Current Question (ID: 14433)

Question:

Different blood groups are due to:

Options:

1. Specific antigens on the surface of WBCs
2. Specific antibodies on the surface of RBCs
3. Specific antigens on the surface of RBCs
4. Specific type of haemoglobin in RBCs

Solution:

Different blood groups are due to the presence or absence of specific antigens (molecules that can trigger an immune response) on the surface of red blood cells (RBCs). The most common blood group system is the ABO blood group system, which is determined by the presence or absence of two antigens, A and B, on the surface of RBCs. Another important blood group system is the Rh blood group system, which is determined by the presence or absence of a specific Rh antigen on the surface of RBCs.
