In these two cases, both of the alleles are found on each of one of the two chromosomes, or not both of them. But I should say one is found on one chromosome and the other one is found on the other chromosome. And so in such a case, this is what we have. And this type of blood group is known as blood group AB. So an individual that has blood group AB, what that means is they have both of these alleles that code for these two proteins. Now, what about this particular case?
