17 wrz 2018 · Gene flow is the exchange of alleles between two or more populations, often through migration or artificial selection. Learn how gene flow affects the diversity and evolution of different organisms, such as dogs, birds, and bacteria, with examples and a quiz.
16 lut 2024 · Gene flow is the transfer of genetic material between populations or species, which changes the gene pool and increases genetic variation. Learn how gene flow occurs, what factors affect it, and see examples from nature and human populations.
The genetic variation in modern human populations has been critically shaped by gene flow. For example, by sequencing ancient DNA, researchers have reconstructed the entire Neanderthal genome – and they’ve found that many snippets of these archaic sequences live on in modern humans.
In population genetics, gene flow (also known as migration 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 population.
Gene flow, the introduction of genetic material (by interbreeding) from one population of a species to another, thereby changing the composition of the gene pool of the receiving population. The introduction of new alleles through gene flow increases variability within the population.
Our overview of Gene Flow curates a series of relevant extracts and key research examples on this topic from our catalog of academic textbooks.
Learn how species exchange genes with each other and how gene flow can generate or limit biodiversity. Explore examples of hybridization and gene flow in plants, animals and humans.
