This, in plant species, can buffer against genetic erosion resulting from processes of endogamy and genetic drift. |
This is different than the traditional effective sizes, which are descriptions of the equilibrium behavior of genetic drift in the population. |
All evolutionists agree that genetic drift can't explain adaptive evolution. |
The relative importance of selection and genetic drift in the evolution of duplicated genes is under debate. |
The first alternative is that the long basal branches are simply the chance result of genetic drift in a large, panmictic ancestral population. |
This analysis suggested that the African population is close to equilibrium between mutational forces and genetic drift. |
