And so together we'll have 16 possibilities for the offspring. And to see why that is, so let's take a look at the following dihybrid cross, Punnett square so let's begin. Let's suppose that this column represents the column that describes the four possibilities for the gamuts of parent number one. So in this square, what do we place? Well, let's begin with this one right here. So we have a green g and a green t. So we have a green g and we have a blue or uppercase t. So this is gamete number one.
