Blue flower color (B allele)is dominant to white (b allele).If a population of plants contains white flowers (bb)at a frequency of 0.04,what is the frequency of the heterozygous genotype?

Question

Quizplus · Accepted Answer

Since the frequency of the homozygous recessive genotype (bb) is 0.04, the frequency of the dominant allele (B) in the population is sqrt(0.04) = 0.2. Thus, the frequency of the heterozygous genotype (Bb) can be calculated as 2pq = 2(0.2)(0.8) = 0.32 or 32%.
