In this way, can Rh factor cause miscarriage?

how is Rh factor inherited? The Rh factor genetic information is alsoinherited from our parents, but it is inheritedindependently of the ABO blood type alleles. There are 2 differentalleles for the Rh factor known as Rh+ and Rh-. Justlike the ABO alleles, each biological parent donates one of theirtwo Rh alleles to their child.

Beside above, what happens if the mother is Rh positive?

If the mother is Rh-negative, her immune systemtreats Rh-positive fetal cells as if they werea foreign substance. The mother's body makes antibodiesagainst the fetal blood cells. These antibodies may cross backthrough the placenta into the developing baby. They destroy thebaby's circulating red blood cells.

What blood type is dangerous for pregnancy?

What Increases Your Risk. Rh sensitization canoccur when a person with Rh-negative blood is exposed toRh-positive blood. During pregnancy, an Rh-negativewoman can become sensitized if she is carrying an Rh-positivefetus.
