A white horse is born predominantly white and stays white throughout its life. A white horse has mostly pink skin under its hair coat, and may have brown, blue, or hazel eyes. "True white" horses, especially those that carry one of the dominant white (W) genes, are rare. Most horses that are commonly referred to as "white" are actually "gray ...
Albinism is the congenital absence of melanin in an animal or plant resulting in white hair, feathers, scales and skin and reddish pink or blue eyes. [1][2] Individuals with the condition are referred to as albinos. Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify.
The evolution of the horse, a mammal of the family Equidae, occurred over a geologic time scale of 50 million years, transforming the small, dog-sized, [ 1 ] forest-dwelling Eohippus into the modern horse. Paleozoologists have been able to piece together a more complete outline of the evolutionary lineage of the modern horse than of any other ...
The horse (Equus ferus caballus) [ 2 ][ 3 ] is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, close to Eohippus, into the large, single-toed animal of today.
The American White & American Creme Horse Registry was originally named the American Albino Horse Club and was first established by Caleb Thompson and his wife, Ruth. In 1917, Caleb and his brother, Hudson, had bought a white stallion, Old King, and bred him with their Morgan mares. The horses' progeny were also white and the Thompsons called ...
This Thoroughbred stallion (W2/+) has one form of dominant white.His skin, hooves, and coat lack pigment cells, giving him a pink-skinned white coat. Dominant white (W) [1] [2] is a group of genetically related coat color alleles on the KIT gene of the horse, best known for producing an all-white coat, but also able to produce various forms of white spotting, as well as bold white markings.
Equus (/ ˈɛkwəs, ˈiːkwəs /) [3] is a genus of mammals in the family Equidae, which includes horses, asses, and zebras. Within the Equidae, Equus is the only recognized extant genus, comprising seven living species. Like Equidae more broadly, Equus has numerous extinct species known only from fossils. The genus originated in North America ...
Equine coat color genetics determine a horse 's coat color. Many colors are possible, but all variations are produced by changes in only a few genes. Bay is the most common color of horse, [2] followed by black and chestnut. A change at the agouti locus is capable of turning bay to black, while a mutation at the extension locus can turn bay or ...
