Definition of genetic drift in English: genetic driftnoun mass nounBiology Variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce. Example sentencesExamples - The first alternative is that the long basal branches are simply the chance result of genetic drift in a large, panmictic ancestral population.
- Rare and endangered species are susceptible to loss of genetic variation through genetic drift in small populations.
- The relative importance of selection and genetic drift in the evolution of duplicated genes is under debate.
- This is different than the traditional effective sizes, which are descriptions of the equilibrium behavior of genetic drift in the population.
- In the absence of selection, these values reflect divergence in allele frequencies due to genetic drift.
