Question

Assertion (A): Species with low genetic variability are generally at greater risk of extinction than the species with more genetic variability.

Reason (R): Species with low genetic variability are more vulnerable to diseases, predators or other environmental challenges.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

Explanation:

Low genetic variation limits a population’s ability to adapt to changing conditions. This makes it more vulnerable to disease, predators and environmental challenges.
