Question

An epistatic allele in labrador retrievers ensures that ee lab pups are yellow. Two other alleles control coat color, where black is dominant to brown. What portion of yellow pups would you expect from a parental cross where one parent was yellow (Bbee) and the other was heterozygous

Answer 1

Answer:

1/4

Explanation:

Epistasis is defined as a phenomenon in a genetics where the effect of the gene mutation which dependent on the absence or the presence of the mutation in more than one genes.

In the context, an epistatic allele in the Labrador retrievers which ensures the ee lab pups that are yellow and the two other alleles which control coat color are black that is dominant to the brown.

Thus, 1/4 portion of the yellow pups would expect from the parental cross where one of the parent is yellow (Bbee) and the other is heterozygous.

Thus the answer is 1/4.
