Explain different types of blood groups and donor compatibility by making a table.

1. There are two types of blood grouping which are ABO and Rh.


2. ABO grouping is based on the presence or absence of two antigens on the RBC’s which are A and B.


3. These are three alleles IA,IB andI O.


4. Gene IA IA or IA IO Codes for blood group A


5. Gene IBIB or IBIO Codes for blood group B.


6. Gene IOIO Codes for blood group O.


7. Gene IAIB Codes for blood group AB.


8. People with blood group A, have antigen A on the surface of the RBC’s and produce antibodies against blood group B.


9. People with blood group B have antigen B on the surface of the RBC’s and produce antibodies against blood group A.


10.People with blood group AB have antigen A and B on the surface of the RBC’s and produce no antibodies.


11.People with blood group O have no antigens on the surface of RBC’s and produce antibodies against both A and B blood group.



13. This shows that blood group AB is a universal recipient and blood group O is a universal donor.
