Novay_Z [31]3 years ago

Genetic drift occurs when there is no random mating across a population. This causes a change in allelic frequency due to a random sampling of the population.

As the aboriginal population explored the earth,  a small part of the population became geographically isolated either due to continental drift and climate changes. As the isolated population grew bigger, they established their own gene pool. This resulted a change in genotypic frequencies from that of the aboriginal population.
