    • Genetic variation arises in TWO stages during MEIOSIS or sexual reproduction
      • 1.  During meiosis 1, CROSSING OVER of genetic material occurs between pairs of paternal and maternal homologous chromosomes
    • As a result there is a RANDOM MIX of both maternal and paternal chromosomes, which leads to further genetic variation
