Question

In a population of squirrels, the allele that causes bushy tails (B) is dominant, while the allele that causes bald tails is recessive (b). If 64% of the squirrels have a bushy tail, what is the frequency of the dominant allele?A. 0.8B. 0.6C. 0.4D. 0.36E. 0.2

Answer 1

Answer: C. 0.4

64% of the population have dominant phenotype which means they’re either BB or Bb. The other 36% of the population have bb genotype. If this population is in equilibrium then f(b)=rad0.36=0.6 and as u know f(b)+f(B)=1. So 1-0.6=0.4.

Hope this helps:))
