D)genetic isolation
E)stabilizing selection

Question

Quizplus · Accepted Answer

Genetic drift refers to the random fluctuation of gene frequencies in small populations, which can lead to the loss or fixation of alleles. This can have a significant impact on the genetic diversity and adaptability of a population over time. Allelic separation, natural selection, genetic isolation, and stabilizing selection may also contribute to changes in gene frequencies, but they do not specifically refer to the effects of small population size on genetic drift.
