Detailed explanation-1: -Type AB blood has both A and B antigens, and type O blood has neither A nor B antigens. Your immune system will produce antibodies against any blood antigens you don’t have in your own blood.
Detailed explanation-2: -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. But assigning a letter is just the first step in determining your specific blood type.
Detailed explanation-3: -O has neither A nor B antigens on red blood cells.
Detailed explanation-4: -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.
