Detailed explanation-1: -Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error (i.e., genetic drift). This is because some versions of a gene can be lost due to random chance, and this is more likely to occur when populations are small.

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 is the only allele present at a particular gene locus within a population.

Detailed explanation-3: -Answer and Explanation: The correct answer is (a) small population. Genetic drift occurs when random events change the allele frequencies in a population. This is most likely to occur in small populations, where small random changes in allele frequencies can have a significant effect on the population as a whole.
