Answer:
Gene pool of the population at Hardy-Weinberg Equilibrium remain constant over time.
Step-by-step explanation:
According to the Hardy Weinberg principle, the allele and genotype frequencies in a population remain constant in absence of factors of evolution. Here, the population should be randomly mating to be at Hardy-Weinberg Equilibrium. Since the moth population is at Hardy-Weinberg Equilibrium, it should have constant allele frequencies from one generation to next.
