Als Gendrift (genetische Drift; das niederdeutsche Wort Drift ist verwandt mit dem deutschen treiben, auch Alleldrift oder Sewall-Wright-Effekt genannt) bezeichnet man in der Populationsgenetik eine zufällige Veränderung der Allelfrequenz innerhalb des Genpools einer Population.
Sewall Wright was the first to attach this significance to random drift and small, newly isolated populations with his shifting balance theory of speciation. Following after Wright, Ernst Mayr created many persuasive models to show that the decline in genetic variation and small population size following the founder effect were ...
