Which cellular process of nuclear division produces four genetically non-identical haploid gametes from a single diploid germ cell?
Answer and explanation
Correct answer: A. Meiosis
- Step 1: Meiosis involves two sequential cell divisions (Meiosis I and Meiosis II) following a single round of DNA replication. Step 2. Crossing over during prophase I and independent assortment at metaphase I generate genetic variation in the four resulting haploid cells. Answer: Meiosis. Why not the others: Mitosis generates two genetically identical diploid somatic cells; amitosis is direct nuclear cleavage; binary fission is prokaryotic.
