A, B, AB, and O.
The four main groups are... Group O+ (the commonest), group A+, group B+ and group AB+

According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null). Blood group A If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma. Blood group B If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. Blood group AB If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma. Blood group 0 If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.
The Duffy blood group system is a method of categorizing human blood types through the Fy antigens found on the surface of red blood cells. There are 4 of such blood types.
A, ab, b and o
They are the red blood cells,white blood cells,platelets and plasma
Blood group A can donate and receive blood from blood group A. Blood group B can donate and receive blood from blood group B. Blood group AB can donate only to blood group AB and receive from any other blood group (they are universal recipent) Blood group O can donate to any other blood group ( they are universal donor) and can receive from only blood group O.
There are four main blood groups: A, B, AB, and O. These also have a negative and a positive, I.e A+, A-, and so on. This would mean that there are eight different types of blood group: A+ A- B+ B- AB+ AB- O+ O-
