So if we carry out the punitive square, we get the following distribution of phenotypes. So in this or the following genotypes, in this particular genotype, we produce the AB group. So the AB phenotype in this particular case, one is lowercase I, the other one is lowercase B, or a lowercase a upper case I A. And what that means is we're going to produce the protein A. And so the phenotype will be group A in this particular case. And in this particular case, we're going to have group B.
