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?
 
 

Question 2

What is an X-linked inheritance pattern? Use a specific example to explain the role of the father and mother in this
  unique inheritance pattern and note the differential impact on male and female offspring. What will be an ideal response?

Answer to q. 1

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.

Answer to q. 2

In X linked inheritance patterns, X linked recessive traits are more common in males than
females. A color blind female must have a color blind father and a mother who is either
homozygous or heterozygous for the recessive allele for color blindness. Whereas a color
blind male need only have a mother who is heterozygous for color blindness.
