Can a b positive and a o nagitive have a a positive baby?
Yes. An O neg parent can only pass on an O Blood Group gene and a Rhesus Negative gene. A B pos parent can potentially pass on a B or an O Blood Group gene and potentially a Rhesus negative or positive gene. Statistically your baby would have a 75% chance of being a B blood group and 25% of being an O. Also, 75% likely to be a positive baby and 25% likely to be a negative baby.
Why does haemolytic disease of the newborn not occur in rhesus positive mothers with a rhesus negative baby?
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.
Can a parent with A positive and a parent with O positive have an A negative baby?
No
Can two parent with A and a parent with AB positive and have O negative baby?
No.
Can a O negative parent and an RH O negative parent make a positive baby?
yes
What blood type will the child be with parents blood type O positive father and mother O positive?
The baby can only be an O Blood Group as both parents can only be carrying 'O' type genes. The baby would have a 75% chance of being an O positive and a 25% chance of being an O negative. This is because the mother can only pass on a Rhesus negative gene but the father might either have two Rhesus positive genes or one Rhesus positive and one Rhesus negative. If the first is true the child will only be O positive, if the second is true it could be O positive or O negative depending on which gene the father passes.
What problems might occur if a mother is rhesus-negative and the father is rhesus-positive?
It is possible for there to be problems with a pregnancy. If mother's blood type is negative and the father's is positive, and the baby is positive, her blood type may begin to attack the child. Make sure she checks with her doctor regularly during a pregnancy.
Is there a problem for the baby when the father is rhesus negative and the mother is rhesus negative?
No.there is no problem.Because both male and female are unable to produce rhesus antigen and there is no prouction of antibody inside the baby blood.
Technique of exchange transfusion in jaundice what should be the blood group and rhesus factor to be used for exchange transfusion in a group a rhesus positive baby of a rhesus negative mother?
If the baby has already been born then you can transfuse A RH POS to the baby. If the baby is still in the womb I would think A RH NEG would be right.
Father has b positive and mother o negative can the baby be a negative?
No, the baby cannot be A-. A and B genotypes are codominant and O is recessive. Since the father is B and not AB, his genotype must be either BB or BO. The mother is OO. So there is no way for them to have an AO or AA baby. The baby can be Rhesus negative however, because the father may be heterozygous for the Rhesus factor.
What blood type will the child be with parents blood type o negative mother and father o positive?
The baby can only be an O Blood Group as both parents can only be carrying 'O' type genes. The baby would have a 75% chance of being an O positive and a 25% chance of being an O negative. This is because the mother can only pass on a Rhesus negative gene but the father might either have two Rhesus positive genes or one Rhesus positive and one Rhesus negative. If the first is true the child will only be O positive, if the second is true it could be O positive or O negative depending on which gene the father passes.
Can A positive mother O positive father can give A negative baby?
yes that's possible because A is dominant on O so the baby could have A (but not necessarily). negative is possible. it would mean that both parents have Dd as a rhesus factor.
