Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Genetic recombination is an important mechanism of increasing genetic diversity in sexually reproducing organisms.
Reason (R) : Genetic recombination occurs during meiosis when homologous chromosomes exchange genetic material through crossing over, resulting in new combinations of alleles in the gametes.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

To test if the Reason explains the Assertion, read them together using the connector "because":
"Genetic recombination increases genetic diversity in sexually reproducing organisms BECAUSE crossing over during meiosis exchanges genetic material between homologous chromosomes, producing new combinations of alleles."
This reads as a logical, scientifically correct explanation.

Answer 1

The Correct Option is A
