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 ...

But they did not detect any genes that conferred salt tolerance on the fish, for example. "This divergence appears to have been primarily driven by high levels of genetic drift just over the last ...

For example, Mendelian inheritance predicts that ... codes to strain names can give a general indication of whether genetic drift has occurred in one substrain versus another.

Population bottlenecks imply a reduction in effective population size, the increase of sample variance across generations, that is, random genetic drift. As population size ... and additive ones as ...

For example, genetic drift describes the many stochastic fluctuations inherent to evolution. In large populations, natural selection may act more efficently in purging deleterious variation and ...

During the Industrial Revolution, for example, peppered moths changed from ... to the vagaries of history — a process called genetic drift. It can be challenging to determine if a common ...
