Hi, thanks for using Chat Doctor There are consequences of such a union.IN terms of blood groups sometimes when a female whose blood group is rhesus negative (O neg or AB neg or A neg or B neg) marries a man whose group is rhesus positive (O positive /AB positive/ B positive or A positive), issues can arise. When the woman conceives, some babies blood may enter the blood stream and the female would react to it and form antibodies against it. Because of this, there may be problems with subsequent pregnancies. Other than this, the blood group does not matter. I hope this helps
