If the father has $AB$ blood group and mother has $A$ blood group,then the children born to them will have the following blood groups $EXCEPT$ . . . . . . .

The genotypes of a husband and wife are $I^AI^B$ and $I^Ai$ respectively. How many different genotypes and phenotypes are possible among their children?

As per the $ABO$ blood grouping system,the blood group of the father is $B^{+}$,the mother is $A^{+}$,and the child is $O^{+}$. Their respective genotypes can be:
Choose the most appropriate answer from the options given below:
$A. I^Bi / I^Ai / ii$
$B. I^BI^B / I^AI^A / ii$
$C. I^AI^B / iI^A / I^Bi$
$D. I^Ai / I^Bi / I^Ai$
$E. iI^B / iI^A / I^AI^B$

If the mother's blood group is $B$ and the father's is $A$,what blood group$(s)$ can their offspring have?

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

If both parents have blood group $AB$, which blood group cannot be found in their child?
