Genetic Drift random change in allele frequencies in a population from generation to generation due to finite population size. Mutation an error in the replication of DNA that causes a change in DNA sequence. Only source of new genetic variation in populations (sex cells only). Gene Flow (immigration or migration) exchange of genes among populations via migration of individuals. Processes that Determine Levels of Genetic Diversity in a Population
