Question

Quizplus · Accepted Answer

The frequency increase of dark phenotypes in response to increased pollution is called industrial melanism. This is because the increased pollution leads to a higher concentration of melanin, resulting in darker individuals being better adapted to the environment. Genetic drift and founder effect refer to random events that can alter the gene pool of a population, while assortative mating and stabilizing selection are not directly related to the phenomenon of industrial melanism.
