Question

if a man is rh+ and women is rh- their child will survive or not

Answer 1

if a woman who is Rh negative and a man who is Rh positive conceive a baby, there is the potential for a baby to have a health problem. The baby growing inside the Rh-negative mother may have Rh-positive blood, inherited from the father.

Approximately half of the children born to an Rh-negative mother and Rh-positive father will be Rh positive.

Rh incompatibility usually isn't a problem if it's the mother's first pregnancy because, unless there's some sort of abnormality,the foetus's blood does not normally enter the mother's circulatory system during the course of the pregnancy.However, during delivery, the mother's and baby's blood can intermingle. If this happens, the mother's body recognizes the Rhprotein as a foreign substance and might begin making antibodies (protein molecules in the immune system that recognize, and later work to destroy, foreign substances) against the Rh proteins.

Rh antibodies are harmless until the mother's second or later pregnancies. If she is ever carrying another Rh-positive child, her Rh antibodies will recognize the Rh proteins on the surface of the baby's blood cells as foreign, and pass into the baby's bloodstream and attack those cells. This can lead to swelling and rupture of the baby's RBCs. A baby's blood count can get dangerously low when this condition, known ashemolyticorRh diseaseof the newborn, happens.

Answer 2

If a man is rh+ and a woman is rh- then their child will survive and nothing would happen to the child
If rh+ baby is born to a rh- mother then he may suffer from erythroblastosis foetalis but it generally occurs on conceiving a consecutive second rh+ child
