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 ...

In this population we assume there is random mating and sexual reproduction without normal evolutionary forces such as mutation, natural selection, or genetic drift. In the absence of these ...
