And we have the separation of these chromosomes to that side and these chromosomes to the other side. And so in this particular case, we formed these two identical sperm cells. And in this particular case, we formed these two sperm cells that don't have those sex chromosomes. So all of these sperm cells are abnormal because in this case, in case one and two, we have one more than we should remember. Each sperm cell should have only one sex chromosome. In this case, we have two.
