    Hello sir. ..It's important to know your genotype so that you don't have babies with sickle cell disease..Two carriers of the sickle cell gene should avoid having babies...e.g AS and AS or AS and SS. Secondly with the blood group, the only worry is a woman who has a negative rhesus group marrying a man with a positive rhesus group.however if this is know,prior to marriage or during the woman can get a rhogham injection during pregnancy to prevent subsequent pregnancies from having any problems. e.g Man with O+/A+/B+/AB+ and woman with O-/A-/B-/AB-...Blood group rhesus difference shouldn't stop a couple from getting married. I hope

    What kind of problems can the babies have? Also can a man have a negative Rhesus group or is it just women that bleong to that category?

    Hello again...yes a man can have a negative rhesus group but it has no medical consequences. in fact most people are rhesus postive.the problem only arises when a rhesus negative woman marries a rhesus postive man and she goes on to have a rhesus postive child. The baby can develop what's called hemolytic disease of the new born.it can be mild with the baby needing blood transfusions and it can be severe enough to cause hydrops foetalis or still births.its prevented with rho ham injections to the mother at 28 weeks and or 34weeks. It can also be given within 72 hrs of delivery of first child.
