Question

Barry has type O+ blood. His wife Anna has type A+ blood. Which type of antibodies would be present in both Barry’s and Anna’s blood?

Answer 1

Barry's antibodies are ab while Anna's antibodies are b

Answer 2

Barry must have anti A anti B antibody and Anna must have anti B antigen.

Explanation:

A, B, AB, and O are the blood group present in humans. The person who has A blood group have A antigen and anti B antibody. A person with blood group B has B antigen and anti A antibody. AB blood group persons and both A and B antigen but no antibody and persons with O blood group have no antigen both anti-A and B antibodies.

Therefore if barry has O+ blood group than he must have anti-A and anti B antibodies and as his wife has A blood group than she must have anti B antibodies.
