Question

How can we decide the blood group of a person

Answer 1

Depending on which of these genetically determined proteins or antigens, known as red blood cell antigens, you inherited, you will have one of four blood types: type A, type B, type AB or type O. If you have type A blood, your red blood cells have the A antigen, and your body will produce anti B-antibodies.

Answer 2

We ourself can't decide the blood group of a person. It depends on the genes transferred by our parents to us at the time of birth......... If parents have A and B blood group then the child's BG will be A, B, AB or O ......... If parents have A and Ab as BG then the child's BG will be either A, B or AB ................... If both parents have B blood group then the child's BG will be either B or O............
