Web7 apr. 2024 · To understand what meiosis is, let us take a look at its different stages. There are 6 stages of meiosis into every cell division – Prophase, Prometaphase, Metaphase, Anaphase, Telophase and Cytokinesis. Meiosis I . Meiosis I is the initial round of nuclear division, which is also called reduction division. WebMeiosis is the process of cell division used for sexual reproduction in eukaryotes. The chromosomes in the cell are cut in half and then combine with a haploid from the other parent. The cells produced by meiosis are usually diploid again.
