There are three different alleles for human blood type, known as $IA, IB$, and $i$.  Description of the pair of alleles in our $DNA$ is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human $ABO$ genetic locus. The different possible genotypes are $AA, AO, BB, BO, AB,$ and $OO.$ 

The possible human phenotypes for blood group are type $A$, type $B$, type $AB,$ and type $O.$
