Respuesta :
Compared to the pre bottleneck population, the post bottleneck population has reduced genetic diversity. The population underwent stabilizing selection as a result of the bottleneck. Compared to the pre bottleneck population, the post bottleneck population has a lower risk of going extinct.
A bottleneck exposed the population to stabilizing selection, which resulted in a higher level of genetic variation in the post bottleneck population than in the pre bottleneck population. Post bottleneck populations show less genetic variance than Post bottleneck populations . Post bottleneck populations show less genetic variation than pre bottleneck populations.
To be precise, the bottleneck population stage is when the population size of a given species dramatically decreases. It might be the result of human or natural activities. There are some species who struggle against all difficulties to survive, for whatever cause.
They therefore go through certain genetic changes to withstand the rate of decline. Low genetic diversity is only present in this population for the purpose of protecting them from the harmful effects brought on by environmental changes.
