In this particular case, we have uppercase G and we have a lowercase T. In this case, we have an uppercase. Well, let's actually finish off we have this one here, this one doesn't change. So we have a T, lowercase T, and an uppercase G. This one here is this one here. So we have a lowercase G and an uppercase T. So that one changes with respect to this initial starting point. Okay, so we see that just like in part A, we have these four possibilities taking place, but in part A, we saw that the ratio was one to one to one to one in part b, because crossing over takes place at random, about 10% of our gametes produced from this individual. So about 10% will be lowercase G, uppercase T, about 10% will be uppercase G, lowercase T. And so these two types of gametes are known as the recombinant gametes because they are a result of the process of crossing over.
