Which process produces two genetically identical diploid daughter cells?

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

Answer: (B)

Mitosis ensures equal chromosome distribution and preserves the chromosome number, yielding two genetically identical diploid daughter cells. After DNA is replicated, each chromosome consists of two sister chromatids. During mitosis, these chromatids separate and are pulled to opposite poles, and cytokinesis divides the cytoplasm to form two new cells. Each daughter receives a full diploid set of chromosomes with the same genetic content as the parent, aside from rare new mutations. Meiosis, by contrast, reduces the chromosome number and introduces genetic variation through crossing over and independent assortment, so the resulting cells are not two identical diploid daughters. Binary fission occurs in prokaryotes and yields two genetically identical cells but not diploid eukaryotic daughter cells. Budding produces a new, genetically identical cell but is not described as generating two diploid daughters in the same division event.
