Hint

Think about whether there is any mixing of DNA from two different sources in asexual reproduction.

Quick Oral Answer

Asexual reproduction involves only one parent, so there is no fusion of gametes. The offspring receive an exact copy of the parent's DNA, making them genetically similar.

Analysis & Explanation

Assertion (A) is true: Offspring produced by asexual reproduction are genetically highly similar (often identical clones) to their parents. This is because the DNA copying process occurs within a single cell/individual without any mixing of genetic material from another individual.
Reason (R) is true: Asexual reproduction, by definition, involves only a single parent.
Explanation: Because there is only a single parent involved, there is no fusion of gametes (which would combine different genetic lines) and no meiosis to halve the genetic material. The offspring inherit their entire genetic blueprint directly from the single parent's DNA copies. Therefore, the fact that asexual reproduction involves a single parent directly explains why the offspring are genetically similar to the parent. Thus, (R) is the correct explanation of (A).

Common Mistakes

1Students sometimes think that because minor variations occur during DNA copying, the offspring cannot be called 'genetically similar'. However, they are highly similar compared to sexually reproduced offspring.

Interesting Facts

Plants propagated vegetatively, like sugarcane or potatoes, are genetic clones of their parent, which is why farmers can maintain consistent crop quality across generations.
