In a population of flowers growing in a meadow, C1 and C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with f(C1)= 0.8 and f(C2)= 0.2. Flowers that are C1C1 are yellow, orange flowers are C1C2, and red flowers are C2C2. A storm blows a new species of hungry insects into the meadow, and they being to eat the yellow and orange flowers, but not the red. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1 = 0.30, C1C2 = 0.60, and C2C2= 1.0.
a. Assuming the population begins in H-W equilibrium, what are the allele frequencies after one generation of natural selection?
b. Assuming random mating takes place among survivors, what are the genotype frequencies in the second generation?
c. if predation continues, what are the allele frequencies when the second generation mates?
d. what are the equilibrium frequencies of C1 and C2 if predation continues?
