What Are The Risks Of An A+ Boy Marrying An O-ve Girl?
It is safe to marry this girl
Detailed Answer:
Thanks for asking on HealthCareMagic. Our blood groups have two components of which one comes from father and the other from the mother. The commonly known blood groups A, B, AB and O actually have subgroups. So A can be AA or AO, B can be BB or BO, AB can only be AB, O is actually OO. Thus in case you are either AA or AO while your partner is OO. Your offspring can thus be either O (OO) or A (AO). With respect to the Rhesus factor similarly, depending on whether you are ++ or +- (both of which would give +), your offspring can be + (+-) or -.
Now coming to the specific problem that you have. There is no problem in marrying a girl with O-ve blood group. In case the child in case of first pregnancy gets +ve blood group, the mother would get exposed to +ve blood group and develop immune sensistivity which may affect the child of second pregnancy and may cause haemolytic disease or jaundice in the newborn. This is a preventable condition and a simple injection of anti-D gammaglobulin after the first pregnancy will reduce this risk.
So it is safe for you to marry this girl. Stay relaxed.
