In a population of flowers growing in a meadow, C1C1 and C2C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with ff (C1)(C1) = 0.8 and ff (C2)(C2) = 0.2. Flowers that are C1C1C1C1 are yellow, orange flowers are C1C2C1C2, and C2C2C2C2 flowers are red. A storm blows a new species of hungry insects into the meadow, and they begin to eat yellow and orange flowers but not red flowers. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1C1C1 = 0.30, C1C2C1C2 = 0.60, and C2C2C2C2 = 1.0. A. Assuming the population begins in H−WH−W equilibrium, what is C1C1 allele frequency after one generation of natural selection? B.Assuming the population begins in H−WH−W equilibrium, what is C2C2 allele frequency after one generation of natural selection?
