Within the ABO/Rhesus Group systems which are used to classify most blood types, there are several rare blood types. The rarest is AB-, with less than one percent of the world's population having this blood type. B-and O-are also very rare, each accounting for less than 5% of the world's population.
The genotype of blood type A is AA or AO. The antigens on the blood cell are A and antibodies in the blood plasma are B. For blood type B, the genotype is BB or BO with B as the antigens and B as antibodies. The blood type AB (also known as universal blood recipients and rarest blood type) has the genotype to be AB.
