ABO blood group:

 
  • ABO blood groups in human beings were reported for the first time by Karl Landsteiner. According to this system, humans can have 4 types of blood groups, A, B, AB and O
  • A,  B and O blood groups were discovered by Landsteiner while AB blood group was discovered by de Castello and Steini.
  • ABO blood groups are determined by the gene Ig which has three alleles Ia, Ib, and Io of this gene 
  • Allele Ia and Ib produce antigen A and antigen B respectively. 
  • RBCs of each blood group contain some antigens and they possess antibodies against other antigens in their plasma. 
     

                  

 

 

Antibodies are absent from serum in AB blood group. Hence, the correct answer is option a.
