Coat color in cats is a codominant trait and is located on the X chromosome. Cats can be black, orange, or calico. A calico cat has black and orange splotches. In order to be calico, the cat must have an allele for the black color as well as an allele for the orange color. Also located on the X chromosome of a cat is a gene that codes for deafness. The gene is recessive. A black female cat that is heterozygous for deafness (Dd) is crossed with a male orange cat that is not deaf. Show the cross. What are the phenotypes of the offspring and in what proportion? (Hint: Place two superscript letters on the X chromosome in your cross.)
