Cases of reactive factor in the blood.. The difference in the mother's blood from the fetal blood in terms of the reactive factor leads to the formation of antibodies and to the disruption in the distribution of oxygen and immaturity of blood cells

Cases of the reactive factor in the blood:
A condition of mental weakness linked to the blood of the mother from the blood of the fetus in terms of the factor Raysi, a component of blood and is determined genetically. If both the mother and the father are negative or positive, there is no problem. If both mother and father are different, this results in the formation of antibodies, disruption in the distribution of oxygen, immaturity of blood cells, and destruction of red blood cells at the embryos. In the formation of the brain, which may result in brain damage and mental impairment and perhaps the death of the fetus and abortion or death shortly after birth.
