Web—To understand how mitosis and meiosis are related, the first thing you need to know is that mitosis isn’t the only type of cell division that can occur. Meiosis is also a form of cell division and reproduction! But while mitosis results in two identical daughter cells, meiosis results in four sex cells. Web6. During interphase preceding meiosis, each chromosome replicates itself and becomes two chromatids joined at the centromere. These identical chromatids are known as sister chromatids.
