उत्तर

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

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.
