How does genetic drift affect the hardy-weinberg equilibrium?

Due to the high number law, which states that allelic frequencies equal the likelihood of selecting a specific allele, genetic drift is the random variation of allelic frequencies over generations. It is observed in smaller populations rather than larger ones.

However, genetic drift is prevented in the Hardy-Weinberg equilibrium because there is an infinite population and number of individuals.

Thus, there is no effect of genetic drift on the Hardy-Weinberg equilibrium.

Genetic drift can disrupt the Hardy-Weinberg equilibrium by causing random changes in allele frequencies within a population. This occurs more significantly in smaller populations where chance events have a greater impact. As a result, genetic drift can lead to deviations from the expected genotype frequencies predicted by the Hardy-Weinberg equilibrium.
