Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Genetic drift is more likely to be extremely impactful and change the allele frequencies in a population-
A
That has a low mutation rate
B
In which natural selection is occurring
C
That is very small
D
For which environmental conditions are changing
Explanation: 

Detailed explanation-1: -Small populations are more likely to experience genetic drift because allele frequencies are more likely to vary swiftly and substantially over a few generations or drift due to random events. Small populations might experience rapid change since each individual is different.

Detailed explanation-2: -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-3: -Genetic drift is change in allele frequencies in a population from generation to generation that occurs due to chance events. To be more exact, genetic drift is change due to “sampling error” in selecting the alleles for the next generation from the gene pool of the current generation.

Detailed explanation-4: -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-5: -The consequences of genetic drift are numerous. It leads to random changes in allele frequencies. Drift causes fixation of alleles through the loss of alleles or genotypes. Drift can lead to the fixation or loss of entire genotypes in clonal (asexual) organisms.
