O blood type and B blood type

As the development of modernization is constantly improving, people's quality of life is also constantly improving, people's living standards are also constantly improving, and people's pace of life is also constantly accelerating. It is precisely because of this situation that people know more about things, and these things are more meaningful to themselves. O type blood and B type blood are one of them.

As for O type blood and B type blood, in fact, they are quite common in every country and nationality, so people don't need to worry too much. The following is some information about O type blood and B type blood, and I hope everyone can make good use of it.

my country is the first country in the world to study blood types. As early as the Three Kingdoms period, there was a "blood test method" to confirm blood relationships. According to Dr. Song Jieping from the Genetics Center of Hubei Provincial Maternity and Child Health Hospital, human blood types vary greatly and are very complex. The four blood types we usually talk about, A, B, O and AB, actually belong to a blood type system called the ABO blood type system.

It has been discovered that humans have 26 blood type systems, and each blood type system has a varying number of blood types. However, among these blood type systems, the ABO blood type system was discovered the earliest and has the greatest impact on humans. Blood type has its own genetic laws. According to the genetic laws of blood type, if you know the blood types of your parents, you can infer which blood type your children may have and which blood type they may not have. This can provide some reference value in forensic paternity identification. Of course, the most accurate method at present is DNA testing.

In addition, understanding the genetic laws of blood type is also important for blood transfusion or treatment of blood diseases. As shown in the table, if both parents are O-type blood, the genetic relationship is the simplest and the child can only be O-type blood; when both parents are "A+B" type blood, the genetic relationship is the most complex and the child may have any of the four blood types: AB, A, B, and O. In addition, it is worth noting that when the blood types of a couple are incompatible, "hemolytic infant" may occur. Neonatologists say that the "hemolytic infant" phenomenon is more complicated. It generally refers to the mother being type O blood and the child being of another blood type. When the mother becomes pregnant with such a child, the child, as a "foreign body" in the mother's body, causes the mother to produce antibodies, which in turn destroy the child's blood cells, resulting in hemolysis. This situation can easily lead to premature birth, neonatal jaundice, etc. It is recommended that couples check their blood types before pregnancy so that intervention measures can be taken in advance.

Through the above understanding and introduction, I believe everyone can have a certain understanding of O type blood and B type blood. At the same time, I hope that everyone can be helped by the above knowledge. At the same time, I also hope that everyone can do more exercises suitable for themselves in their daily lives. At the same time, I also hope that everyone can develop a good habit of going to bed early and getting up early.
