Question

Why are populations with high levels of genetic diversity more stable than populations with low levels of genetic diversity?

Answer 1

Answer:

D. Population with high levels of  genetic diversity are more likely to have individuals that will undergo natural selection if conditions change.

Explanation: Natural selection is the guiding force of evolution. It is  applicable to the gene pools of the  individuals. It favours those features of the  organisms of a population, that bring them more efficient adaptive relationship with their environment. This results descent with modifications. Natural selection is differential contribution of the alleles of a gene to the gene pool of a population in next generation. It leads to survival of fit animals from generation to generation. So the individual having high genetic diversity make the individual to adapt with the changing environment.

Answer 2

A. Populations with high levels of genetic diversity are more likely to have individuals with traits that help them survive if conditions change.
