Question

Quizplus · Accepted Answer

Both a bottleneck and a founder effect result in a decrease in the genetic diversity of a population. In a bottleneck event, the population size is drastically reduced, and only a few individuals survive to reproduce, leading to a loss of genetic variation. In a founder effect, a small group of individuals separates from the larger population and establishes a new population, again leading to reduced genetic diversity due to the limited genetic makeup of the founding individuals.
