Only by adoption....
A person's blood type in the ABO system denotes the presence or absence of the A and B antigens. The antigens are molecules on the surface of the red blood cells;
Group A people have the A antigen
Group B people have the B antigen
Group AB people have both A and B antigens
Group O people do not have A or B
Each person has two genes controlling their ABO blood type; one they inherit from their mother, and one from their father. The A and B genes, if present, will always be expressed, so it is possible to have an A gene and an O gene, but the blood type will be A.
If a person is group O, then they have two O genes. If two people who are group O have a baby together, the baby will only inherit the O gene from each parent and will therefore be group O.
