Vedclass · Answer

(A) The blood group $O$ is determined by the genotype $ii$. For a child to have blood group $O$ $(ii)$,both parents must contribute an $i$ allele. Parents with blood group $AB$ have the genotype $I^A I^B$. Since they do not possess the $i$ allele,they cannot produce a child with blood group $O$ $(ii)$. Therefore,parents with blood group $AB$ cannot have a child with blood group $O$.

If a child has blood group $O$,which of the following blood groups cannot be possessed by the parents?
