Question

Quizplus · Accepted Answer

Genetic drift occurs when a random event results in a change in the frequency of alleles in a population. In small populations, these random events can have a larger impact on the overall genetic makeup of the population, as there are fewer individuals to contribute to the gene pool. In larger populations, the effects of genetic drift are relatively minor as the random events tend to even out over time with a larger sample size. Therefore, genetic drift has a greater influence on small populations.
