Question
Endangered species are those that have rapidly declining populations. These species face extinction unless conditions change. In some cases conservation efforts are successful, and an endangered species begins to recover its population size.How does the bottleneck effect impact these species?A.It leads to increased rates of mutation in the recovering population.B.It causes speciation to occur in the recovering population.C.It results in reduced genetic diversity in the recovering population.D.It prevents natural selection from acting on the recovering population.
Solution
The bottleneck effect impacts these species by resulting in reduced genetic diversity in the recovering population. So, the correct answer is C. It results in reduced genetic diversity in the recovering population.
Here's why: The bottleneck effect is a sharp reduction in the size of a population due to environmental events or human activities. When a population size is dramatically reduced, the genetic variation of the population also decreases. This is because only a small, random sample of individuals (and therefore, genes) from the original population survives. This reduced genetic diversity can make the population more susceptible to diseases or changes in the environment, and it can limit the population's ability to adapt to new situations.
