Detailed explanation-1: -The individuals who have a specific B+ type blood group have the B-antigen on the surface of RBC. But the antibodies which are present in the blood include the anti-A antibody so that they do not react with the cell surface antigen of the same person.
Detailed explanation-2: -The ABO classification is the most important and relevant for blood compatibility. A small number of antigens and antibodies are responsible for the ABO blood types. A antigen (attached to red blood cell) B antigen (attached to red blood cell) Anti-A antibody.
Detailed explanation-3: -You can have either A, B or A+B antigens and in addition to that you can be either rhesus positive (antigen present) or negative (no rhesus antigen). The example is type A negative blood meaning that red blood cells have the A-antigen but not the rhesus antigen.
