AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
In sexual reproduction, DNA comes from two parents, combining their genetic material. This mixing produces new combinations of traits in offspring. In asexual reproduction, only one parent is involved and offspring arise mainly from DNA copying, introducing only minor errors. Thus, sexual reproduction generates far greater variation.

The key point examiners look for is two parents → mixing/combining of DNA → more variation. Contrast this with asexual reproduction where variation arises only from small copying errors. Mentioning both sides strengthens the answer for full 2 marks. Avoid vague statements like "more diversity"; be specific about why (combining genetic material from two individuals).
