Question

Quizplus · Accepted Answer

Cats do not have a Y chromosome; they have two X chromosomes in females and one X and one Y chromosome in males. The calico coloration is a result of X-linked inheritance, where the orange color is on one X chromosome and the black color is on the other X chromosome. The presence of white color is determined by another gene that blocks all pigment production. Calico coloration is rare in males because they only have one X chromosome, and therefore cannot have both the orange and black color genes expressed.
