And so each one of these possibilities is 25%. Now, in this particular case, because of the two types of individuals we combine all these offspring will look exactly the same. They have the same exact phenotype, and they will have the same exact genotype. And in the next several lectures, we're going to examine many more examples where we're combining different types of organisms, different from what we actually did here. So we see that what a Punnett square actually is. It's the really useful tool that is used by scientists in genetics to basically determine the potential possibilities of the genotype of that offspring.
