Concept:Rh incompatibility between an Rh-positive father and an Rh-negative mother can cause problems in pregnancy, especially in later pregnancies.
Explanation:If the baby inherits the Rh-positive gene from the father, the Rh-negative mother may be exposed to Rh-positive blood.
The mother’s body then produces antibodies against Rh-positive blood.
In a later pregnancy with another Rh-positive baby, these antibodies can cross the placenta and destroy the baby’s red blood cells.
This leads to severe anaemia, jaundice, and possible stillbirth.
The first Rh-positive baby is usually unaffected, but the risk increases with each subsequent pregnancy.
