Jerold Bell, adjunct professor of genetics at Cummings School of Veterinary Medicine at Tufts University in North Grafton, Massachusetts. This is the same chromosome that, along with Y in males, determine a cat’s sex, says Dr. The color genes for black and red in cats are contained within the X chromosome.

Thus, no color is associated with a particular sex, except in cats and hamsters.” “Since the genes for sex and hair colors are on different chromosomes, they are inherited independently of each other. “These other chromosomes contain genes that affect hair color, pattern, shape and length,” Grahn says. Robert Grahn, a forensic analyst at the veterinary genetics laboratory at the University of California in Davis. But a number of additional chromosomes are present and vary depending upon species, says Dr. As you may recall from high school biology, mammals have two chromosomes that determine their sex-XX for females and XY for males.
