Question: State two proteins that determine human blood group.

Linda Kokwaro answered on 18 May 2022:

the main antigen (proteins) are A antigens and B antigens that are found on red blood corpuscles (RBCs). For example for blood group A, it means there are A antigens on the RBCs but anti-B antibodies in the plasma, blood group B has B antigens on the RBCs, with anti-A antibodies in the plasma, blood group O has no antigens but has anti-A and anti-B antibodies and blood group AB has both A and B antigens but no antibodies
