In a very large population of butterflies the dominant allel

In a very large population of butterflies, the dominant allele for red spots is R. The recessive genotype (rr) has no red spots. Red spots on the wings briefly frighten bird predators, often allowing the butterfly with red spots to escape. The frequency for R in this population is 0.5. If these conditions continue which of the following should we expect in 15 years?

a.) the frequency of R will be less than 0.5

b.) the frequency of r will be 0

c.) the frequency of R will be 0

d.) the frequency of r will be less than 0.5

e.) the frequency of R will be equal to 0.5

Solution

The correct answer is :e) the frequency of R will be equal to 0.5

Reason: The above population is in accordance to Hardy weinberg equilibrium.So, the frequency of R will remain constant from one generation to the other i.e 0.5
