Question

3,4

In cats, the black (B) gene has three alleles that control the density of eumelanin
granules in the hair shaft. The B allele is dominant and produces a black coat.
The b allele reduces black to a dark brown, chocolate color in bb homozygotes.
The b' allele further reduces melanin density to produce a medium-brown coat in
homozygotes called cinnamon in homozygotes. b is dominant to b' so the
dominance hierarchy is B > b > b'.
A mating between black and chocolate cats yields kittens of all 3 coat colors
(black, chocolate and cinnamon). Use the dropdown menus to indicate parental
genotypes:
The genotype of the black parent was
genotype of the chocolate parent was
[Select]
[Select]
and the

Which of the 3 alleles of the B gene described in the previous question (B, b or
b') is most likely to contain a severely damaging mutation like an early frameshift
or nonsense mutation and why?

Expert Solution

Step 1: A part

The black parent (producing black kittens) can have the following genotypes:
- Homozygous dominant for the black allele (BB): This cat has a completely black coat.
- Heterozygous with one black allele and one brown allele (Bb): This cat has a black coat because the black allele (B) is dominant over the brown allele (b). However, it carries one copy of the brown allele, which can be passed on to offspring.
