Which type of cell division is typically involved in asexual reproduction?

• A. Meiosis
• B. Binary fission
• C. Mitosis
• D. Conjugation

Answer: (C)

In asexual reproduction, the offspring are typically exact copies of the parent because the division that happens in the nucleus and then the cytoplasm preserves the parent’s genetic material. In eukaryotic organisms, this process is mitosis. It splits the chromosomes equally and creates two genetically identical daughter cells, keeping the chromosome number the same and enabling cloning of the parent’s genetic material. Meiosis, by contrast, reduces chromosome number and mixes genes, which is useful for sexual reproduction rather than cloning. Binary fission is the prokaryotic equivalent process in bacteria and some single-celled organisms, but it’s categorized differently from mitosis because these cells lack a nucleus and the internal machinery is not the same. Conjugation is genetic exchange between cells, not a division that creates new cells. So, for typical asexual reproduction in organisms with a nucleus, mitosis is the mechanism responsible for producing identical offspring.
