WebJul 17, 2024 · Interphase. Ed Reschke/Getty Images. There are two stages or phases of meiosis: meiosis I and meiosis II. Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. At the end of the meiotic process, four daughter cells are produced. G1 phase: The period prior to the synthesis of DNA. WebIf crossing over occurs between a homologous pair of chromosomes during Meiosis, what will be present in the gametes?
