No.. This is not a case of two positives make a negative.
The virus would be passed on to the unborn child.
It takes two rh negative parents to produce an rh negative baby.
the baby may be A or O.
here
yes if both are heterozygotes
a negative times a negative is a positive so the answer is positive
Definitely. One Rh positive parent is at least 50% likely to produce Rh positive offspring.
HDN only occurs in rhesus negative women who have been sensitized by positive blood. Rhesus positive mother can have a rhesus negative baby. In rhesus positive group, they have the antigen Rh. When this antigen from baby enters mother's blood circulation, because of inutero bleed in pregnancy; mother's blood cells will react to the foreign antigen and produce antibodies which are harmful to the baby's blood cells when they cross the placenta and enter baby's blood stream. These antibodies will break baby's blood cells down causing haemolytic disease. Whereas in rhesus positive mother with negative baby, if baby's blood enters mother's circultaion it will not produce any antibodies as there are no antigens in Rh negative blood. And if mother's blood mixes with baby's blood in the womb, baby will not have the ability to produce antibodies as their immune system is not developed. So there is no chance for haemolytic disease.
If the fetus is O positive, there will be no problem. If the fetus is O negative and is the first O negative baby, nothing will happen to it, but the subsequent O negative fetuses will be miscarried unless the mother takes some special injections during this pregnancy.
Negative is recessive...you can have a negative also.
I'll wait for you to ask the question. Positive parents can have a negative baby as positive is dominant so they may both have one positive and one negative gene and the baby gets the two negative genes.
The mother will be given Rhogam injection within 72 hours to prevent formation of antibodies to protect the 2nd baby that he will be conceiving.
No. There's a small chance the baby will be O negative--if both parents have an Rh negative (recessive) allele, and the baby inherits this allele from both parents, the baby would be Rh negative. But if the baby inherits the Rh positive allele from either parent, the baby will be Rh positive.
