7.3: Mitotic Phase - Mitosis and Cytokinesis

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. WebThe dividing mother cell must provide both daughter cells with a complete set of chromosomes. To do this, the stem cell must duplicate its chromosomes before cell division. This duplication is carried out during the synthesis phase of the cell cycle. The chromosomal duplication is then part of a duplicated chromosome.
