Is panda blood divided into yin and Yang?

summary

Among the blood types of human body, panda blood is a kind of Rh negative blood. In our life, because there are very few people with this kind of blood, it is called extremely precious blood. Therefore, this paper discusses the causes of panda blood and its yin-yang nature? Share as follows.

Is panda blood divided into yin and Yang?

Factor 1: human genetic material is mainly in the "chromosome". Generally speaking, there are two sets of cells in human chromosome, and this situation is mostly caused by the inheritance of parents. The two sets of chromosomes of Rh negative people are all Rh negative genes; In RH positive blood, at least one of the two sets of chromosomes has a RH positive gene. When everyone inherits downward, they inherit only one set of chromosomes.

Reason 2: so if your mother and father have two sets of chromosomes, only one of them has RH positive gene; The other set is Rh negative gene, so both of them are RH positive, but if they are both Rh negative genes, you will be Rh negative. So this kind of inheritance is common recessive inheritance, not intergenerational inheritance.

RH negative blood, also known as panda blood, refers to Rh negative blood. It is a very rare blood type. Because it is extremely rare, it is called "panda blood". RH negative blood is the common name of Rh negative blood group. Human erythrocyte blood group consists of more than 20 blood group systems. ABO and Rh blood groups are the two blood group systems most closely related to human blood transfusion. When there is a kind of D blood group substance (antigen) on a person's red blood cells, it is called RH positive, which is expressed by RH (+); When D antigen is absent, it is Rh negative, which is indicated by RH (-). The distribution of Rh (-) varies greatly among different races, and the proportion of Rh (-) is relatively high among Caucasians, about 15%.

matters needing attention

In China, more than 99% of Rh blood group patients are positive, so hemolytic reaction due to Rh blood group incompatibility is rare. But less is not equal to No. If the recipient of Rh negative blood group transfuses RH positive blood group, it will cause immune hemolytic reaction. The correct way is that the blood type of the recipient and the donor should be the same, that is, they are all Rh negative.
