The correct statement is:

It has temporarily decreased, so disadvantageous traits are more likely to be passed on.

A bottleneck event reduces the genetic diversity of a population because a significant portion of the population is lost. This reduction leads to a smaller gene pool, which can increase the likelihood that disadvantageous traits will be passed on, especially if the surviving population is not representative of the original population's genetic diversity.
