In cattle, the allele for red coat color (R) shows incomplete dominance over the allele for white (R’) coat color. The hybrid (RR’) is roan coat color, which is a mixture of red and white hairs. In a population of cattle, 32 percent of the population is roan color. What are the frequencies of the allele for red coat color (R) and white coat color (R’)? Assume that the conditions of Hardy-Weinberg equilibrium apply to the population.
A) R = 0.65; R’ = 0.35
B) R = 0.50; R’ = 0.50
C) R = 0.80; R’ = 0.20
D) R = 0.75; R’ = 0.25
