Population bottleneck followed by recovery or extinction. A population bottleneck (or genetic bottleneck) is a sharp reduction in the size of a population due to environmental events (such as earthquakes, floods, fires, disease, or droughts) or human activities (such as genocide).n consequence of such population size reductions and the loss of genetic variation, the robustness of the population is reduced and its ability to survive selecting environmental changes, like climate change or a shift in available resources, is reduced.
In the study of genetics, a population bottleneck is an event in which the gene pool of an existing population of organisms experiences a drastic reduction of diversity, and a change in the distribution of alleles.Various mechanisms can lead to a population bottleneck.edit] Founder effect. The founder effect is a special case of a bottleneck, where a small subset of a population founds a new population, having migrated to a new area, e.g. an island on the coast. The key features of this particular variety of bottleneck are the new location and that the original population survives.
