Question

Quizplus · Accepted Answer

Both a genetic bottleneck and a founder effect result in a decrease in a population's genetic diversity. This occurs because both scenarios involve a significant reduction in the size of the population, either through a drastic reduction in numbers (bottleneck) or the establishment of a new population by a small number of individuals from a larger population (founder effect), leading to a reduced genetic variation in the new population.
