[QUOTE="cowpunk'd, post: 536937, member: 1265"] A buckskin is a bay with a creme gene. Bay is caused by a modifier called agouti on a black based horse. A black horse can be homozygous black, carrying only black (plus agouti and creme in the case of a buckskin) or it is heterozygous black, one black and one red. Black is dominant over red and agouti modifies black to bay but has no effect on red (it can still be there, you just don't see it on a red horse). If the stallion is homozygous black he will never produce a chestnut foal even if bred to a chestnut mare. [/QUOTE]
