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 one population to another, they must interbreed with the new population for gene flow to occur. WebThe transmission of genes from one group to another is known as gene flow. Gene transfer is the exchange of genes between two organisms. The development of a new species is enabled via gene transfer. The fluctuation of allele frequencies in a small population is known as genetic drift.
