O+
Little fact for you. Interestingly I found out blood type is determined, in part, by the ABO blood group antigens being present on red blood cells. Group O has no A or B antigens present at all hence why it is called "O" to start with, and is often called '0' (zero, or null) in other languages because of this.
My blood serum contains IgM anti-A and anti-B antibodies that work against the A and B blood group antigens. Because of this "compatibility issue" I may donate my blood to A+, B+ and AB+ recipients but can only receive blood from another individual with either O− or O+ and since my mother is O− I cannot undergo blood transfusion for her if it were a matter of life or death. O− bloodtypes are invaluable in that any other blood type can become a recipient but they themselves are vulnerable in that they can only accept another O− individual as their donor.
Intelligent Design my arse.
