When there is low genetic variation in a population the species produced are unlikely to withstand diseases.
decrease in frequency from one generation to the next
A population bottleneck (or genetic bottleneck) is an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing. This reduces the genetic diversity of the population, and even if the population bounces back in size, it can often show evidence of the past bottleneck by lacking significant variation for its size. A good example is that of the cheetah, whose current population shows almost negligible variation. Humans are not currently experiencing any genetic bottlenecking because the population is increasing. However, there is evidence suggesting that the human population underwent one or more bottlenecks in the past, since its overall genetic diversity is relatively low for its size.
