(A) In the $ABO$ blood grouping system,the inheritance is controlled by the gene $I$ which has three alleles: $I^A, I^B,$ and $i$.$1$. Phenotypes: The possible blood groups are $A, B, AB,$ and $O$. Thus,there are $4$ possible phenotypes.$2$. Genotypes: The possible combinations of these three alleles are $I^AI^A, I^Ai, I^BI^B, I^Bi, I^AI^B,$ and $ii$. Thus,there are $6$ possible genotypes.Therefore,the number of phenotypes is $4$ and the number of genotypes is $6$.

In the $ABO$ blood grouping system,what are the number of possible phenotypes and genotypes,respectively?
