(A) The $ABO$ blood group system in humans is an example of multiple alleles.There are three alleles: $I^A$,$I^B$,and $i$.- $I^A$ and $I^B$ are codominant,while $i$ is recessive to both.The possible genotypes are: $I^A I^A$,$I^A i$,$I^B I^B$,$I^B i$,$I^A I^B$,and $ii$.The corresponding phenotypes are:$1$. $I^A I^A$ and $I^A i$ result in blood group $A$.$2$. $I^B I^B$ and $I^B i$ result in blood group $B$.$3$. $I^A I^B$ results in blood group $AB$.$4$. $ii$ results in blood group $O$.Thus,there are a total of $4$ phenotypes $(A, B, AB, O)$.

In humans,the $ABO$ blood group is controlled by the $I$ gene. It has three alleles: $I^A$,$I^B$,and $i$. Although there are three different alleles,six different genotypes are possible. How many phenotypes are observed in this case?
