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 ...

The bottleneck effect may be a lingering threat for them ... As Gautschi et al. explain, genetic drift, arguably the most powerful evolutionary force at work in small populations, results from ...

which has led to the hypothesis that genetic drift plays a role in the evolution of new species. How does the physical distribution of individuals affect a population? A species with a broad ...

This variability may be part of a bet-hedging strategy, where populations express a range of phenotypes to ensure survival in unpredictable environments. In addition phenotypic variability between ...

Genetic drift is the term used in population genetics to refer to the statistical drift over time of gene frequencies in a population due to random sampling effects in the formation of successive ...

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

That is, changes affect the "letters" (four different types ... most of the changes in DNA inside individuals are the result of "genetic drift" -- random changes that go on all the time and ...

Such elevated risk is likely to be the consequence of genetic isolation. When members of a small population overwhelmingly ...
