…Diploid cells; Meiosis gives 4x number of Monoploid or Haploid cells
<Tab/>Mitosis has 1 cell division; Meiosis has 2
<Tab/>Anaphase of Mitosis has centromeres split (homologous chromosomes separate & chromosomes separate); Anaphase 1 of Meiosis has segregation of whole homologous chromosomes, Anaphase 2 has separation
<Tab/>Both have DNA synthesis in Interphase, but meiosis doesn't have DNA synthesis btwn its 2 divisions
