There are two types of genetic drift: Bottleneck and Founder effect . Both population bottlenecks and founder events have similar effects: they reduce the amount of genetic diversity in a population . Some genes are eliminated from the population, while others that may originally have been rare, now become common. The important similarity between founder events and population bottlenecks is their randomness . In natural selection, the genes with the best survival qualities are the ones that get passed on to the next generation. In a founder event or a population bottleneck, the genes that get passed on are not any better than the ones that got eliminated and they were just preferred by chance .
