In some breeds, homozygous roans can be identified by an indirect DNA marker test. Such horses, with the genotype Rn/Rn, produce 100% roan offspring. Homozygous roans and heterozygous roans (Rn/rn) are identical in appearance.

Normally, the chestnut and roan alleles would be separated during chromosomal crossover, but these two linked genes will usually remain together. Such a horse will produce sex cells that are either E/Rn or e/rn. Mated to chestnut non-roan partners (e/rn), the horse would produce primarily blue roans, or chestnut non-roans, but few chestnut roans and few black non-roans. If, on the other hand, the recessive e and dominant Rn were on the same chromosome, the horse would be expected to produce primarily chestnut roans and non-chestnut non-roans with chestnut, non-roan partners.

Blue roans, such as these may be confused with young gray horses or blue duns Roans are sometimes mistaken for grays. However, grays lighten with age, while roans do not. Gray is one of the most common coat colors found in horses, and is found in almost all breeds. The defining characteristic of the gray coat is that it becomes progressively lighter over time.
|
|
Thoroughbred and Arabian horses registered as "roan" are often gray, especially chestnuts turning gray. Unlike grays, roans do not develop more white hair with age, and without white markings, roans retain colored heads. A blue dun or grullo has no intermingled white hairs in its body coat.

Varnish roans can also be distinguished from true roans by the presence of leopard complex characteristics, such as the white sclera, finely striped hooves, and mottled skin around the eyes, muzzle, and genitals. A Paso Fino with both roan and sabino patterning. The white at the end of the tail indicates gray, as well.

Varnish roan is thought to occur due a single, simple dominant gene on equine chromosome 1 (ECA1). It also appears that specific white patterning genes produce the assorted blanket, leopard, and snowflake coat patterns. Without these white patterning factors, horses with one or two copies of the dominant Lp gene are "varnish roans." Varnish roans can be considered to have many, many very small leopard spots that reflect the mottling of the underlying skin.
|
|
With gray horses, the head is often the first area to lighten, especially around the eyes and muzzle. Also, roans do not lighten with age, while grays always do. The varnish roan is another unusual coloration, sometimes seen in Appaloosa horses, that, like gray, can change with age, but unlike gray, the horse does not become progressively lighter until it is pure white. Varnish roans are created by the action of leopard complex within breeds such as the Appaloosa and are seldom seen elsewhere.

Rabicano is another type of "roaning" or ticking characterized by scattered white hairs centered on the flanks, barrel and white hairs at the base of the tail. Only in the most extreme circumstances is rabicano linked to underlying pink skin. It is unknown if the roaning characteristic of some sabino-type patterns is due to the additional presence of rabicano or a separate mechanism. Rabicanos are also often identified as roans, even among breeds that do not have true roans, such as Thoroughbreds and Arabians.

Common colors are sorrel, bay, black, and grey. Less common are white, roans, palomino, dun, and buckskin. Least common are paint mules or tobianos. Mules from Appaloosa mares produce wildly colored mules, much like their Appaloosa horse relatives, but with even wilder skewed colors.

By adulthood, the varnish roan usually has a base coat of intermingled dark and white hairs, though more white hairs than dark, with mottled skin, color mainly on the cheeks of the face, and around the knees. The darker areas remain at bony points (on the face, usually in a distinct V on the bridge of the nose; on the cheeks, point of shoulder, elbows, knees, point of hips, hock) and it can be seasonal as well. Although classic roans are roan from birth, varnish roans are often born with spots and "roan out" as they age. A horse's appearance can change almost completely, although the original markings are usually visible.

Over 90 percent of Finnhorses today are chestnut. Flaxen manes and tails as well as white markings on the face and legs are common in the breed. As of 2007, only a minority of Finnhorses are any color other than chestnut: 6 percent are bay and 1.2 percent black. Roans, palominos, buckskins and silver dapples exist in smaller numbers.

Anderson is located south of center of Grimes County at (30.487081, -95.987818). Texas State Highway 90 passes through the city, leading north to Roans Prairie and southwest to Navasota, the largest city in Grimes County. College Station is to the northwest, and Houston is to the southeast. According to the United States Census Bureau, Anderson has a total area of , all of it land.

Roaning is also associated with some of the sabino white spotting patterns. There are many patterns in many breeds called "sabino," and these patterns usually feature irregular, rough-edged patches of white that originate from the lower legs, face, and ventral midline. The borders of these white patches can be heavily roaned, and some sabinos can be mistaken for roans. The roaning of sabinos will originate in a white patch, and the roaning is uneven.

Varnish roan Varnish roan describes a horse with coloration similar to roan, but with some changes in color over the years, though not to the extreme of a gray. This type of roaning only occurs in conjunction with the Leopard complex. Varnish roans are born with a dark base coat color, usually with some spotting. As the horse ages, white hairs increase over most of the body, and many spotted markings blur or fade.

For a long period of time, bays and browns were more commonplace than blacks. There were also roans, greys, and chestnuts among them. The colour markings were not unlike those of Clydesdale horses, with the desired pattern being four white stocking and a well-defined bald face. Large Dutch horses (possibly of Brabant and Friesian descent) were imported by William III when he discovered that the cart horses of his era were not strong enough for the task of draining the Lincolnshire Fens.

It reaches Roans Prairie and an intersection with State Highway 30. It continues north through Bedias and other lightly populated sections of Grimes County before entering Madison County. The route enters Madisonville from the south, reaching an intersection with South Street. It turns east at South Street, reaching its northern terminus two blocks later at State Highway 75 (formerly US Route 75), while State Spur 174 continues northward from South Street to an intersection with US Route 190 and State Highway 21.

Blue dun or grullo (also grulla, mouse dun) coloring is created by the dun gene acting on a black base coat, is a coat color with a bluish cast and darker points.Sponenberg, Dan Phillip (2003). "Grullo is the Spanish name for the crane bird, and these horses are similar to the bluish color of the sandhill crane." pg 37. Unlike blue roans, grullos are solid color and appear bluish due to low amounts of pigment in each hair, not interspersed white hairs.
|
|
Today, pedigree analysis, DNA testing, studying possible offspring, and the vividness of primitive markings are used to determine whether a horse is a dun. A red dun may also be confused with a perlino, which is genetically a bay horse with two copies of the cream gene, which creates a horse with a cream-colored body but a reddish mane and tail. However, perlinos usually are significantly lighter than a red dun and have blue eyes. Grullos are sometimes confused with roans or grays.

The colt was surprisingly small, only 14 hands 3 inches with good bone and a "racey" build. Although considered dark bay, he produced a great number of chestnuts and a high percentage of blacks, as well as horses listed as roan out of non-roan mares, suggesting he might have carried the rabicano gene. His sire was also noted to have sired a good number of roans. Additionally, he had "Matchem arms," or 2-3 bars of white hair at the base of the tail.

Charles H. Roans next Mediterranean cruise began with her sailing from Newport 14 September 1956 to join the 6th Fleet. With the eruption of the Suez crisis that fall, she patrolled in the eastern Mediterranean. Since the Suez Canal was now blocked, December found Charles H. Roan bound for the Cape of Good Hope, rounding the African continent for 2 months of duty with the Middle East Force. Between 20 and 27 January 1957, she served as flagship for the Force Commander in a passage up the Shatt-al-Arab to visit Basra, Iraq.

The leopard complex colors, characteristic of the Appaloosa breed, have several manifestations that feature mixtures of white and colored hairs. A varnish roan, one type of leopard complex coat color also called "marble", is an all-over blend of white and colored hairs. Patches of skin that lie close to the bone, such as on the face and legs, and the point of shoulder and point of hip, do not grow as much white hair. These darker patches are called "varnish marks" and are not found in true roans.

State Highway 30 (SH 30) runs from Business SH 6-R in College Station via Roans Prairie to SH 19 in Huntsville. It is known as Harvey Road between Business SH 6-R and FM 158 in College Station, as 11th Street between I-45 and US 190 (Phelps Dr) in Huntsville, and as Riverside Drive east of US 190 (Phelps Dr) in Huntsville. The current version of SH 30, the second route with that designation, was established in 1960. The previous designation existed from 1917 to 1939, when it was replaced with US 277\.

This trait is not seen in true roans, and suggests that, like the white hairs associated with other white markings and patterns, the white hairs of a rabicano may be rooted in unpigmented skin cells. However, the genetic and developmental controls of such roaning are poorly understood, and has not yet been formally studied. While rabicano itself does not produce white markings on the face and legs, it can be confused with some of the numerous sabino patterns, one of which has been mapped to the KIT gene. Other color patterns mapped to KIT include tobiano and true roan.

Baroque influence is also visible in coat colours, with a large number of black horses as well as blue roans, called mohrenkopf referring directly to the Italian expression testa di moro or capo moro, meaning "dark head" or "Moor (dark) head". Besides Mohrenköpfen, the leopard spotted coat colour, named tiger (reflecting the linguistic absence of a distinction between "tiger" and "leopard" cats), is still an active breeding objective of the breed as well, which is unusual for nearly all other European horse breeds. In 1903, the stud book was closed. Since then, Noriker horses are strictly purebred.

Dutch Harness Horse stallion exhibited in the USA The Dutch Harness Horse is distinctive among warmbloods for its high action, and gaining popularity among those saddle seat aficionados who seek a larger, more substantial horse. They are traditionally shown with a braided mane and natural tail, and when shown in-hand often wear a white bridle without a cavesson. The hooves are usually allowed to grow longer than a riding horse's feet, but are never shod with weighted shoes. While the colors black, brown, bay and chestnut are most common, there are greys, true roans, and creme dilutes.

While the specific mutation responsible for roan has not been exactly identified, a DNA test can determine zygosity for roan in several breeds. True roan is always present at birth, though it may be hard to see until after the foal coat sheds out. The coat may lighten or darken from winter to summer, but unlike the gray coat color, which also begins with intermixed white and colored hairs, roans do not become progressively lighter in color as they age. The silvering effect of mixed white and colored hairs can create coats that look bluish or pinkish.

An extensively expressed rabicano Arabian horse. A bay roan that also has bay rabicano features evidenced by the light hairs in its mane and base of tail One pattern of roaning is rabicano, also called white ticking. While true roans have an even intermixture of white hairs throughout the body, except the extremities, the white hairs of a rabicano are densest around the base of the tail and the flank. Rabicano roaning frequently forms rings of white hair around the base of the tail, and in extensively roaned rabicanos, the white hairs may converge to form vertical stripes over the ribcage.

1962 saw the formation of the National Football League (NFL) and the two Roan clubs in Luanshya - Pensulo's which was all African and another Roan Antelope for whites were instrumental in pushing for a multi-racial football league. The two teams decided to merge and the new club was called Roan United. In the first season of the NFL, Pensulo earned the nickname ‘Ginger’ owing to his wing play which resembled that of Nchanga Sports winger Ginger Stevenson who had ginger-coloured hair. In a league match between Roan and Nchanga at Roans’ Kafubu Stadium in April 1962, Pensulo had a great game leading his team to a 4–2 victory.

Colours of bay, chestnut, flaxen chestnut, black, gray and variety of roans have been recorded since they also exist in purebreds.実馬審査体型標準 – 輓系馬 In extreme cases, a horse may have multiple facial markings and all legs marked with white. Open studbook policy has led to pinto (piebald) pattern; one female family Pedigree of Almond Madonna, dam of Angel Gaga used in ban'ei can be traced to single stallion born in 1967, Hanuma while dominant white seen in two horses was spontaneous, manifesting in 2010. Prevalence of hereditary diseases is unknown, since at least one Western scientific source lists breed as "ban-ei" without hereditary diseases.

Price (1883) p. 21. Note: The 2nd Cavalry Regiment would be transitioned into the 5th U.S. Cavalry on August 3, 1861 On 3 March 1855, the 2nd Cavalry Regiment (later to be known as the 5th Cavalry Regiment) was activated in Louisville, Kentucky with troopers drawn from the states of Alabama, Maryland, Missouri, Indiana, Kentucky, Pennsylvania, Ohio, and Virginia. Each company rode mounts of a certain color, so a trooper's company could easily be identified in the confusion of battle, and so that the regiment appeared more splendid and organized during dress parades. Company A rode Grays, Companies B and E rode Sorrels, Companies C, D, F, and I had Bays, Companies G and H rode browns, and Company K rode Roans.

Some horse breeds exclude certain colors that are considered signs of a crossbred animal. For example, other than the Sabino pattern and some recently discovered dominant white alleles in horses with DNA-verified parentage, the Arabian horse registry excludes all spotted horses. The Finnhorse was also bred for decades to exclude all colors but chestnut, and specifically to remove such "fancy" colors as roans, grays and spotted (sabino), which were seen as indicators of foreign blood, though that policy has now changed, as for some particular colors, this might hold true - for example, all present gray Finnhorses can be traced back to a certain gray mare of dubious pedigree. Due to DNA verification of parentage, today many mainstream breed registries that once excluded certain coat colors will now accept them as long as the animal can be proved pureblooded.

Although the term "Blue Ridge" is sometimes applied exclusively to the eastern edge or front range of the Appalachian Mountains, the geological definition of the Blue Ridge province extends westward to the Ridge and Valley area, encompassing the Great Smoky Mountains, the Great Balsams, the Roans, the Blacks, the Brushy Mountains (a "spur" of the Blue Ridge) and other mountain ranges. The Blue Ridge Mountains as seen from Blowing Rock, North Carolina. The Blue Ridge extends as far south as Mount Oglethorpe in Georgia and as far north into Pennsylvania as South Mountain. While South Mountain dwindles to mere hills between Gettysburg and Harrisburg, the band of ancient rocks that form the core of the Blue Ridge continues northeast through the New Jersey and Hudson River highlands, eventually reaching The Berkshires of Massachusetts and the Green Mountains of Vermont.

Also, black and tan, and sometimes liver and tan are known, as well as a variety of color mixtures of those solid colors including roans, roan and tans, tricolors, and those solid colors with additional white markings. Rare colours can appear unexpectedly in certain lines, for instance while an all- white cocker is usually bred by selective breeding of very light golden strains, they can still appear very uncommonly to parents that are dark- colored. A noted occurrence of this happened in 1943, when a grandson of My Own Brucie, Best in Show at the Westminster Kennel Club Dog Show in 1940 and 1941, was born all-white. In its native United States, the American Cocker Spaniel was ranked the 23rd-most popular breed according to registration statistics of the AKC in 2009, a decrease in popularity since 1999, when it was ranked 13th.
