$AB$

Vedclass · Answer

(A) The child has blood group $O$,which means the genotype is $ii$. One $i$ allele is inherited from the mother and the other $i$ allele is inherited from the father. The mother has blood group $A$,so her genotype must be $I^A i$ to provide an $i$ allele to the child. The father must provide the other $i$ allele. Therefore,the father's genotype must contain at least one $i$ allele ($I^A i$,$I^B i$,or $ii$). $A$ person with blood group $AB$ has the genotype $I^A I^B$. Since an $AB$ individual does not possess the $i$ allele,they cannot be the father of a child with blood group $O$.

If a child has blood group $O$ and the mother has blood group $A$,which blood group cannot be the father's?
