"The orange locus in cats is located on the X chromosome. In females, XoXo results in orange cats and X+X+ results in black cats When a female is heterozygous XoX+, they express both colors in patches due to a phenomenon called X-inactivation in which one X in every cell is inactivated. These females are called calico or tortoiseshell, depending on the presence of white spots. Male cats are either orange (XoY) or black (X+Y). A cross between a black female...
