Okay? And so in the process of meiosis, when these segregate and at the end we form our haploid sperm cells, one sperm cell type will contain the X chromosome with the lowercase C, the red C. So let's suppose this is our X chromosome and the other sperm cell will simply contain the Y. So now let's actually carry out the Punnett square. Let's complete the Punnett square. So when this sperm cell combines with this X cell to produce the Zygote, the Zygote will have two X's. And what that means is we're going to have a female.
