Question

Assertion (A): Out crossing practice involves mating of animals with no common ancestor on either side for 4-5 generations.

Reason (R): A single outcross often helps to overcome inbreeding depression.

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:

Out-crossing involves mating animals of the same breed with no common ancestor for 4–5 generations. A single outcross can help overcome inbreeding depression, but that benefit does not explain the definition in the assertion.
