Concept

Problem: In peas, a gene shows incomplete dominance for flower color such that RR = purple, Rr = pink, and r = white. In an isolated pea patch, a killing frost takes the population out of H/W equilibrium and leaves only 36 plants with white flowers, 7 with pink flowers, and 14 with purple flowers. What is the frequency of the recessive allele in the surviving population population?a. 0.31b. 0.69c. 0.63d. 0.60e. 0.37
