Mitosis yields two genetically identical diploid daughter cells.

Mitosis yields two genetically identical diploid daughter cells.

• A. True
• B. False
• C. It yields two haploid daughter cells
• D. It yields two diploid but genetically different cells

Answer: (A)

Mitosis preserves chromosome number and genetic content, producing two genetically identical diploid daughter cells. In somatic cells, DNA is replicated before division, creating sister chromatids that are exact copies. When mitosis proceeds, these sister chromatids are pulled apart and evenly distributed into the two new nuclei. Cytokinesis then separates the cytoplasm, resulting in two daughter cells that each have the same diploid chromosome complement as the original cell and the same genetic information. Because there’s no recombination or reduction of chromosome number in this process, the daughter cells are genetically identical to each other (aside from rare mutations that may occur). This is why the statement is true. The alternative about producing haploid cells would describe meiosis, and the idea of two diploid but genetically different cells contradicts the fact that mitosis aims to maintain identical genetic content.
