Why is it that Rh incompatibility can be a serious problem when anRh-negative mother is carrying an Rh-positive fetus, but ABOincompatibility between mother and fetus is usually no problem?That is, a type A mother can usually safely carry a type B fetus.(Hint: The antibodies produced by an Rh-negative mother againstthe Rh antigen are usually IgG, whereas the antibodies producedagainst the A or B antigens are IgM.) Because the Rh antigenobviously serves no vital function (most humans lack it), why do youthink it hasn’t been completely eliminated during human evolution?
