The silver or silver dapple (Z) gene is a dilution gene that affects the black base coat color and is associated with Multiple Congenital Ocular Abnormalities. It will typically dilute a black mane and tail to a silvery gray or flaxen color, and a black body to a chocolaty brown, sometimes with dapples. [1] It is responsible for a group of coat ...
Brindle: One of the rarest colors in horses, characteristics are any base coat color with "zebralike" stripes, but the most common is a brown horse with faint yellowish markings. Usually linked to chimerism , [ 10 ] but one heritable brindle pattern that affects coat texture and color in a family of American Quarter Horses has been named ...
Before domestication, horses are thought to have had these coat colors. [1] 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 Heck horse. In terms of equine coat color genetics, all of these shades are based on the dun gene acting as a dilution gene over the black gene. Because the grulla color is not due to the gray gene, a grulla horse remains the same basic color from birth, though some minor shade variation may occur from summer to winter coats. If a grulla also ...
The silver or silver dapple gene acts only on black hair. On a black base coat, it lightens the body to a brown color and the mane/tail to a cream or silver shade; on a bay base coat, it lightens the mane and tail to cream or silver. It does not affect chestnut (red) coloring. A genetic test exists for the silver gene. [6]
The flat reddish-brown color and lack of easily identified black points can confuse even knowledgeable horse persons. Silver dapple horses usually hint at black or dark gray pigment at the roots of the mane and tail, and where their silver points end on the legs. Silvers look a bit "off"-chestnut.
Equine coat color genetics discusses color genes in horses, including a brief description of dilution genes; Equine coat color describes various colors in horses; Cream gene, describes the process for horses by which the cremello, perlino, smoky cream double-dilute colors are created as well as the buckskin, palomino and smoky black single ...
Some coat colors partially distinguished by unique patterning include: Bay: A horse coat color that features black point coloration on a red base coat. All bay horses have a black mane, tail and legs (except where overlain by white markings), caused by the presence of the agouti gene. Most have black hairs along the edges of their ears and on ...
