The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis.
