WebMeiosis I : Reductional Cell Division Sexual reproduction in organisms takes place through the fusion of male and female gametes, the sperm and the egg respectively. Gametes are haploid in nature, i.e., they contain only half the number of chromosomes. This genetic content makes them different from other body cells. WebOct 8, 2024 · Interphase. Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase is the first phase of interphase and is focused on cell growth. In the S phase, the DNA of the chromosomes is replicated.
