So we have our purple t. Now, because we're crossing the same identical types of f one generation offspring, these four gamuts will be exactly the same. So we have a green here, a green here, then we have a blue here and we have a blue here, we have a purple here, a purple here, and we have an orange here and an orange here. So these are the four possibilities for the gametes from parent number two. And these are the four possibilities for the gametes for parent number one. And so essentially we're going to get 16 different possibilities for the offspring. So let's actually carry out the pond and square crossing.
