How can some variation arise even in asexual reproduction?
Answer and explanation
Correct answer: Through small errors in copying genetic material
Asexual reproduction usually involves one parent and produces genetically similar copies, but copying genetic material is not perfectly error-free. Small replication errors or mutations can alter DNA and create slight differences in the offspring. Therefore option A is correct. The union of two parents describes sexual reproduction, whereas complete absence of chromosomes would prevent normal development, and producing no offspring cannot create variation in a population.
