Solutions

Expert Solution

The best answer from the given choices are Option-e- neither parents can have blood type AB.

Even if both the parents do not have AB blood type, it is possible to have a child with AB blood type

The following combinations can have chances of child with AB blood group.

Mother's blood type

A

B

A

AB

B

AB

B

Fathers blood type

B

A

AB

A

AB

B

AB

The other options are incorrect because

Opt-a- one parent can have blood type O. If one of the parent has O blood type then there is no chance of AB blood group, it can only be either A, B or O

Opt-b- both parents should have different blood types is partially true when you look into the table given above. But in case of both the parents with AB blood group , the child could still be AB blood group

Opt-c- both parents must have blood type AB. It is not mandatory that both the parents should be AB to have a child of AB blood type.

Opt-d-both parents can have any blood group is wrong
