Question

Which statement is correct abut a bottleneck event?

A ) A bottleneck event increases da population of species permanently

B ) A bottleneck event decreases da gene pool of a population

C ) A bottleneck event decreases da population of a species permanently

D ) A bottleneck event increases da gene pool of a population

Answer 1

The correct statement about a bottleneck event is:

**B) A bottleneck event decreases the gene pool of a population.**

A bottleneck event typically occurs when a population's size is significantly reduced for at least one generation, which can lead to a decrease in genetic diversity. This reduction in the gene pool can have long-term effects on the population's ability to adapt to environmental changes.
