Answer 1

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, meaning that the gene pool becomes smaller. This reduction can lead to an increased likelihood of disadvantageous traits being passed on, as there are fewer individuals to contribute a diverse range of genes.
