In the land of Oompah, blood type is quite unique. Oompahs can have type A, B, AB and O blood types which relate to the type of protein (immunoglobulin) present on the red blood cells. When both type A and B proteins are present they show up in equal distribution showing codominance. Their blood type also exhibits multiple alleles if a red blood cell is lacking type A and B proteins then it is type O (three possible alleles).
