Suppose that rabbit fur color is controlled by one gene with two alleles with incomplete dominance. BB individuals are black, Bb individuals are gray, and bb individuals are white. A population has 15 black rabbits, 30 gray rabbits, and 55 white rabbits. Is this population evolving at the fur color locus? A. Yes, the population is evolving 36. B. No, the population is in HWE C. It depends on whether fur color affects fitness

Answer:

The correct answer is A.

Explanation:

Yes, the population is evolving. On the basis of incomplete dominance, the phenotypic ratio should be 1: 2: 1. However, in this population, the Grey rabbits are less in comparison to the population of white rabbits. This shows that there is a gradual evolution at the fur color locus.  

Option B is incorrect, as according to HWE, the genetic frequencies and alleles should be the same in the absence of any evolutionary influences. However, in the given case, evolution is affecting the population. Thus, it is not applicable.  

Option C is also incorrect, as white color is not appropriate for escaping from predators than Grey and black. So, it is also not applicable.
