WebApr 24, 2024 · Gene flow differs from genetic drift because it is the transfer of alleles or gametes from one population to another. It happens when a population migrates or becomes geographically isolated. This is different from the genetic drift seen with the founder effect where the new group is formed in an area that does not have an existing … WebHow does gene flow cause evolution? interbreeding between different populations brings new alleles How does non-random mating cause evolution? there would be no selection or change to the population How does genetic drift cause evolution? change in allele frequency in a population How does selection cause evolution?

WebGene flow is a fundamental agent of evolution based on the dispersal of genes between populations of a species. It involves the active or passive movement of individual plants, animals, gametes, or seeds. Gene flow involves not just dispersal but also the successful establishment of the immigrant genotypes in the new population.

In human populations, … WebMay 30, 2024 · Gene flow is a significant barrier to speciation; where gene flow is frequent between populations and the gene pools are regularly shuffled, the two populations do not have an opportunity to become genetically distinct. Gene flow can also increase the genetic diversity of a population. banangan view deck
