The correct statement about the bears' gene pool after a bottleneck event that reduces the population by 80% is:

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

When a population undergoes a bottleneck event, the genetic diversity is significantly reduced because only a small number of individuals contribute to the gene pool of the next generation. This reduced genetic variability can lead to an increased prevalence of disadvantageous traits, particularly if those traits were already present in the remaining population.
