Species A are more prone to extinction.

Answer 1

Species a are more prone to extinction

Answer 2

The correct answer is D. Species A are more prone to extinction.

Explanation

Genetic variation is a term that refers to the diversity that exists in a single species. This characteristic is important because it allows a species to adapt more easily to an ecosystem as one species with genetic variation it can overcome environmental difficulties and changes in the environment through evolution and natural selection than one with few genetic variations; also, it prevents the extinction of species. According to this,, species B has more possibilities of adapting to the changes or possible threats as a result of a greater amount of genetic variations, while species A, which has fewer genetic variations could extinguish first. So, the correct answer is D. Species A are more prone to extinction.
