Unformatted text preview: bottleneck, but in a different manner. The genetic bottleneck consists of a population drop in size caused by a specific event like a volcano erupting etc. When this happens, many of the alleles may in fact become lost forever. This makes it impossible to find the same amount of variation in this population, because no matter how large the population amounts to over time with reproduction, it can phase out what was left of the allele. As we have studied, lack of genetic diversity can lead to an inability to adapt and survive in an environment. As a result of these forms of genetic drift, we can surely see issues relating to adaptation, which can often lead to extinction....
