Question

Assertion (A): Species are groups of potentially interbreeding natural populations which are isolated from other such groups.

Reason (R): Distinctive morphological characters are displayed due to reproductive isolation.

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, but reason is not the correct explanation of assertion.

Explanation:

The assertion gives the biological species concept and is true. The reason is also true in general, but distinctive morphology is not the explanation for the definition based on interbreeding and reproductive isolation.
