All red, because it is the natural color

All black, because all red alleles would mutate to black

Suppose you have a population of flour beetles with 1,000 individuals. Normally the beetles are red; however, this population is polymorphic for a mutant autosomal body color, black, designated by bb. Red is dominant to black, so BB and Bb genotypes are red. Assume the population is at Hardy–Weinberg equilibrium, with equal frequencies of the two alleles. What would be the expected frequencies of the homozygous dominant, heterozygous, and homozygous recessive (in that order) after 100 generations, assuming that no selection or other evolutionary processes are operating?

Explanation / Answer

B) .25; 0.5; 0.25 is the answer.

Using the Hardy–Weinberg equilibrium and solving the equation p2 + 2pq + q2 = 1 where AA= p2 aa= q2 Aa= 2pq and since p= .5 and q=0.5 slving we get  .25; 0.5; 0.25 respectively.

Therefore B) .25; 0.5; 0.25 is the answer.
