Individual microtubules connect to the kinetochore of each chromosome at the centromere. These rearrange the paired homologous chromosomes (bivalents) so that they line-up along the cell equator. 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.
