1. Some breeds of cats have fur color that is greatly determined by a
pair of codominant alleles that are sex-linked. Black fur is produced
by the allele B, and the allele B' produces an orange coat. When both
alleles are present in heterozygotes, a calico or tortoiseshell pattern
is produced. A black cat has a litter of seven kittens- 4 black cats and
3 calicos.
