In population genetics, gene flow (also known as gene migration or geneflow and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective … Se mer The level of gene flow among populations can be estimated by observing the dispersal of individuals and recording their reproductive success.
