So we form sperm cell number two and the same thing happens here. This entire pair of identical cytochromatids moves into sperm cell number one. And the other one basically gets nothing. 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?
