WebJan 9, 2024 · Stages of Meiosis. Each of the two meiosis has four steps: Prophase, Metaphase, Anaphase, and Telophase. Before the start of meiosis, the cells undergo a growth period called interphase which includes the G1, S, and G2 phases. G1 (gap) phase − The phase where an increase in cell mass takes place to prepare for cell division. WebApr 4, 2024 · Meiosis is split into meiosis I and meiosis II which are further divided into Karyokinesis I and Cytokinesis I and Karyokinesis II and Cytokinesis II respectively.

In … WebThe reduction in chromosome number is achieved by the process of meiosis. In meiosis, there are usually two steps, Meiosis I and II. In Meiosis I homologous chromosomes segregate, while in Meiosis II sister chromatids segregate. Most multicellular organisms use meiosis to produce gametes, the cells that fuse to make offspring.
