Buckskin results from a single copy of the cream dilution gene acting on a bay or brown base coat. Buckskin is a horse coat color characterized by a tan or golden body with black points, including the mane, tail, and lower legs. The shade of the body coat can vary from light sandy tan to a deeper golden color. Buckskins should not be confused with dun horses, as the dun gene does not occur in the Thoroughbred breed. The cream gene is inherited in an incompletely dominant manner. A buckskin carries one copy of the cream gene and can pass it to about 50% of its offspring on average. When two single cream carriers are bred together, about 25% of foals inherit no copy of the gene, 50% inherit one copy, and 25% inherit two copies. Horses that inherit two copies of the cream gene are known as double cream dilutes—cremello, perlino, or smoky cream—which have very pale coats and typically blue eyes.
