What happens if father is Rh( negative) and mother is Rh(positive)??
How does it affect the sebsequent child ????
Possibilities for the Rh status of child from Rh- father and Rh+mother .
If mother is homozygous for Rh+, then all childs will definitely be Rh+.
If mother is heterozygous for Rh+ then child can either be Rh+ or Rh- .
Mother is Rh+ then having Rh+ blood of the fetus will not be foreign (antigen) so no antibodies will be produced against each other.
If developing child is Rh- and mother is Rh+, then mother will recognize fetal blood as foreign molecule (antigen) and will produce antibodies against it that kill fetus, leading to stillbirth.
