Biology definition of gene flow
WebGene flow is the transfer of alleles from one population to another population through immigration of individuals. 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 ... WebGenetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations. frequency, of other alleles.
