Who is the panda blood in the zodiac?
Rh-negative blood, commonly known as panda blood, is the first two letters of mbth, a macaque. Human red blood cell 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 a person's red blood cells have blood group D substances (antigens), it is called Rh positive, which is expressed by RH (+); When the D antigen is missing, it is Rh negative, which is expressed by RH (-).
How rare is panda blood?
People's blood type is usually determined by some heritable glycoproteins and sugar chains on the surface of red blood cells. So far, more than 30 such blood group systems have been discovered. For example, the ABO blood group system that we are most familiar with is composed of A, AB, B and O, and the Rh blood group system is the most complicated among the classified red blood cell blood group systems. In Rh system, if the surface of red blood cells contains D antigen, it is called RhD positive, and vice versa.
Existing scientific research has found that the population with RhD positive accounts for the vast majority of the world population, while the population with RhD negative is very few. For example, in Asia, more than 99.5% of people are RhD positive, and less than five thousandths of people are RhD negative, so it is called "panda blood".
