And so eventually, this Zygote will develop into a male individual. So we see that because there is a 50% chance of forming a sperm cell that is carrying the X chromosome, so we have 0.5 chance of that taking place, and we have 100% chance of the Xcel forming the X chromosome. So that is equivalent to 1.0. We multiply these two and we see that there is a 0.5 or a 50% chance of forming the female individual. And likewise, we can use the same exact mathematics in this particular case. So 50% chance of the sperm cell carrying the Y chromosome, zero five multiplied by 1.0, and that gives a 0.5 chance or 50%.
