WebJul 14, 2024 · A bottleneck and a founder effect cause genetic variation to decrease due to genetic drift. A bottleneck effect impacts the original population and is a random sampling of the genes. A founder effect does not impact the original population since a few individuals leave and colonize a new area. Author. Recent Posts. WebApr 7, 2024 · Founder Effect (Image will be uploaded soon) In the founder effect, a new population is founded in a new location due to physical or geographical barriers. The new population formed does not interact and mate with the original population. As a result, the allelic frequencies of the new population will be different from the original population.
