You have collected a large (randomly mating) population of mosquito's. You find that 91% of individuals exhibit the dominant phenotype (caused by allele A) while only 9% of individuals exhibit the recessive phenotype (due to aa). The recessive aa mosquito's fly more slowly and tend to get eaten more frequently by predators. You release the population into a controlled environment in which 40% of the recessive individuals do not survive to adulthood.
(a) What are the frequencies of the A and a allele before introduction into the new environment? a = 0.3; A = 0.7
(b) What are the expected frequencies of the A and a allele after one generation in the new environment? A' = .7265; a' = 0.2745
