Four major blood phenotypes (A, B, AB, and O) are determined by three alleles: A, B, and O. A person with type A has a certain protein on their blood cells' membranes. A person with type B has a different protein on their cells' membranes. Cells from type AB have both proteins, but cells from type 0, which is recessive, has neither protein
