Is an individual that has three X chromosomes. So this will be replaced with an X chromosome. We combine and so we'll form a Zygote that has anapply that will contain axxx genotype arrangement. So an X and X and an X. Likewise, if we take this sperm cell and combine it with the normal XL, we're going to have an arrangement of XYY. And finally, if either one of these two sperm cells for or combines with a normal xcel, we're going to have an EXO condition, just like we had in this particular case.
