Question

Quizplus · Accepted Answer

Genetic drift refers to random fluctuations in allele frequencies due to chance events, and it can have a greater impact on smaller populations as chance events can have a greater influence on the population. Therefore, as population size decreases, the influence of genetic drift on allele frequencies increases.
