WebThe bottleneck effect is a type of genetic drift. Genetic drift is when the frequencies of alleles change in a population based on chance events. The change in frequency is totally random, and there is no pressure selecting for particular alleles. Genetic drift is different from natural selection, which is a process in which a population slowly ...
