring, but partially fertile female hybrid offspring. Nevertheless, hybrids between these two species are subject to Haldane's law: heterogametic offspring (males) are much less viable than females. A detailed map of hybrid incompatibility sites for the C. briggsae genome was generated in 2015.

Scholar Nicole Pohl of Oxford Brookes University has argued that Cavendish was accurate in her categorisation of the work as "a 'hermaphroditic' text". Pohl points to Cavendish's confrontations of seventeenth century norms, with regard to such categories as science, politics, gender, and identity. Pohl argues that her willingness to question society's conceptions while discussing topics that were considered in her era best left to male minds, allows her to escape into an exceptional gender-neutral discussion of said topics, creating what Pohl labels, "a truly emancipatory poetic space." Northeastern University professor Marina Leslie remarks that readers have noted that The Blazing World serves as a departure from the habitually male-dominated field of utopian writing.

She also forwarded Darwin a copy of her "little book", Botany for Novices (1864). Becker is one of a number of 19th-century women who contributed, often routinely, to Darwin's scientific work.'Women and Science' section of the 'Darwin & Gender' resources of the Darwin Correspondence Project Her correspondence and work alike suggest that Becker had a particular interest in bisexual and hermaphroditic plants which, perhaps, offered her powerful 'natural' evidence of radical, alternative sexual and social order.Bernstein, S. D., '‘Supposed Differences': Lydia Becker and Victorian Women's Participation in the BAAS' in Clifford, D., Wadge, E., Warwick, A., & Willis, M.

These include random inactivation of one female X chromosome (as observed in Mus musculus; this is called X-inactivation), a two-fold increase in the transcription of a single male X chromosome (as observed in Drosophila melanogaster), and decreased transcription by half in both of the X chromosomes of a hermaphroditic organism (as observed in Caenorhabditis elegans). These mechanisms have been widely studied and manipulated in model organisms commonly used in the laboratory research setting. A summary of these forms of dosage compensation is illustrated below. However, there are also other less common forms of dosage compensation, which are not as widely researched and are sometimes specific to only one species (as observed in certain bird and monotreme species).

An ovotestis is a gonad with both testicular and ovarian aspects. In humans, ovotestes are an infrequent anatomical variation associated with gonadal dysgenesis. In invertebrates that are normally hermaphroditic, such as most gastropods (snails and slugs) in the clade Eupulmonata, an ovotestis is a common feature of the reproductive anatomy. In mice, ovotestes are structured such that the central region is testicular tissue while the poles both contain ovarian tissue. Experiments involving the Sox9 gene, which is initiated by the SRY region of the Y chromosome, have shown the gene’s requirement for testicular differentiation from the presence of ovotestis formation within XX Sox9 trangenic mice. (6) Ovotestis within B6-XYPOS mice allow for gonadal development research within the same tissue to take place in ways previously unavailable.

He painted views of Parisian back streets and boulevards on the Seine and, sporadically, took up New Testament themes. Even before World War I, some of his compositions were in line with the idyllic tradition represented by works of such artists as Nicolas Poussin, Claude Lorrain (called le Lorraine), Antoine Watteau, and most of all Puvis de Chavannes, whose Poor Fisherman at the Louvre inspired a number of Żak's paintings and drawings. The Polish artist began to intensify the stylization of his figural silhouettes and faces. Żak's Arcadia, inspired by original Italian and southern French landscapes as well as those by European art masters, was inhabited by people with a hermaphroditic beauty, undoubtedly linked to Żak's fascination with the Renaissance.

Many species are hermaphroditic, some may be simultaneously hermarphroditic while other species are protogynous hermaphrodites or protandrous hermaphrodites and they adopt the colouring and pattern of the different sex as they transform. Many species produce a "fluffy", round egg mass which the male often guards in a small cave or burrow, the mass is formed by the interlinking of the filaments which cover the half of the surface of each egg which is opposite the micropyle, these filaments are attached to the surface of the egg by a small loaf-like structure. These loaf strauctures are diagnostic of the pseudochromines. The males guard the eggs until they hatch, which varies from 3–7 days after hatching the pelagic larvae disperse.

Mangrove rivulus in Guadeloupe Spawning has not yet been observed in the wild in the mangrove rivulus, but captive studies show that the eggs are positioned in shallow water, sometimes even in places that periodically are on land during low tide. The eggs can continue their development when out of water, but once they are ready to hatch this is delayed until again submerged. The species consists mostly of hermaphrodites which are known to reproduce by self-fertilization, but males do exist, and strong genetic evidence indicates occasional outcrossing. They are also the only simultaneous hermaphroditic vertebrates, and the concentration of males to hermaphrodites can vary depending on the local requirement for genetic diversity (for example, if an increase in the local parasite population occurred, secondary male numbers might increase).

Other characteristic bay-area workboats include sail-powered boats such as the log canoe, the pungy, the bugeye, and the motorized Chesapeake Bay deadrise, the state boat of Virginia. In contrast to harvesting wild oysters, oyster farming is a growing industry for the Bay to help maintain the estuary's productivity as well as a natural effort for filtering impurities such as excess nutrients from the water in an effort to reduce the effects of man-made pollution. The Chesapeake Bay Program is using oysters to reduce the amount of nitrogen compounds entering the Chesapeake Bay. Oysters are hermaphroditic and will change gender at least once during their lifetime, often starting as male and ending as female; there are numerous ways to cook and eat them, as well as recipes and sauces to accompany oyster dishes.

In 1931, De Casseres published a collection of letters the couple sent each other during their courtship, titled The Love Letters of a Living Poet, which highlights the unusual nature of their relationship. In one of the letters, De Casseres describes a dream in which "after thirty years together we were both cremated and our ashes mixed inextricably" and "cast into the depths of the sea" where eventually they are "returned to the ecstatic hermaphroditic union of a great biological-mystical fable." De Casseres died at his home on Manhattan's Riverside Drive at the age of 72.Slaughter, Kevin I. (January 20, 2020) Benjamin De Casseres — includes newspaper obituaries) After his death, Bio De Casseres published his final collection of essays, titled Finis, for which she wrote a brief preface.

The hermaphroditic himatids (the name is derived from the Greek himation, a cloak) have evolved on Genji's predominantly oceanic starside. Their basic form is the ribbon or plate which takes in nourishment and oxygen on its lower (ventral) side, and excretes on the upper (dorsal) side. Their life cycle starts with caterpillar-sized "wrigglers" which swim ashore and adopt a slug-like existence, growing by addition of cell layers to become "tads." Once they have reached a size of about 40 x 10 cm and are too big to get around readily on land, they follow chemical clues to the tidelands where they join older juveniles, the "calves" which are fully intelligent, mostly aquatic, live in bands, and have a culture about which little is known (and even less understood) by human researchers or by the Ihrdizu which used to enslave them.

This would be true even if two hermaphroditic vine varieties, such as Chardonnay, cross pollinated each other. While the grape clusters that would arise from the pollination would be considered Chardonnay any vines that sprang from one of the seeds of the grape berries would be considered a distinct variety other than Chardonnay. It is for this reason that grapevines are usually propagated from cuttings while grape breeders will utilize seedlings to come up with new grape varieties including crossings that include parents of two varieties within the same species (such as Cabernet Sauvignon which is a crossing of the Vitis vinifera varieties Cabernet Franc and Sauvignon blanc) or hybrid grape varieties which include parents from two different Vitis species such as the Armagnac grape Baco blanc, which was propagated from the vinifera grape Folle blanche and the Vitis labrusca variety Noah.

Females are more typical in appearance to other fish, whereas the males are tiny rudimentary creatures with stunted digestive systems. A male must find a female and fuse with her: he then lives parasitically, becoming little more than a sperm-producing body in what amounts to an effectively hermaphrodite composite organism. A similar situation is found in the Zeus water bug Phoreticovelia disparata where the female has a glandular area on her back that can serve to feed a male, which clings to her (note that although males can survive away from females, they generally are not free- living). This is taken to the logical extreme in the Rhizocephala crustaceans, like the Sacculina, where the male injects itself into the female's body and becomes nothing more than sperm producing cells, to the point that the superorder used to be mistaken for hermaphroditic.

In a key scene the young golden Dragon Queen takes off on her mating flight, pursued by the male dragons – until finally one of them catches up with her and they engage in passionate mating high up in the air, their necks and wings curled around each other. On the ground the woman and man who are these dragons' riders share their passion telepathically – and inevitably wildly embrace and kiss, embarking in parallel human mating. Ursula K. Le Guin explores radically alternative forms of sexuality in The Left Hand of Darkness (1969) and again in "Coming of Age in Karhide" (1995), which imagine the sexuality of an alien "human" species in which individuals are neither "male" nor "female," but undergo a monthly sexual cycle in which they randomly experience the activation of either male or female sexual organs and reproductive abilities; this makes them in a sense bisexual, and in other senses androgynous or hermaphroditic.

A pair of L. amboinesis live together with a left Lysmata amboinesis do not live in large groups, more often in pairs, and while omnivorous it is believed they derive much of their nutrition from cleaning parasites and dead tissue from fish. Their mating behaviour has been observed in captivity where it involves little ritual: a pair of fully mature hermaphroditic shrimp will alternate moulting timing, mating occurs shortly following a moult when one shrimp acting as the male will follow the other acting as the female which will brood the fertilised eggs; when the next shrimp moults the roles, and therefore apparent sex, will reverse. In captivity L. amboinesis have been seen to be socially monogamous showing such aggression that if they are kept in groups of more than 2 individuals one pair will kill the rest. While they are not generally seen in large groups in the wild it is unknown if they are socially monogamous in their natural environment.

The maintenance of sexual reproduction (specifically, of its dioecious form) by natural selection in a highly competitive world has long been one of the major mysteries of biology, since both other known mechanisms of reproduction – asexual reproduction and hermaphroditism – possess apparent advantages over it. Asexual reproduction can proceed by budding, fission, or spore formation and does not involve the union of gametes, which accordingly results in a much faster rate of reproduction compared to sexual reproduction, where 50% of offspring are males and unable to produce offspring themselves. In hermaphroditic reproduction, each of the two parent organisms required for the formation of a zygote can provide either the male or the female gamete, which leads to advantages in both size and genetic variance of a population. Sexual reproduction therefore must offer significant fitness advantages because, despite the two-fold cost of sex (see below), it dominates among multicellular forms of life, implying that the fitness of offspring produced by sexual processes outweighs the costs.

Yin et al. (2018) have produced a third-generation genome assembly of C. nigoni, which they used to define which genes differ between the two species and to begin characterizing the functional effects of these differences. They report that most of the difference in gene count between C. nigoni and C. briggsae is due to gene losses in the latter species, that these lost genes encode (in C. nigoni) disproportionately short proteins with disproportionately high levels of male-biased RNA-seq expression, that the lost genes include three Male Secreted Short (mss) genes, and that transgenic restoration of mss-1 and mss-2 from C. nigoni to C. briggsae causes C. briggsae males to become much more effective at reproductive competition (both against other males, and against hermaphroditic self-fertilization). The differences in genome sizes are not due to bulk changes in repetitive DNA, because both genomes have closely similar fractions of repetitive elements (C.

Refusing to be a trophy in Minaka's "Game", Homura attempted to commit suicide through self-immolation just before Minato and his Sekirei arrived. Refusing to let Homura sacrifice himself, Minato winged him, saving his life and causing his power to finally stabilize. As a result, Minato received the power to determine Homura's gender and mentality, but chose to let Homura remain who he is and what he wanted to be, earning Homura's respect. After the final battle, Homura, due to his/her hermaphroditic body, is no longer a "host", and is instead a part-time bartender at a small bar (where he is as popular as ever with the female clientele even though he no longer dates them);Sekirei - 365 Days Without Her, Chapter 2 he is also once again the Sekirei Guardian, but is at peace with himself to the point where he is finally able to tell Minato that he (Minato) really is Homura's chosen Ashikabi.

Standardization allows equipment owned by different hams to be used together without needing adapters in emergencies, at public service events, at field day, during contests, when borrowing equipment, etc. The Anderson Powerpole connector is more expensive than the older de facto standards of the two-wire trailer plug and the Molex connector, but provides a more reliable electrical connection (both mechanically and electrically), and is easier to adapt to a wider range of wire gauges.One Ham’s DC Power Connector Preference; Mal Eiselman Another advantage over the older trailer or Molex connectors is the Powerpole's superior ratings to withstand 100,000 no-load insertions and 250 hot-plugs at full load. The specific hermaphroditic nature of the powerpoles is a significant advantage since batteries can be both a power source or a power sink, a power supply can be connected to a radio and/or a battery, and multiple batteries, radios, and/or redundant power sources can be connected in parallel using the same power distribution panels.

XX C. elegans embryos have much lower xol-1 expression than their XO counterparts, resulting from overall increases in the amount of SEX-1, SEX-2, CEH-39, and FOX-1 transcription produced in the female embryos. This consequent decrease in xol-1 expression then allows higher SDC-2 expression levels, which aids in the formation and function of the DCC complex in the XX hermaphroditic worms, and in turn results in equalized expression of X-linked genes in the hermaphrodite. Though all of the above-mentioned XSEs act to reduce xol-1 expression, experimentally reducing expression levels of these individual XSEs has been shown to have a minimal effect on sex determination and successful dosage compensation. This could be in part because these genes encode different proteins that act cooperatively rather than in an isolated fashion; for example, SEX-1 is a nuclear hormone receptor, while FOX-1 is an RNA-binding protein with properties capable of inducing post-transcriptional modifications in the xol-1 target.

Conner & Sparks (1998), p. 305, "Shiva" The name Ardhanarishvara means "The Lord whose half is a woman". This form of Shiva represents the "totality that lies beyond duality", and is associated with communication between mortals and gods and between men and women.Conner & Sparks (1998), p. 67, "Ardhanarishvara " Alain Danielou says that "The hermaphrodite, the homosexual and the transvestite have a symbolic value and are considered privileged beings, images of the Ardhararishvara.". A similar merger occurs between the beauty and prosperity goddess Lakshmi and her husband Vishnu, forming the hermaphroditic or androgynous Lakshmi-Narayana That ardhnarishwar body tells that half body of husband is for wife. without wife husbands are partial.Conner & Sparks (1998), p. 211, "Lakshmi" In the Bhagavata Purana, Vishnu takes the form of the enchantress, Mohini, in order to trick the demons into giving up Amrita, the elixir of life. Shiva later becomes attracted to Mohini and spills his semen on the rocks which turn into gold. In the Brahmanda Purana, Shiva's wife Parvati "hangs her head in shame" when she sees her husband's pursuit of Mohini.

Inquisitors focused on Céspedes's claim to be, in the parlance of the time, a hermaphrodite; Céspedes argued this state made both marriages licit, as he had been a woman during the first marriage and when he had had sexual intercourse with men, and it was only after a male organ appeared when he gave birth that he went on to have intercourse with women and marry Caño; he argued this natural (intersex/hermaphroditic) condition also made the witchcraft charge, of having the devil's aid in appearing as a man or woman, unfounded. He said the penis-like organ first emerged after childbirth, became engorged when aroused, and retracted inside of him otherwise. He said this organ was initially curved downward by skin, but a surgeon was able to successfully sever this skin. Thereafter, he said, he urinated through his penis and usually ejaculated, and he gave the names of previous partners who could attest to his sex; during the trial, several doctors, female lovers, and male friends testified they had viewed Céspedes as a man.

The major veins are lightly coated and are bright green. The proportion of the pedicel to the major vein is 0.9–1.0, and is bare and bright green. The flower is hermaphroditic with normally- developed pistil and stamens. There are about five or rarely four stamens in a flower, which are as long as the pistil. The number of flowers in an inflorescence is 300–500. The pedicel of a bunch equals 8–12 cm; the bunch is about 15–17 cm long and 11–14 cm wide. There are about 100–130 berries on a bunch; the size of an average bunch is 12–14 cm long and 9–12 cm wide, consisting of 80–90 berries. The bunch is thin, unstructured, wide cone-shaped or branched, or quite dense; the pedicel of a bunch is woody nearly up to the middle and bright red-brownish, while its remaining part, including scion, is grass-like and bright green. The pedicel of a berry, including the receptacle, equals 5–9 mm, and is green.

His 1948 work Sexual Behavior in the Human Male stated that among men "nearly half (46%) of the population engages in both heterosexual and homosexual activities, or reacts to persons of both sexes, in the course of their adult lives" and that "37% of the total male population has at least some overt homosexual experience to the point of orgasm since the onset of adolescence." Kinsey himself disliked the use of the term bisexual to describe individuals who engage in sexual activity with both males and females, preferring to use bisexual in its original, biological sense as hermaphroditic, stating, "Until it is demonstrated [that] taste in a sexual relation is dependent upon the individual containing within his anatomy both male and female structures, or male and female physiological capacities, it is unfortunate to call such individuals bisexual." Although more recent researchers believe that Kinsey overestimated the rate of same-sex attraction, his work is considered pioneering and some of the most well known sex research of all time.
