Web20 nov. 2024 · Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis. In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, but the second round is more like mitosis. In mitosis, prophase, metaphase, anaphase and telophase occur once. Prophase. WebNext comes metaphase. During this stage the sister chromatids align along the center of the cell so which equally chromatids face toward opposite poles of the cell. Radioactive Basics. Immediately the sister chromatids are ready to be divided. This occurs while anaphase through a shortening from the microtubules attached to the kinetochores.

WebProphase I is further divided into sub-stages: Leptotene: In this stage, the initiation of chromosome condensation takes place and it attains a composite form. Zygotene: In this, the homologous chromosomes pairs, the process is called chromosomal synapsis. It is followed by the generation of a composite composition called the synaptonemal ... WebMeiosis II happens in four stages: prophase II, metaphase II, anaphase II, and telophase II plus cytokinesis. During anaphase II, sister chromatids are separated. Meiosis II is a lot like mitosis, except that instead of two identical diploid daughter cells as in mitosis, meiosis II ends with four haploid, genetically different daughter cells.
