Phenomenon occurring when a population is greatly reduced over at least one generation. The low number of remaining breeders therefore transmits only a fraction of the initial genetic diversity to subsequent generations. This results in a genetic impoverishment of the population.

In conjunction with the founder effect, bottlenecks are one of the mechanisms of species evolution.
