The correct statement about a bottleneck event is: "A bottleneck event decreases the gene pool of a population."
A bottleneck event occurs when a population undergoes a sudden and drastic reduction in size, leading to a decrease in genetic diversity. This reduction can be caused by natural disasters, human activities, or other factors. Because only a small subset of the original population survives the bottleneck event, genetic variation is lost, and the gene pool of the population becomes smaller. This can have negative consequences for the long-term survival and adaptation of the species.
Which statement is correct about a bottleneck event?
• A bottleneck event increases the gene pool of a population.
• A bottleneck event decreases the gene pool of a population.
• A bottleneck event decreases the population of a species permanently.
• A bottleneck event increases the population of a species permanently.
