I'm not going to do your homework for you but I will explain how to do it. For each of the parents, figure out all possible combinations (for the first one it would be PT and pT for the second it is pT and pt). Make a punnet square, it will have to be 2x2 seeing as you have two possible combinations for both of the parents. Fill in the punnet square.
