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
This example illustrates which of the following phenomena? SC.912.L.16.1
