D) founder effect

Question

Quizplus · Accepted Answer

The loss of diversity in a reduced population is called the bottleneck effect. This occurs when a population experiences a drastic reduction in size, leading to a decrease in genetic variation due to the random elimination of certain traits. Gene flow refers to the movement of genes from one population to another, and genetic drift refers to the random fluctuations in allele frequencies in a population. The founder effect occurs when a small group of individuals colonizes a new area, leading to a decrease in genetic diversity due to the limited number of founding individuals.
