So let's suppose we take either one of these two sperm cells, our anuplooid sperm cell and we combine it with a female normal X cell. Remember, X cells always or normal X cells always have one X chromosome. Now, if these two gametes actually combine, we're going to form a Zygote that has the unequality condition. And what that means is we're going to have two of these X chromosomes, one of these Y chromosomes. And what happens is we know under normal conditions we should have one X, one Y or one X, one X. But because of this rearrangement, we're going to have an extra copy of that X chromosome.
