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. Now, these are the same as the initial parental chromosomes and so they are non recombinant. Now, we have about a 40% chance of these occurring, and about a 40% chance of these occurring. So that means now the ratio of this to this to this to this is not one to one to one to one, but it's 40 1010 40, or we can say 40 40 1010.
