Question

A bottom like event reduces the population of bears in one area by 80%. Which statement is correct about the bears gene pool?

1. Is temporarily decreased, so disadvatageous traits are less likely to be passed on
2. It has temporarily decreased so disadvantages traits are more likely to be passed on
3. It is temporarily increased, so disadvantage traits are more likely to be passed on
4. It is temporarily increased so disadvantaged traits are less likely to be passed on

1. Is temporarily decreased, so disadvantageous traits are less likely to be passed on

The reduction in population due to the bottleneck event means that there are fewer individuals contributing genetic diversity to the gene pool. This can result in a decrease in the frequency of disadvantageous traits as they are less likely to be passed on.
