Question

After surviving a bottleneck, a population recovers to the point where it consists of as many individuals as it did prior to the bottleneck. Which of the following statements is most likely to apply to this population?
a.The postbottleneck population exhibits less genetic variation than the prebottleneck population.
b.The bottleneck subjected the population to stabilizing selection.
c.The postbottleneck population has less of a chance of going extinct than did the prebottleneck population.
d.The postbottleneck population exhibits more genetic variation than the prebottleneck population.
e.The postbottleneck population has the same probability of going extinct as did the prebottleneck population.

Answer 1

The post bottleneck population exhibits less genetic variation than the pre bottleneck population.

Answer: Option A

Explanation:

To be precise the bottle neck population is a stage where a particular species undergo dramatic reduction in their population size. It may be due to natural or human activity. Whatever reason might be there are some species that fight to thrive to exist among all odds.  

Hence they undergo certain genetic variation to withstand the declining rate. Low genetic variation is only exhibited in this population so that they do not become a prey for the deleterious effect caused in the environmental changes.

Answer 2

Answer:

c
