Population bottleneck effect

WebThe bottleneck effect refers to the way in which a reduction and subsequent increase in a population’s size affects the distribution of genetic variation among its individuals. … A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as specicide, widespread violence or intentional culling, and human population planning. Such events can reduce the variation in the gene pool of a population; thereafter, a smaller popul…
