1. The problem asks: Which of these processes produces gametes in meiosis? 2. Let's define the terms: - Fertilization: The fusion of two gametes to form a zygote. - Binary fission: A form of asexual reproduction in prokaryotes. - Mitosis: Cell division producing two identical daughter cells. - Meiosis: Cell division producing gametes (sex cells) with half the chromosome number. 3. Important rule: Gametes are produced only by meiosis, which reduces the chromosome number by half to maintain genetic stability across generations. 4. Therefore, the process that produces gametes is **Meiosis**. Final answer: Meiosis
