3 Blood Type four types: A B AB O
the Rh factor refers to whether the blood has the immunogenic D antigen this is independent of the ABO system

4

5 Blood Type the antibodies recognize foreign antigens and work to destroy them A and B are co-dominant and O is recessive to both Canadian Blood Services Blood Types Tutorial

6 Blood Type genotypes: Allele IA produces antigen A
Allele IB produces antigen B Allele i produces no antigen the I stands for isohemagglutinin (compound that allows for clumping)
