Question

Quizplus · Accepted Answer

Genetic drift is the phenomenon where chance events influence the frequency of alleles within a population, leading to random changes in gene frequencies. This occurs because not all individuals produce the same number of offspring, and therefore, not all alleles are equally represented in the next generation. As a result, genetic drift can cause the loss of certain alleles or the fixation of others, leading to a decrease in genetic diversity within a population.
