Remember, the punant square is the tool that we use in genetics that allows us to determine all the different potential possibilities for the genotype of that particular offspring. So we begin with a parent that has uppercase T, uppercase T, and the other parent has lowercase, lowercase T. And they mix, they make their cross and they produce a certain offspring. So let's begin with the homozygous dominant, which means we have uppercase uppercase T. And when we produce the gametes, the two T separate into individual cells. So let's suppose we have uppercase T and we have uppercase T. Now the other pan has lowercase T, lowercase T. So these two individual genes separate during the process of meiosis to basically form the gametes. And so we have gamete one and we have gamete number two. So what happens when this mixes with this?
