Each of the following has a better chance of influencing gene frequencies in small populations than in large populations, but which one most consistently requires a small population as a precondition for its occurrence?

Question

Genetic drift is the random fluctuation of allele frequencies in a population due to chance events. This effect is more pronounced in small populations, where chance events can have a greater impact on the gene pool. Therefore, genetic drift consistently requires a small population as a precondition for its occurrence. While the other options can also have a greater impact on gene frequencies in small populations, they do not necessarily require a small population as a precondition.
