Researchers examined historical portraits of these monarchs to study their unusual facial quirks and trace familial ties ...

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 ...

As Gautschi et al. explain, genetic drift, arguably the most powerful evolutionary force at work in small populations, results from the random sampling of alleles from one generation to the next ...

Graham Coop, professor of evolution and ecology and director of the Center for Population Biology, has been elected to ...

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 ...
