Problem: A population of 100 moths has a gene that codes for wing color. Gray wings (G) are dominant to white wings (g). In this population, 20 percent of individuals are homozygous dominant for the trait, 20 percent are heterozygous, and 60 percent are homozygous recessive. Calculate allele frequencies for this population. State whether the population is in Hardy-Weinberg equilibrium, and justify your answer.
