B)nonrandom mating
C)genetic drift
D)natural selection

Question

Quizplus · Accepted Answer

Genetic drift is a random fluctuation in allele frequencies in a population, which can result in the loss of alleles through chance events. This effect is more pronounced in smaller populations, as chance events have a greater impact on the small gene pool. Therefore, genetic drift most consistently requires a small population as a precondition for its occurrence.
