For meiosis to occur it must go through two divisions, meiosis i and meiosis ii. This is where one cell gives rise to two genetically identical daughter cells. Meiosis 1 separates the pair of homologous chromosomes and reduces the diploid cell to haploid. Daughter cells produced at the end of two divisions are haploid n.
