Explanation:
Detailed explanation-1: -The bottleneck effect occurs when only a few individuals survive and reduces variation in the gene pool of a population.
Detailed explanation-2: -Typically, genetic drift occurs in small populations, where infrequently occurring alleles face a greater chance of being lost. Once it begins, genetic drift will continue until the involved allele is either lost by a population or until it is the only allele present in a population at a particular locus.
