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%. So we see that forming a female and a male are equally likely events. So this is 50% chance and this is 50% chance. Now, earlier when I mentioned when I introduced the X chromosome, I said that the X chromosome contains many genes that are involved in expressing proteins that basically are important in not only the female individual, but also the male individual.
