Answer 1

Human blood is grouped into four types: A, B, AB, and O. Each letter refers to a kind of antigen, or protein, on the surface of red blood cells.

There are 4 main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total there are 8 blood groups.

Answer 2

Answer:

The four blood groups are O, AB, A, B.

They are named on the basis of the RH factor of the blood group and can be classified into negative and positive groups.
