Bottleneck events lead to a. population growth b. an increase in inbreeding c. an enrichment of dominant genetic traits d. a reduced rate of species mutation

Answer;

B. an increase in inbreeding

Explanation;

The Bottleneck Effect occurs when there is a disaster of some sort that reduces a population to a small handful, which rarely represents the actual genetic makeup of the initial population. This leaves smaller variation among the surviving individuals.

A population bottleneck is an event that drastically reduces the size of a population. The bottleneck may be caused by various events, such as an environmental disaster, the hunting of a species to the point of extinction, or habitat destruction that results in the deaths of organisms.

the genetic bottleneck can lead to inbreeding depression; the reduction of the population's fitness due to an increased likelihood of breeding between relatives that share deleterious genetic variants.
