The Rh negative rate of Han people in China is 0.34%, and most of them are Rh positive, so the blood transfusion reaction caused by Rh blood group incompatibility is relatively less than ABO blood group. RH blood group is a very important blood group classification, although it is not as well known as ABO blood group. Then everyone must want to know what is the genetic law of RH blood group!

Rh(D) blood type is only positive and negative (positive and negative), and so is its inheritance.

Genetic law of Rh(D) blood group;

Parents' Rh(D) blood group: positive+positive children's Rh(D) blood group: positive/negative;

Parents' Rh(D) blood group: positive+negative children's Rh(D) blood group: positive/negative;

Parents' Rh(D) blood group: negative+negative children's Rh(D) blood group: negative.

There are some rare exceptions, such as pathological changes and genetic variation, which can lead to the incompatibility between children and their parents. The most accurate method of paternity test is DNA analysis and testing to directly check whether the genetic mode of genetic material itself conforms to Mendel's genetic law.
