And so we have four gametes here, four gametes here from the two different parents, and when they mate, when they fuse to form the Zygote, these are the 16 possibilities for the genotype of our Zygote. Now, the next question is what are the four types of phenotypes of these individuals produced here? So, we can either have green and tall we can either have green and short, we can have yellow and tall, or we can have yellow and short. So let's actually tally up and determine the probabilities or the distribution probability of the F two offspring. So all these squares describe the offspring, the F two generation offspring. So basically, let's begin with this one.
