Only two pairs of chromosomes are shown in the diagrams … WebHowever, interphase does not describe a cell that is merely resting; rather, the cell is living and preparing for later cell division, so the name was changed. A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage.
WebJan 22, 2024 · The first round of cell division is complete. The two non-identical, haploid daughter cells now enter the second stage of meiosis. Meiosis II Meiosis II is very similar to the process of mitosis, except it involves two haploid cells rather than one diploid cell. Phases of meiosis II Prophase II During prophase II, the chromosomes condense. WebCell division by mitosis can be divided into the following 5 stages: Interphase, Prophase, Metaphase, Anaphase, and Telophase.
