Vedclass · Answer

(C) The $ABO$ blood grouping in humans is controlled by the gene $I$. This gene has three alleles: $I^A, I^B,$ and $i$. - The alleles $I^A$ and $I^B$ produce slightly different forms of the sugar polymer on the surface of red blood cells,while the allele $i$ does not produce any sugar. - Because there are three different alleles involved in determining the phenotype,this is an example of multiple allelism. - Therefore,the correct number of alleles is $3$.
