Chapter 22, Problem 26P

Assume that the flower population described in the previous problem undergoes a different pattern of predation. Flower color determination and the starting frequencies of ${\text{C}}_1$ and ${\text{C}}_{\text{2}}$ are as described above, but the new insects attack yellow and red flowers, not orange flowers. As a result of the predation pattern, the relative fitness values are ${\text{C}}_{\text{1}}{\text{C}}_{\text{1}}\text{=0}\text{.40}$, ${\text{C}}_{\text{1}}{\text{C}}_2\text{=1}\text{.0}$, and ${\text{C}}_2{\text{C}}_2\text{=0}\text{.80}$.

a. What are the allele frequencies after one generation of natural selection?

b. What are the genotype frequencies among the progeny of predation survivors?

c. What are the equilibrium allele frequencies in the predation environment?
