The father has blood group $AB$ and mother $‘O'$. The child is supposed to have which of the following bloodgroups

$‘A'$ or $‘B'$

$‘A'$ only

$‘B'$ or $‘O'$

$B$ only

Solution

(a)When the blood group of one parent is $AB$ and that of other is $O$ then the child may have blood group either $‘A’$ or $‘B’$ as blood group $‘O’$ has no dominant genes for antigens.
