Question:
Assertion (A): In protozoans, offspring formed by asexual reproduction are genetically similar.
Reason (R): Uniparental inheritance.
Assertion (A): In protozoans, offspring formed by asexual reproduction are genetically similar.
Reason (R): Uniparental inheritance.
Show Hint
Asexual reproduction + uniparental inheritance generally produces genetically identical offspring (clones).

- Both (A) and (R) are true, (R) is the correct explanation for (A)
- Both (A) and (R) are true, (R) is not the correct explanation for (A)
- (A) is true, but (R) is false
- (A) is false, but (R) is true

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Asexual reproduction involves only one parent.
Step 1: Analyze Assertion. Protozoans commonly reproduce by binary fission. Offspring are genetically identical to parent. Thus Assertion is true.
Step 2: Analyze Reason. Only one parent contributes genetic material. This is called: \[ \text{Uniparental inheritance} \] Hence Reason is true.
Step 3: Establish relationship. Because genetic material comes from a single parent, offspring remain genetically similar. Therefore Reason correctly explains Assertion. \[ \boxed{\text{Both A and R are true and R explains A}} \] Hence option (A) is correct.
