Detailed explanation-1: -85% percentage of world population has Rh positive blood.

Detailed explanation-2: -Most people are Rh positive, meaning they have inherited the Rh factor from either their mother or father. If a fetus does not inherit the Rh factor from either the mother or father, then the fetus is Rh negative. When a woman is Rh negative and her fetus is Rh positive, it is called Rh incompatibility.

Detailed explanation-3: -Rh factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you’re Rh positive. If your blood doesn’t have the protein, you’re Rh negative. The “+” or “–” you might see after your blood type refers to Rh positive or Rh negative.

Detailed explanation-4: -If your baby’s father is Rh positive, however, there’s a significant possibility that your fetus will inherit the Rh factor from him, creating an incompatibility between you and your baby. This incompatibility is usually not a problem in a first pregnancy because you don’t have antibodies to the baby’s Rh factor yet.
