The correct statement is: It has temporarily decreased, so disadvantageous traits are more likely to be passed on.

This is because a bottleneck event reduces genetic diversity by significantly decreasing the population size, which can lead to a limited gene pool. Consequently, the likelihood that disadvantageous traits are passed on can increase due to the reduced variety in mating options and the focus on the remaining individuals in the gene pool.
