Question

The coloration of calico cats is also the result of the inactivation of one of a female cat's sex chromosomes. In females, two X chromosomes are present in all cells but only one is active, the inactive one is called a BARR BODY. This is why the coat color is random, even among cloned calico cats that have identical genomes. Calico is a coat color found in cats, which is caused by a SEX-LINKED, CODOMINANT allele.

KEY:

B = Black

R = Orange

BR = Calico

The following genotypes are possible;

Female cats can be black XBXB, orange XRXR, or calico XBXR
Male cats can be black XBY or orange XRY

If you are a cat breeder, what type of parents should you choose to have the MOST number of calico kittens?
