Expert Solution
Step 1

Karl Landsteiner explained that the reactions between the erythrocytes (RBCs) and serum were related to antigens' presence on the RBCs and antibodies in the serum. Agglutination occurred when the antigens present on RBC were bound to the antibodies in the serum. According to the presence of antigen, blood groups are named A, B, O, and AB.
