A child of a mother with blood group $A$ and a father with blood group $AB$ may have any one of the following blood groups except
A
$A$
B
$B$
C
$AB$
D
$O$
Solution
(d) Since the blood group of father is $AB$ (genotype $AB$),
therefore one of the two antigens i.e. $A$ or $B$ has to be present in child's blood i.e. he can have any other blood group but not $‘O’$ (genotype $OO$).
