16 Φεβ 2024 · Gene flow, also called gene migration or allele flow, refers to the transfer of genetic material from one population to another during reproduction (through interbreeding) or the vertical transfer of genetic material from the parent to the offspring.
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.
17 Σεπ 2018 · 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.
31 Οκτ 2023 · gene flow: the transfer of alleles or genes from one population to another; mutation: any heritable change of the base-pair sequence of genetic material
Gene flow is the passage and establishment of genes typical of one population in the genepool of another by natural or artificial hybridization and backcrossing. In the drawing above, population Y has a higher frequency of allele a (q = 0.90).
6 Μαρ 2016 · Gene flow is a fundamental evolutionary force in adaptation that is especially important to understand as humans are rapidly changing both the natural environment and natural levels of gene...
Through gene flow, modern humans spreading across Eurasia from Africa could then acquire these alleles ‘for free’ at a frequency of a few percent, thus ensuring that they were not lost and...
