So these two will separate independently of these two. And likewise, these two will separate or segregate independently of these two. And what that means is, within the cell, these two can be arranged like so, or they can actually be switched, because that's what we mean by these being independent to the movement of these. So it turns out about 50% of the cells have this arrangement, but the other 50% of the cells actually could also have this arrangement. So these upper case TS can be on this side, and these lowercase TS can be on this side, or we can have this. And these two, as we'll see in just a moment, will actually produce different types of gametes.
