Blood type correspondence

[Journeyman]

Does anybody know the correct correspondence between the blood-typing systems in America versus Russia?

America has types o, A, B, and AB (both + and - for each).

Russia as types 1, 2, 3, and 4.

What are the exact correspondences?  Is the sequence the same?  O is 1, A is 2, B is 3, and AB is 4?

Yes, as you might have guessed, the question is connected to the antibody issue and childbirth.

I see that types A and AB are little more prevalent in Russia and Ukraine than in western Europe and America.
