Excerpt: Dominant white is a group of genetically related coat color conditions in the horse, best known for producing an all-white coat, but also for producing some forms of white spotting and white markings. Dominant white horses are born with unpigmented pink skin and white hair with dark eyes, although the amount of white hair can vary. Dominant white is a rare condition, and under normal conditions at least one parent must be dominant white to produce dominant white offspring. However, there are documented cases where dominant white has occurred as a spontaneous mutation. Dominant white can occur in any breed, and has been studied in many different breeds. Two color breeds, the American White Horse and Camarillo White Horse are characterized by their dominant white coats. There are many different forms of dominant white; in genetics, they are labeled W1 through W11. All known dominant white coat colors are associated with the KIT gene. As the name suggests, these known white coats are inherited dominantly, meaning that a horse only needs one copy of a W allele to have the white or white spotted coat. Dominant white is genetically distinct from Sabino and both genetically and visually distinct from gray and cremello. Dominant white is not the same as lethal white syndrome, nor are dominant white horses "albinos". Albinism has never been documented in horses. Some forms of dominant white are thought to result in nonviable embryos when a zygote is has two W alleles (homozygous). However, this has not been verified for all dominant white genetic variations. The dark skin under a white hair coat, easily seen at the muzzle and genitals, shows that this white-looking horse is actually a gray. Most horses that look "white" are actually grays.Dominant white horses are born with pink skin and a white coat, which they retain throughout their lives. Although the term "dominant white" is typically associated with a pure white coat, such horses may be all-white, near-white, partially
