How can a little variation occur even in asexual reproduction?
Answer and explanation
Correct answer: By small errors during copying of genetic material
Asexual reproduction usually involves one parent, so the offspring are genetically very similar to that parent. However, DNA copying is not perfectly error-free. A small copying error can create a mutation, and if it is retained in the offspring, it produces slight variation. Therefore option A is correct. Fusion of two parents describes sexual reproduction, while food changes do not directly rewrite inherited DNA.
