D)in ocean populations where genes can drift between individuals.

Question

Quizplus · Accepted Answer

Genetic drift occurs when there is a random change in the frequency of alleles in a population. This can happen when a large portion of the population is killed, regardless of their genetic makeup. This reduces the overall genetic diversity of the population and can result in certain alleles becoming more or less frequent just by chance. In smaller populations, this effect can be more pronounced, but larger populations are less susceptible to genetic drift. Therefore, option C is the best choice.
