Dexter Cow Colours
Dexter cattle occur in three different colors: black, red, and dun. Two pairs of genes that are located on separate chromosomes control these colors. Cattle chromosome 8 contains the B (brown = Dexter dun aka TYRP1) locus Cattle chromosome 18 contains the E (extension = red aka MC1R) locus Black and red is one pair of alternative colors.
In Dexter cattle, there are two different red genes. The. However, since other genes are involved with the color of the nose/eyeliner, and the darkness of the coat, there are exceptions, and you cannot be sure of the animal's red genotype without a test, (which is available at virtually any laboratory doing cattle genetic testing).

Later a third colour, dun, was accepted into the breed. The colour Dun was accepted into the breed in the seventies. Dun is widely believed to have come into the breed through introgression of non Dexter blood into the breed.
Dexters can be solid red, black, or dun. They do not have spots, but some white on the tail and the underside of the belly behind the navel is common. White, as a body color, is not a true Dexter color.
Some people do bred Dexters to other breeds of cattle to produce boutique colors and color patterns, but true, heritage Dexters are only red, black, or dun. Dexter Colors In purebred Dexters, the color of the coat should be red (varying shades including wild-type), black, dun, or brindle which is the most rare of all Dexter colors. As of this writing, we do not have a dun or brindle Dexter here at Mountain Heritage Farm.
Perhaps you've heard of or seen "White Dexters"? In the case of Dexter coloration, we will consider our baseline color to be black. There are two completely separate genes that will make Dexters a color other than black. In both cases, these colors are recessive to black, so the animal must receive the same non.
