Will have AB blood type And people who have no A and B Antigen, will have O blood types Our imun system or antibody will read our antigen in this blood cell. If our antibody found a different blood cell from our original blood cell Antibody will think that was dangerous object to our body and will against them This against reaction, will inflict blood clotting and result DEATH.
