Random Mechanisms of Evolution

Random Mechanisms of Evolution. Genetic Drift. Change in allele frequency due to chance Occurs in small populations Example: Founder Effect, Bottleneck. Gene Flow ( Migration ). Change in allele frequency as individuals from one population are incorporated into another. Mutation.
