File:Population bottleneck.jpg

Summary

Description
English: Representation of a population bottleneck. Colored balls represent the alleles present in the population. The population numbers 500 initially, but within five years the size of the population has dwindled to 50, and within ten years to just ten. As a consequence of the population bottleneck, there has been a random drift in the allele frequency distribution, and a loss of two of the original five alleles.
