Genetic Drift -- the role of finite population size - IB-USP
... This shows that the amount of evolutionary change associated with random sampling error is inversely related to population size; the larger the population, the less the allele frequency will change. Hence, genetic drift is most effective as an evolutionary force when N is small. The coin box simulat ...
