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 ...

Genetic drift is common after a population experiences ... rarely has the same genetic makeup over its entire range. For example, individuals in a population living at one end of the range may ...

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 ...
