How can variation sometimes arise even in asexual reproduction?
Answer and explanation
Correct answer: Through small errors during DNA copying
Asexual reproduction usually produces genetically similar offspring because only one parent contributes genetic material. However, DNA copying is not perfectly error-free. Small copying errors, or mutations, may arise and can create a new inherited variation if they occur in reproductive cells or the organism’s reproductive lineage. Therefore C is correct. Food does not always alter genes, colour does not change automatically, and two-parent contribution describes sexual reproduction.
