So just like in this case, we have sperm cell two and sperm cell four that have nothing but sperm cell one, in this case contains two identical X chromosomes. In here, we have two identical Y chromosomes. And so now, if we study the same exact picture as we discussed in this particular diagram, if we take, let's say, sperm cell number one and we combine it with a normal X cell, what we're going to get? 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.
