Modes of Inheritance

April 18, 2010 in O negative Information

In more than 98% of cases, the red blood cell incompatibility involves the Rhesus or Rh D antigen[Rh-negative Factor] so the disease is known as Rhesus disease or Rh disease. Although the exact percentage varies with race, 15% of the United States population is Rh-negative and 85% is Rh-positive. If a Rh-negative woman conceives a child with a Rh-positive partner, the potential exists for the child to inherit its father’s Rh-positive blood type.[ There are two types of Rh-positive men. In 55% of individuals, the man is heterozygous. In this situation, his genetics allow him to produce Rh-negative offspring 50% of the time and Rh-positive offspring the remaining 50% of the time. In the second type of a Rh-positive= individual, homozygous state.]

So… Rh-negative women with a Rh-positive partner are at RISK of spontaneous miscarriage and other fetus REJECTION events. Hmmmm And a Rh-negative woman with a Rh-negative partner has even a smaller chance of having a Baby born alive! Hmmmm… In animals this is seen as a problem, in HYBRID Animals.

Rh-negative women and men have several “Unusual Traits” that Rh-positives don’t.

i am O- my husband is O+, Both my girls came out being o- whereas mys on o+. ( no miscarriages)I never had a problem with my first preg my body tried to reject the baby. My second preg I had to be give the RH shot because I had started to spot.
My third preg, I started having early contractions at 20 wks. All the research I’ve done has stated the only time the the female will reject baby is if the baby is not the same blood type as the mother.

If you are rhesus negative and your partner is rhesus positive, then your unborn child could inherit either negative or positive blood – you wont know until birth. However if the mother is negative and the baby happens to be positive (positive rhesus factor is dominant, negative rhesus factor is recessive), then this may cause problems for any future pregnancies the mother may have. Your first baby will be fine. Problems can occur if the baby’s positive blood manages to find it’s way into the mother’s bloodstream, either during pregnancy or labour, mixing with her negative blood. If this happens… Read more »

Anyone know of any examples of this? I know the thread is old , but it sounds interesting!

Hi Jill,

“Unusual Traits” is put in quotes because it is not scientifically supported claim.
You can entertain yourself with this reading: Rh-Negative Blood Type Traits and Characteristics
