Genetic drift is one of the four main factors associated with changes in the gene pool over time. Other factors that lead to ...

Aa Aa Aa Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population ...

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 ...

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 ...

Additionally, ancient adaptation signals can be masked by genetic drift—random fluctuations in the frequency that genes appear—and population mixing, which causes certain adaptive traits to ...

A genomic study encompassing more than 300 genomes spanning the last 50,000 years has revealed how a single wave of Neandertal gene flow into early modern humans left an indelible mark on human ...

Luke is a quantitative geneticist interested in complex trait architecture, and how evolutionary forces such as genetic drift and selection shape that architecture. Starting out in population genetics ...
