And then we have uppercase T, lowercase T, there you go. Now we have uppercase g, lowercase g, so we have uppercase g, lowercase G that comes from this gamete, and we have two lowercase recessive T's for the short trait here. We have lowercase g, lower case g, we have uppercase T and lowercase T, and finally we have the possibility of everything being recessive. So we have lowercase g, lower case g, and we have lowercase T, lowercase T. So these are the 16 different possibilities of the genotype for the offspring when these two mate with themselves. So we have one of these mates with itself. So each one of these produces four types of gametes.
