    , diploid cells undergo 2 cell divisions that result in 4 haploid cells. Meiosis occurs in sex cells, produces gametes, increases genetic diversity and produces genetically unique cells. It takes place only at certain times in an organism’s life cycle and is involved in sexual reproduction. (1/24...
