Meiosis
Each chromosome finds its Harmologus counter part, these matching pairs hold the same amount of genetic info from both your mom and your dad. Then the pair trades genes which is called crossing over. The spindle then places your maternal and paternal chromosomes randomly, on each side of mid line. Finally the spindle fibers pull apart leaving the sister chromatids in tact, thus making twice enough info the cell needs. Then it creates four unique sets of chromosomes, we call these haploid cells since they hold half the info. These cells will most likely become sperm or egg cells.
