WebApr 11, 2024 · Founder effect can result in the smaller population that left the larger population to have less genetic diversity. And the way I look at this is, the arc of Africa migration 100,000 years ago created what is considered the original founder effect, in the sense of the small group of people that left Africa to populate the rest of the world … WebApr 7, 2024 · Genetic Drift vs Gene Flow Gene flow can be defined as the movement of genes between populations, species, or organisms. For eg., bacteria can transfer genes between different cells. On the other hand, genetic drift can be defined as the random selection of genes in a population.

WebApr 10, 2024 · Genetic drift is the change in frequency of an existing gene variant in the population due to random chance. Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It could also cause initially rare alleles to become much more frequent, and even fixed.
