What is the biological significance of genetic diversity between populations?

The question is incomplete as it does not have the options which are:

A) Genes for adaptive traits to local conditions make microevolution possible.

B) The population that is most fit would survive by competitive exclusion.

C) Genetic diversity allows for species stability by preventing speciation.

D) Isolated populations become more fit.

E) Diseases and parasites are not spread between separated populations.

Answer:

Option-A

Explanation:

Genetic diversity refers to the diversity which arises in a population due to the genetic recombination. The genetic recombination allows the organism to mutate and the organism can evolve within a short period.

In the given question, if the population has large genetic diversity then it represents the evolution in short duration of time and the species have been formed through microevolution.

Thus, Option-A is correct.
