Which statement is correct about a bottleneck event? (1 point)

Question

• A bottleneck event decreases the population of a species permanently.
• A bottleneck event decreases the gene pool of a population.
• A bottleneck event increases the gene pool of a population.
• A bottleneck event increases the population of a species permanently.

Answer 1

The correct statement about a bottleneck event is: "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 loss of genetic diversity and a smaller gene pool.
