Concept explainers
Introduction: Cell division is the process where the cells divide to produce two or more daughter cells. Mitosis and Meiosis are the two types of cell division. Mitosis involves the division of a single cell into two identical daughter cells. Meiosis involves the production of the sex cells, namely sperms and eggs. This process involves the division of a single cell twice to produce four daughter cells, which exactly contains half of the original chromosomes. Meiosis I and Meiosis II are the two phases of meiosis. In meiosis I, there will be a separation of the homologous pairs through the first round of the cell division. In meiosis II, there will be separation of the sister chromatids during the second round of the cell division.
