The dun gene is a dilution gene that affects both red and black pigments in the coat color of a horse. The dun gene lightens most of the body while leaving the mane, tail, legs, and primitive markings the shade of the undiluted base coat color. A dun horse always has a dark dorsal stripe down the middle of its back, usually has a darker face ...
Some were non-dun with primitive markings, and non-dun 1 is one of the oldest coat color mutations, and has been found in remains from 42,700 years ago, along with dun. Non-dun 2, the version of the dun gene that most domestic horses have, is thought to be much more recent, possibly from after domestication. [3]
A dilution gene that produces what looks like point coloration, but from a completely different genetic mechanism is the dominant Dun gene, which dilutes the color of the body coat but not the points, including primitive markings—a dorsal stripe down the back and, less often, horizontal striping on the upper legs. On a bay base coat the dun ...
Zebra stripes are visible on the left back leg. The dun gene also produces light guard hairs in the mane and the tail. Grullo [1] (pronounced GREW-yo) [2] [a] or grulla is a color of horses in the dun family, characterized by tan-gray or mouse-colored hairs on the body, often with shoulder and dorsal stripes and black barring on the lower legs ...
Every dun horse has a dorsal stripe, and some dun horses also have additional primitive markings. Some non-dun horses may also show primitive markings, namely newborn foals and horses with the non-dun 1 gene. [1] [4] Primitive markings in horses are an example of atavism: preservation of or reversion to ancestral type.
Dun most commonly refers to: Dun gene, which produces a brownish-gray color (dun) in horses and other Equidae; Dun (fortification), an ancient or medieval fort;
Blue dun or grullo (also grulla, mouse dun) coloring is created by the dun gene acting on a black base coat, and is a coat color with a bluish cast and darker points. [13] Unlike blue roans, grullos are solid color and appear bluish due to low amounts of pigment in each hair, not interspersed white hairs. [ 14 ]
Buckskin occurs as a result of the cream dilution gene acting on a bay horse. Therefore, a buckskin has the Extension , or "black base coat" (E) gene, the agouti gene (A) gene (see bay for more on the agouti gene), which restricts the black base coat to the points, and one copy of the cream gene (CCr), which lightens the red/brown color of the ...
