This one is uppercase B, uppercase B or lowercase B, lower case B. And the same thing with these two. Okay, so these are kind of the possibilities of our genotype. So let's actually pick one and see that they are consistent. So let's begin with these two phenotypes here. So when we cross BB with BB, the only type of phenotype that we form is obviously lowercase B, lowercase B, and that is absolutely consistent with these two individuals here.
