Assuming that the population was in Hardy-Weinberg equilibrium for the G locus, what was the frequency of allele G in the gray moths that emerged in 1980? a) 0.33 b) 0.50 c) 0.67 d) 0.75 e) 1.00

Answer: c) 0.67
Explanation: Given that the population is in Hardy-Weinberg equilibrium, the frequency of allele G can be determined directly from the frequency of the gray moths. If the gray moths include both GG and Gg, the frequency of the dominant allele G can be calculated using allele frequency formulas and equilibrium principles. For typical scenarios, this value is usually around 0.67.
