Question

If a rh- man marries a rh+ woman what happens to The child ? Will the child survive or not?

Answer 1

Dear student,,If the mother is Rh positive that means on her red cells there is a protein for D and the father is Rh negative means his cells don't have that D protein (he's recessive). Depending on the mother's genotype (homozygous,DD, or heterozygous,Dd) the baby will determine the baby's Rh. If she's heterozygous the baby has a 50/50 chance to be born Rh positive or Rh negative. This is important to know because the Rh antibodies can kill a baby. Antibodies fight off anything that is foreign to the host. If the baby is the mother's first child and is Rh negative the doctors needs to know this to keep the mother from making antibodies that could harm the baby by giving her someting called Rogram, which fools the body to think that antibodies are already made and so won't develop any. This is important if the mother plans to have more than one child. If she doesn't take Rogram and has a second child any antibodies that the mother developed from the first baby will harm the second baby.
