Assuming that the population was in Hardy-Weinberg equilibrium for the G locus, what percentage of moths in the natural population was white in 1962? a) 2% b) 4% c) 8% d) 20% e) 64%

Answer: b) 4%
Explanation: To determine the percentage of white moths, calculate the frequency of the recessive allele (g) and use q2 for the recessive phenotype. If the proportion of white moths (gg) is 4%, this means q2=0.04, so q=0.04​=0.2 and the frequency of the recessive allele is 0.2. The correct answer is 4%.
