WebThere are two types of cell division. Mitosis produces two identical diploid daughter cells. Meiosis produces four non-identical haploid gametes (sex cells). WebDec 18, 2016 · The stages of meiosis are divided into two parts, meiosis I and meiosis II This is how meiosis creates haploid cells that can be used for sexual reproduction. When two of these cells combine, it will lead back to the original diploid cell with 2n and 2c. So, we’ve covered the general process of meiosis and how it is different than mitosis.
