Individuals either have, or do not have, the Rhesus factor (or Rh D antigen) on the surface of their red blood cells. This is usually indicated by 'RhD positive' (does have the RhD antigen) or 'RhD negative' (does not have the antigen) suffix to the ABO blood type. Unlike the ABO antigens, the only ways antibodies are developed against the Rh factor are through placental sensitization or translation. That is, if a person who is RhD-negative has never been exposed to the RhD antigen, they do not possess the RhD antibody.[1] The 'RhD-' suffix is often shortened to 'D pos'/'D neg', 'RhD pos'/RhD neg', or +/-. The latter is generally not preferred in research or medical situations, because it can be altered or obscured accidentally. There may be prenatal danger to the fetus when a pregnant woman is RhD-negative and the biological father is RhD-positive.
The father's blood type could be either A positive or A negative. The children inherited the A antigen from the father, resulting in their blood type as A negative. The Rh factor (positive or negative) is inherited separately, so the father could be either positive or negative.

Yes, it is possible to have healthy children with blood group O positive and B negative. The Rh factor (positive or negative) only becomes a concern during pregnancy if the mother is Rh-negative and the father is Rh-positive. In this case, the mother may need to receive certain treatments to prevent complications during pregnancy for subsequent pregnancies. It is recommended to consult a healthcare provider for personalized advice.
Yes, it is possible for parents who are AB positive and B positive to have a child who is A negative. This is because a child can inherit one A and one Rh negative gene from the parents, resulting in blood type A negative.
Yes, it is possible for an A positive mother and a B positive father to have an O negative child. This can happen if both parents are carriers of the O negative blood type, which can be inherited from ancestors. In this case, the child would inherit one O gene from each parent, resulting in an O negative blood type.
Yes.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
The father's blood type could be either A positive or A negative. The children inherited the A antigen from the father, resulting in their blood type as A negative. The Rh factor (positive or negative) is inherited separately, so the father could be either positive or negative.
