Question

Epistasis is observed when the allele of one gene masks the effects of another gene. Use the Punnett square to answer the question.What color would a dog's fur be if its genes are aabb?(1 point)Responseswhitewhitebrownbrownyellowyellowblackblack

Answer 1

To determine the fur color of a dog with the genotype **aabb**, we need to understand how the alleles interact. However, the specific genotype "aabb" alone doesn't indicate the fur color without knowing what the alleles "A" and "B" represent in terms of color.

Typically, in genetics involving fur color in dogs, we can see different interactions between dominant and recessive alleles. Here's a common scenario:

1. Suppose "A" (dominant) is associated with black fur and "a" (recessive) with brown fur.
2. Suppose "B" (dominant) is associated with yellow fur and "b" (recessive) with white fur.

In combination:
- If a dog inherits "aa", it may express brown fur instead of black.
- If a dog inherits "bb", it may express white fur instead of yellow.

The genotype "aabb" means the dog has two recessive alleles for both genes, which typically results in a dog having the traits that are linked to those recessive alleles.

If we assume that "aa" leads to brown fur and "bb" to white fur, the presence of "aabb" suggests that the dog would be **white**, assuming that b is recessive to the alleles for color.

So, the answer is:

**White**
