The correct statement is:

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

A bottleneck event significantly reduces genetic diversity within a population because only a small number of individuals contribute to the gene pool. This decrease in genetic diversity can lead to a higher likelihood of inbreeding and the expression of disadvantageous traits, as the gene pool becomes less varied.
