Detailed explanation-1: -blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.
Detailed explanation-2: -Individuals who are homozygous for null alleles at this locus (h/h) do not produce H antigen, and because the H antigen is an essential precursor to the ABO blood group antigens, they cannot produce A and B antigens. Therefore, their serum contains anti-A and anti-B, in addition to potent anti-H.
Detailed explanation-3: -A small number of antigens and antibodies are responsible for the ABO blood types. The specific combination of these components determines an individual’s type in most cases. Blood group O has no antigens, but has both anti-A and anti-B antibodies in the plasma, as well as some special “anti-A, B” antibodies.
