Question

In 3-4 sentences What is a bottleneck event? Is it bad or good for population diversity?

Answer 1

A bottleneck event is a sharp reduction in the size of a population due to a sudden environmental or habitat change, natural disaster, or human activities. This can result in a decrease in genetic diversity within the population as only a small number of individuals survive and reproduce. Overall, bottleneck events are generally bad for population diversity as they reduce genetic variability and can increase the risk of inbreeding and genetic drift.
