Question

which populations are most impacted by genetic drift? small populations large populations populations are not affected

Explanation:

Genetic drift is a random change in allele frequencies. In small populations, chance events can have a more significant impact on allele frequencies. For example, if a small number of individuals carry a particular allele, random deaths or non - reproduction can quickly remove that allele from the population. In large populations, such random changes are averaged out due to the large number of individuals.

Answer:

small populations
