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

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:))
