 We're back, and we're back again with the exact same human life cycle drawing. Don't get irritated with me for providing the exact same image for multiple parts of our course. Today, we are zooming in and focusing on yet another part of the human life cycle. In the last lecture, we talked about mitosis, which is the process of nuclear division that leads to identical daughter cells. And it's how we grow. In this lecture, and I warned you, make sure you understand mitosis before we move forward. So this is your moment of checking yourself. Do you understand mitosis? Because I'm going to count on you understanding it. So if you need to go back and review, go. Go shoo shoo review now. But if you stick with me here, then we're going to assume a relatively comfortable understanding of mitosis. And today, we get to talk about mitosis. This is a part of the life cycle that we haven't looked at yet. We've speculated on the fact that there's got to be a process to create gametes that have half the DNA. And in fact, we looked, look over here, we've got the word haploid. We already talked about haploid and diploid cells. And we looked at the fact that mitosis results in haploid cells that combine. Remember haploid cells have just one copy of every chromosome and two haploid cells combine. That would be an egg and a sperm. And that forms the diploid cell. You all as I go. That goes through mitosis to make the fantastic specimen you are. Myosis has several purposes. Number one, we have to get rid of half the chromosomes. Okay, that's super important. The reduction of a diploid cell into a haploid cell, that's a critical component of or a critical purpose of myosis. But number two, myosis is about generating genetic diversity in a population. Myosis is about sexual reproduction. And I'm going to argue that we're going to spend the rest of the course talking about sex. In fact, we have an entire lecture dedicated just to sexual reproduction and parasites. But you didn't know that those two were connected. But myosis provides the foundation for generating genetic diversity that we can then leverage in sexual reproduction. Alright, so let's look at an overview of myosis. Compare it to mitosis and then dig into some of the specific details.
