Population bottlenecks occur when a population's size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population's genetic variation by a lot, even if the bottleneck doesn't last for very many generations.

We extend the well known bottleneck paths problem in two directions for directed graphs with unit edge costs and positive real edge capacities. Firstly we narrow the problem domain and compute the bottleneck of the entire network in O ( m log n) time, where m and n are the number of edges and vertices in the graph, respectively. sheriff fam on youtubeWebQ: Explain comprehensively the Bottleneck Effect and Founder’s Effect.
