Correct answer: "A bottleneck event decreases the gene pool of a population."

Explanation: A bottleneck sharply reduces population size, causing loss of alleles and reduced genetic diversity. It does not necessarily permanently change total population size (could recover in number) and it certainly does not increase genetic variation.
