When a population size drops rapidly over a short period, causing a loss of many alleles that were present in the larger ancestral population, this is referred to as the effect.

A type of genetic drift in which a population's size drops rapidly over a short period of time, causing the loss of many alleles, is called aMultiple choice question.bottleneck effect.polygenic effect.founder effect.migration effect.
