Detailed explanation-1: -blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.
Detailed explanation-2: -Type O negative blood is the only blood type with no antigens. Blood type A has an A antigen, while blood type B has a B antigen. Blood type AB has both A and B antigens. Blood type O has neither.
Detailed explanation-3: -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-4: -People with type A blood have anti-B antibodies. People with type B blood have anti-A antibodies. Type O blood contains both types of antibodies. The 2 steps above can accurately determine your blood type.
