The gene for black fur sits on an X chromosome the gene for orange fur also resides on an X chromosome, but not the same one. Other colors are modifications of the two basic colors for example, gray is the dilute version of black. The two basic colors are black and orange, sometimes called red. Males have one X and one Y chromosome and are called XY.Īpproximately 20 genes determine coat color in cats. Females have two X chromosomes and are referred to as XX.
