D)a sudden change in the environment that reduces the size of the population

Question

Quizplus · Accepted Answer

The founder effect occurs when a few individuals become isolated from a larger population and their gene pool differs from that source population. This can happen when a small group of individuals migrate to a new location, or when a subset of a larger population becomes geographically isolated. The genetic diversity of the new population will be reduced, and rare alleles may become more common due to chance events. Over time, the population can evolve independently from the source population, leading to the development of new species or sub-species.
