WebbProphase, metaphase, anaphase, and telophase both occur in meiosis one and meiosis two. Meiosis One Before a gamete cell can go through meiosis one, it must proceed through Interphase. During Interphase, the sex cell grows in preparation for cellular division. As it grows, it makes copies of its chromosomes.
