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: 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.
