What happens when serum containing b antibodies is added to red cells carrying the b antigen? will the same thing happen if serum containing b anitbodies is added to red blood cells carrying the a antigen?

Explanation:

The blood agglutinate or clots

This does not happen when serum containing B antibodies is added to red blood cells carrying the A antigen because an antibody reacts only with its specific antigen and no other.
