Solve this:

133. A man with B blood group marries a woman with AB blood group. Which blood group will never appear among the progeny :-

(1) O                               (2) AB
(3) A                               (4) B

Dear student.

The correct answer is (1) O

The cross is shown below:
 

First Condition:
IAIB  x IAIO -- IAIA ,  IAIO ,  IAIB , IBIO.


Second Condition.
IAIB  x IAI --  IAIA ,  IAIIAIB , IBI.

So there will be no O blood group.

Regards.
