D) Gene flow
E) Bottlenecks

Quizplus · Accepted Answer

The founder effect occurs when a new population is established by a small number of individuals from a larger population. This can lead to a reduction in genetic diversity in the new population compared to the original population due to the small size of the founding group and the random genetic makeup of the founders. Therefore, A describes a reduction in genetic diversity when a new population is established by migrants. B, D, and E are also mechanisms that can influence genetic diversity, but they do not specifically describe a reduction in genetic diversity when a new population is established by migrants. Inbreeding, on the other hand, can occur in a new population established by migrants, but it does not necessarily result in a reduction of genetic diversity.
