Gene flow best describes the evolutionary process at work.
Gene migration is another name for gene movement. The transfer of genetic material from one group to another is referred to as gene flow.
Through migration, gene flow can occur between two populations of the same species and is mediated via vertical gene transmission from parent to offspring and reproduction.
The transfer of genes from one group to another is known as gene flow or gene migration.
The interbreeding of Homo sapiens with Neanderthals in Europe, which produced Neanderthal genes in contemporary Europeans, is an illustration of gene flow.
Pollination is an example of gene flow in plants. Gene flow, also known as gene migration, is the transfer of genetic material from one population of a species to another by interbreeding, modifying the species' gene pool.
