The founder effect is an extreme example of "genetic drift." Genes occurring at a certain frequency in the larger population will occur at a different frequency -- more or less often -- in a ...

For example, if heterozygotes at a locus have ... In the absence of natural selection and genetic drift, gene flow leads to genetic homogeneity among demes within a metapopulation, such that ...

According to this hypothesis, most of the changes in DNA inside individuals are the result of "genetic drift" -- random changes that go on all the time and aren't steered by natural selection in ...

For example, genes associated with traits that ... meaning they later vanished due to genetic drift or were masked by extensive population mixing. This research provides an unprecedented view ...
