How could genetic drift explain differences in the genotype frequencies among the caucasian and aborigine populations?

Biology

Novay_Z [31]4 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.

-This is what happens at the mid-oceanic ridge where a divergent boundary is causing two plates to move away from one another resulting in spreading of the sea floor. As the plates move apart, new material wells up and cools onto the edge of the plates.
