Vedclass · Answer

(B) Genetic drift refers to the change in the frequency of an existing gene variant (allele) in a population due to random sampling of organisms. It is a significant evolutionary force in small populations where chance events can drastically alter allele frequencies. In large populations,the effect of genetic drift is negligible because the random fluctuations in allele frequencies tend to cancel each other out,making the population more stable. Therefore,genetic drift does not significantly apply to large populations.
