Both A and R are true and R is correct explanation of the assertion. Explanation: The father has a cleft chin, which is an inherited trait, and he passes this trait to his newborn son through his genes. Therefore, Assertion (A) is true. Inherited characteristics are determined by genes present in the DNA. These genes are carried by the reproductive cells (gametes) and are transmitted from parents to their offspring during reproduction. Therefore, Reason (R) is true and correctly explains the assertion. Hence, both A and R are true and R is the correct explanation of the assertion.
