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.
Founder effects. A founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have: 1  reduced genetic variation from the original population. 2  a non-random sample of the genes in the original population.ottlenecks and Founder Effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a populations size is reduced for at least one generation.
