What is Population bottleneck?
A '''genetic bottleneck''' occurs when many individuals of a [[species]] are killed (or die) because of a natural event, such as a [[famine]] or a [[disease]]. The phenomenon is also called '''population bottleneck'''.The result of this, is that the gene pool will be smaller, and the genetic diversity will also be smaller, in future generations. This can have effects, such as an [[inbreeding depression]]. [[Category:Ecology]]
