There are two different species in a habitat.  species a has fewer genetic variations.  species b has a considerable amount of genetic variations. which of these statements is true? species b is more prone to extinction. species b has less resistance to diseases as compared with species a. species a have no fear of extinction. species a are more prone to extinction.

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.
