A female black cat mated with an albino male and gave birth to 6 black kittens. When the albino male
was mated with a different female black cat, 3 black cats and 2 albino cats were produced. How can
you explain this genetic situation? Write genotypes for all three parental cats and offspring. What will be an ideal response?
Concepts to Consider: The first female black cat was homozygous dominant for the albinism gene.
The second female black cat was heterozygous. The albino male was homozygous recessive. All the
offspring from the first mating were heterozygous. In the second mating, the black offspring were
heterozygous, while the albinos were all recessive.
