Overo
Overo refers to several genetically unrelated pinto coloration patterns of white-over-dark body markings in horses, and is a term used by the American Paint Horse Association to classify a set of pinto patterns that are not tobiano. ''Overo'' is a Spanish word, originally meaning "like an egg".''American Paint Horse Association's Guide to Coat Color Genetics'' American Paint Horse Association, 2007.

Lethal White Syndrome
Lethal white syndrome (LWS), also called overo lethal white syndrome (OLWS), lethal white overo (LWO), and overo lethal white foal syndrome (OLWFS), is an autosomal genetic disorder most prevalent in the American Paint Horse. Affected foals are born after the full 11-month gestation and externally appear normal, though they have all-white or nearly all-white coats and blue eyes. However, internally, these foals have a nonfunctioning colon. Within a few hours, signs of colic appear; affected foals die within a few days. Because the death is often painful, such foals are often humanely euthanized once identified. The disease is particularly devastating because foals are born seemingly healthy after being carried to full term. The disease has a similar cause to Hirschsprung's disease in humans. A mutation in the middle of the endothelin receptor type B (''EDNRB'') gene causes lethal white syndrome when homozygous. Carriers, which are heterozygous—that is, have one copy of th ...

Dominant White
Dominant white (W) is a group of genetics, genetically related coat color alleles on the KIT (gene), KIT gene of the horse, best known for producing an White (horse), all-white coat, but also able to produce various forms of Pinto horse, white spotting, as well as bold Horse markings, white markings. Prior to the discovery of the W allelic series, many of these patterns were described by the term Sabino horse, sabino, which is still used by some breed registry, breed registries. White-colored horses are born with unpigmented pink skin and white hair, usually with dark eyes. Under normal conditions, at least one parent must be dominant white to produce dominant white offspring. However, most of the currently-known alleles can be linked to a documented spontaneous mutation that began with a single ancestor born of non-dominant white parents. Horses that exhibit white spotting will have pink skin under the white markings, but usually have dark skin beneath any dark hair. There are ...

Pinto Horse
A pinto horse has a coat color that consists of large patches of white and any other color. Pinto coloration is also called paint, particolored, or in nations that use British English, simply coloured. Pinto horses have been around since shortly after the domestication of the horse. Pinto colors can come in a number of genetically distinct patterns, which have different visual characteristics and tend to make white or leave colored different areas of the horse. These include tobiano, sabino, splashed white, frame, and manchado. A pinto horse may also have a combination of these patterns, such as tovero. Pinto patterns can be found in various breeds of horses, notably including the American Paint Horse. Color breed registries such as the Pinto Horse Association of America record pedigree and horse show results for pinto horses, regardless of ancestry. Both the terms "Pinto" and "Paint" may sometimes refer to breeds or registries rather than coat color. Pinto patterns are vi ...

American Paint Horse
The American Paint Horse is a breed of horse that combines both the conformational characteristics of a western riding, western stock horse with a pinto horse, pinto spotting pattern of white and dark equine coat color, coat colors. Developed from a base of spotted horses with American Quarter Horse, Quarter Horse and Thoroughbred bloodlines, the American Paint Horse Association (APHA) breed registry is now one of the largest in North America. The registry allows some non-spotted animals to be registered as "Solid Paint Bred" and considers the American Paint Horse to be a horse breed with distinct characteristics, not merely a color breed. Registration The American Paint Horse's combination of color and conformation has made the American Paint Horse Association (APHA) the second-largest breed registry in the United States. While the colorful coat pattern is essential to the identity of the breed, American Paint Horses have strict bloodline requirements and a distinctive stock-h ...

Sabino Horse
file:Sabino-Pinto-Puerto-Rican-Paso-Fino.jpg, A sabino horse with extensive roaning Sabino describes a distinct pattern of white spotting in horses. In general, Sabino patterning is visually recognized by roaning or irregular edges of horse markings, white markings, belly spots, white extending past the eyes or onto the chin, white above the knees or hocks, and "splash" or "lacy" marks anywhere on the body. Some sabinos have patches of roan (horse), roan patterning on part of the body, especially the barrel and flanks. Some sabinos may have a dark leg or two, but many have four white legs. Sabino patterns may range from slightly bold face or leg horse markings, white markings—as little as white on the chin or lower lip—to horses that are fully white. The known causes of the sabino patterns are the SB-1 allele and several other dominant white#Allelic_series, dominant white (W) alleles on the KIT (gene), ''KIT'' gene. The genetics behind some types of sabino, such as that fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tobiano
Tobiano is a spotted color pattern commonly seen in pinto horses, produced by a dominant gene. The tobiano gene produces white-haired, pink-skinned patches on a base coat color. The coloration is almost always present from birth and does not change throughout the horse's lifetime, unless the horse also carries the gray gene. It is a dominant gene, so any tobiano horse must have at least one parent who carries the tobiano gene. Other spotting patterns seen in pinto horses include frame overo, splashed white and sabino. In the United Kingdom, tobianos are frequently referred to as "coloured" or as "pied": piebald if black and white, skewbald if white and any base color other than black. Sometimes "painted" is also used. Bay and white tobiano horses are also referred to as tricoloured. Characteristics Tobiano traits generally include the following: * White legs from the hocks and knees down * White crossing the back between the withers and the dock of the tail * Whit ...

Splashed White
Splashed white or splash is a horse coat color pattern in the " overo" group of spotting patterns that produces pink-skinned, white markings. Many splashed whites have very modest markings, while others have the distinctive "dipped in white paint" pattern. Blue eyes are a hallmark of the pattern, and splash may account for otherwise "solid" blue-eyed horses. Splashed white occurs in a variety of geographically divergent breeds, from Morgans in North America to Kathiawari horses in India. The splashed white pattern is also associated with Hearing impairment, congenital deafness, though most splashed whites have normal hearing. Splashed white can be caused by multiple variants across two different genes, for which genetic testing is available. Characteristics The splashed white pattern is characterized by the appearance of having been dipped, feet-first, into white paint. Blue eyes An eye is a sensory organ that allows an organism to perceive visual information. It dete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
