WebGene Flow The movement of alleles from one population to another. Genetic Drift Changes in allele frequency that are due to chance. Bottleneck Effect Genetic drift that occurs after an event greatly reduces the size of the population. Founder Effect Genetic drift that occurs after a small number of individuals colonize a new area. Sexual Selection WebClines are often cited to be the result of two opposing drivers: selection and gene flow (also known as migration). Selection causes adaptation to the local environment, resulting in different genotypes or phenotypes being favoured in different environments. This diversifying force is countered by gene flow, which has a homogenising effect on populations and …
