(C) In the $ABO$ blood grouping system,the inheritance is controlled by the gene $I$. The gene $I$ has three alleles: $I^A$,$I^B$,and $i$.Because there are three alleles,the possible genotypes are $I^A I^A$,$I^A i$,$I^B I^B$,$I^B i$,$I^A I^B$,and $ii$ (total $6$ genotypes).However,the phenotypes are determined by the expression of these alleles. The alleles $I^A$ and $I^B$ are dominant over $i$,and $I^A$ and $I^B$ are codominant with each other.- Genotypes $I^A I^A$ and $I^A i$ result in blood type $A$.- Genotypes $I^B I^B$ and $I^B i$ result in blood type $B$.- Genotype $I^A I^B$ results in blood type $AB$.- Genotype $ii$ results in blood type $O$.Thus,there are $4$ possible phenotypes: $A$,$B$,$AB$,and $O$.
