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.

12 wrz 2024 · Gene flow is the transfer of genetic information from one population to another. Also known as gene transfer or gene migration, it plays a crucial role in the evolution and adaptation of species. Understanding the dynamics of gene flow is essential to assess the potential risks and benefits of gene drive approaches.
Here, we develop theory and simulations to show how the effect of gene flow can be accounted for using an admixture model from a known set of sources to recover the genome-wide contribution of gene flow and linked selection.
16 lip 2016 · Gene flow, the successful transfer of alleles from one population to another, is now known to vary considerably among species, populations, and individuals as well as over time. It frequently occurs at rates sufficient to play an important evolutionary role for populations of both animals and plants (Ellstrand 2014 ; Yakimowski and Rieseberg ...
In the last half century, gene flow has moved from relative obscurity to a well‐recognized component of evolution. Gene flow, the successful transfer of alleles from one population to another, is now known to vary considerably among species, populations, and individuals as well as over time.
6 mar 2016 · Gene flow can even enhance adaptation by augmenting genetic variation, especially if selection is spatially and/or temporally variable. Understanding how adaptation with gene flow occurs can help predict how organisms will cope with ongoing and future environmental change.
