In some cases, if one allele is placed on a different chromosome by a translocation, transvection does not occur. Transvection can sometimes be restored in a translocation homozygote, where both alleles may once again be able to pair. Restoration of phenotype has been observed at bithorax, decapentaplegic, eyes absent, and vestigial, and with transgenes of white. In some cases, transvection between two alleles leads to intragenic complementation while disruption of transvection disrupts the complementation.

Another exception is transvection, in which the heterozygous combination of two alleles with mutations in different parts of the gene complement each other to rescue a wild type phenotype.

Transvection is believed to occur through a variety of mechanisms. In one mechanism, the enhancers of one allele activate the promoter of a paired second allele. Other mechanisms include pairing-sensitive silencing and enhancer bypass of a chromatin insulator through pairing-mediated changes in gene structure.

Morbius once developed a serum based on Spider-Man's blood,Morbius the Living Vampire (vol. 2) #5 which would stave off his pseudo-vampirism for short periods of time. Morbius possesses the ability of transvection, which enables him to navigate wind currents and glide for great distances. In Morbius the Living Vampire (vol.

Dracula possesses far greater powers than most vampires. He is superhumanly strong (to the point of standing toe-to-toe and defeating Colossus in single combat), and also possesses superhuman speed, stamina, reflexes, and transvection. He is immune to aging, conventional disease, sickness and most forms of injury. He cannot be killed or permanently injured by conventional means.

Diploid organisms contain two copies of each gene. If these are different (heterozygous / heteroallelic), the two different copies of the allele may interact with each other to cause epistasis. This is sometimes called allelic complementation, or interallelic complementation. It may be caused by several mechanisms, for example transvection, where an enhancer from one allele acts in trans to activate transcription from the promoter of the second allele.

Scene 2: Hecate's cave Hecate, the chief witch, enters carrying serpents and an "unbaptized brat." The witches plan to boil the baby and use its fat to make a transvection ointment that enables them to fly at night, transform themselves into incubi, and have sex with young men. Sebastian enters and asks Hecate to make Antonio impotent. Hecate gives him a charm made from the skins of lizards and snakes.

Since 1980, Dr. Wu's research has focused on the role of chromosome behavior in inheritance and gene activity, with emphasis on the widespread phenomena in which homology between chromosomes plays a role. She coined the term "homology effects" to highlight these phenomena. Her studies explore transvection, the zeste gene, chromosome pairing, and Polycomb-group genes and chromatin remodeling. She has also characterized the mechanisms of bridging promoter and enhancer elements within and between chromosomes.

As stated by nobelist Ed Lewis, "Operationally, transvection is occurring if the phenotype of a given genotype can be altered solely by disruption of somatic (or meiotic) pairing. Such disruption can generally be accomplished by introduction of a heterozygous rearrangement that disrupts pairing in the relevant region but has no position effect of its own on the phenotype" She also studies ultra-conserved elements (UCEs). Her lab has proposed that these highly conserved sequences may play a role in maintaining genome integrity.

Levitation by street artists in Prague Levitation or transvection in the paranormal context is the rising of a human body and other objects into the air by mystical means or meditation. Some parapsychology and religious believers interpret alleged instances of levitation as the result of supernatural action of psychic power or spiritual energy. The scientific community states there is no evidence that levitation exists and alleged levitation events are explainable by natural causes (such as magic trickery, illusion, and hallucination).

The official responsible for recording their statements openly admitted he did not bother writing down many of them, as they were all so similar. There were so many accused that the trials were conducted at two different locations in the village. The evidence fell against the accused fell into three categories: :Transvection (magical levitation) to arrive at the sabbat (witches' sabbath) The location the children and witches went to they called Blockula. :: Children reported being taken by witches and flying on goats, sticks, or even sleeping men.

Most epigenetic changes only occur within the course of one individual organism's lifetime; however, these epigenetic changes can be transmitted to the organism's offspring through a process called transgenerational epigenetic inheritance. Moreover, if gene inactivation occurs in a sperm or egg cell that results in fertilization, this epigenetic modification may also be transferred to the next generation. Specific epigenetic processes include paramutation, bookmarking, imprinting, gene silencing, X chromosome inactivation, position effect, DNA methylation reprogramming, transvection, maternal effects, the progress of carcinogenesis, many effects of teratogens, regulation of histone modifications and heterochromatin, and technical limitations affecting parthenogenesis and cloning.

Her studies have explored transvection in genetics, polycomb-group genes, chromatin pairing and remodeling, and the mechanisms of bridging promoter and enhancer elements within and between chromosomes. She also studies ultra-conserved elements (UCEs), proposing that these highly conserved sequences play a role in maintaining genome integrity, and has discussed potential opportunities for therapeutics harnessing properties of UCEs in many venues, including in TEDx and the Google-sponsored Solve for X program. Wu has made significant contributions in the area of science education in genetics, across many age groups, through work with the Smithsonian Institution and the National Museum of Natural History and is founding director of the Personal Genetics Education Project, which works through schools, online curricula, teacher training, and producers and writers of the television and movie industry through involvement with the trade-supporting organization Hollywood, Health & Society. She is daughter of author Nelson Ikon Wu, sister of actor Ping Wu, and colleague and spouse of Harvard and MIT scientist George M. Church.
