Name all of the possible human blood types using both the ABO and Rh blood groups together.

Answer 1

Human blood grouping is mainly based on the antigens present on their RBC (red blood cells) and in plasma into various groups but the main antigens are namely A/B and Rh antigens.

Depending on A/B antigens humans are grouped (ABO Grouping) into

A group: those having A named antigen on their RBC.

B group: those having B Antigen on their RBC.

AB group : Those having both A B antigens on their RBC.

O group: those having no antigens on their RBC.

Depending on the presence of Rh antigens they are grouped into Rh positive or negative group.

So if the person has both A and Rh antigens then he will be A positive blood group. But having only A antigen but not Rh Antigen then he will be A negative group.

Extra Information:

In addiition to these there is also the HH group. The peculiarity is that they do not express the H antigen. As a result they cannot form A antigens or B antigens on their red blood cells. Thus they can donate blood to anybody with ABO grouping but can receive blood only from Bombay blood group people.
