to be extinct
Bottleneck effect refers to the reduction of a population’s gene pool and the accompanying changes in gene frequency produced when a few members survive the widespread elimination of a species.
The black footed ferrets underwent a bottleneck effect resulting in the last wild population site of ferrets to be discovered in Meeteetse, Wyoming 1981.
About 25% of the original 19 founders’ genes have made it into the current population.
