WebSep 17, 2024 · Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from … WebGene flow is the process of alleles going from one population to another while genetic drift is the alteration of allele frequency in a gene pool. The cause of gene flow is migration or geographical isolation while that of genetic drift is random sampling with two mechanisms (bottle effect and founder effect).
WebApr 1, 2002 · Genetic drift is defined as random changes in allele frequencies in a population. The mechanism is so named because the pattern shows the drift of allele frequencies, up and down over time—there is no predictable directional component to change from generation to generation.
