The founder's EffectThe Founder's Effect is an example of genetic drift in which a few individuals become isolated from their original population. These isolated individuals create a new population and the allele frequencies/gene pool differs from the original population.
An example would be scientists taking four beetles from a large population and setting them in a new environment. They essentially founded a new population. |
Above is a humorous, yet informative, explanation of the Founder's and Bottleneck Effect.
