Question

2 dark moths were released into either a clean forest (b) or a polluted forest (a). a sample of dark moths were recaptured every generation for five generations. the results can be seen in the graph below. which of the following statements is correct? multiple choice

Explanation:

In a polluted forest (A), the number of dark moths is increasing over generations, likely due to natural selection as dark - colored moths have a survival advantage against predators in polluted environments where surfaces are darker. In a clean forest (B), the dark - moth population is decreasing as they are more visible to predators. Genetic drift is a random change in allele frequencies and not applicable here as the change is directional based on environmental selection. For Hardy - Weinberg equilibrium, there should be no selection, no mutation, no migration, large population size, and random mating, which is not the case here. The moths in forest B are not migrating genes as there is no indication of gene flow between the two forests. The moths in forest A are experiencing natural selection, which is a form of reproductive success as the fitter (dark - colored) moths are more likely to survive and reproduce.

Answer:

The moth population in forest A are experiencing reproductive success.
