The gene for coat color in some breeds of cats is found on the X chromosome. Calico cats are mottled with orange and black colorings. What is a possible explanation for the fact that true calico cats are only female?
(A) The allele for coat color is randomly chosen by X-inactivation.
(B) The coat color is linked with genes that are lethal to male cats, so male calico cats never live past birth.
(C) Coat orange and black color is expressed only in female cats; males have only one color.
(D) Male cats have Y chromosomes.
