Question

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?a) Species B is more prone to extinction. b)Species B has less resistance to diseases as compared with Species A. c)Species A have no fear of extinction. d) Species A are more prone to extinction.

Answer 1

d) Species A are more prone to extinction.
this is because that when there is less genetic variatian mutations are more likely to occur. d is the only logical answer. When we have more genetic variatian it means that the body is in better shape than it would be if it was asexually produced.

Answer 2

Answer: Option d  Species A are more prone to extinction.

Explanation:

The difference between the DNA sequences amongst the individuals living in a population is defined as the genetic variation. The genetic variations allows the individuals to adapt to different environmental conditions and hence, increases the survival chances of a particular species.

Since, species A have fewer genetic variations, it is more prone to extinction in case of any sudden environmental change because decreased genetic variation leads to a lesser probability of survival of the individuals of a species.
