What are the differences in people s blood types?

ABO blood types can be divided into 4 blood types: A, B, AB, and O. Red blood cells containing A antigen and H antigen are called type A, and type A contains anti-B antibodies in human serum; Red blood cells containing B antigen and H antigen are called type B, and type B contains anti-A antibodies in human serum; Red blood cells contain A, B, and H antigens, which are called AB types, and people with this blood type do not have anti-A and anti-B antibodies in their serum; Red blood cells have only H antigen, called type O, and type O contains anti-A and anti-B antibodies in human serumSee.

Blood typing is usually based on red blood cells.

is based on the presence or absence of certain heritable antigenic material on the surface of red blood cells. The most common blood group system is the ABO blood group system and the RH blood group system, the ABO blood group system divides human blood groups into type A, type B, type O, and AB type, and the difference between these 4 blood groups is blood type A.

It means that the surface of the red blood cell membrane expresses A antigen, and its serum does not express B antibody.

Blood groups are classified according to the type of antigen they contain on the surface of red blood cells. The blood type is different, and I think the blood is just a classification of different blood, and there is not much difference in nature.

ABO blood group is based on whether there is antigen A and antigen on the red blood cell membrane, B will divide the blood into 4 blood groups, and different blood types contain different antibodies; The A standard selection system will distinguish the selection of human beings into type A, type B, type O, and type AB, different types contain different antibodies, type A blood refers to the A antibody expressed on the surface of the red blood cell membrane, and the serum does not express B antibody, and the blood type B refers to the red blood cell membrane expressing B antibody, and the serum does not express A antibody.

First of all, blood groups are classified according to the different types of antigens contained in the surface of red blood cells, which means that different types of red blood cell surfaces contain different markers in different blood types. In fact, the human blood group system is very large, and there are only two blood group systems that we commonly use, one is the ABO blood group system, and the other is the rare blood group Rh system. This is one of the more common blood group systems in clinical practice, and clinical transfusions are based on this blood group marker to determine whether a patient can receive a blood transfusion**.

When it comes to blood type, many people can think of blood transfusions. Because only the same type of blood can be delivered to someone else's body to achieve the effect of first aid. But what exactly is the basis for the classification of blood types? How to be sure that this blood type is what you need, let's take a look.

There are four main blood types in the ABO blood system, namely A, B, O and AB. Red blood cell marker responses are used to determine whether a patient can receive a blood transfusion of the same blood group. If it is a blood atypia interaction, it must be used under professional tools and tests, otherwise there will be a hemolytic reaction, and the rescue will be ineffective and death.

There are two types of rare blood types, Rh blood type, negative and positive, most rare blood types are positive, and some Rh negative are called panda bloodEven in the blood bank, the blood type is often in emergency. In order to protect the blood supply of pandas, there is a special archive in China, which shows that its blood type is rare.

What is the difference between different blood types?

Different blood types just react differently to antigen reagentsIt is difficult for blood to see its changes in the human body on its own, and it is not visible to the naked eye. Moreover, the blood type is different, and it has nothing to do with personality, IQ, etc., it is only a part of the human body and does not affect genetic inheritance.

However, in general, parents with blood type A can only give birth to the next generation of type A, and the next generation of mixed blood types such as mother type A and father type B will have three possibilities, namely type A, type B, and type AB. Blood type O is special, and antigen tests are required after pregnancy to prevent hemolytic anemia.

Blood groups A genetic trait that manifests itself in the form of blood antigens. In a narrow sense, blood group refers specifically to the difference in red blood cell antigens between individuals; However, it is now known that in addition to red blood cells, there are antigenic differences between individuals in white blood cells, platelets, and even certain plasma proteins. Therefore, blood grouping in a broad sense should include the differences in antigens of each component of the blood between individuals.

Blood group has a wide range of practical value in anthropology, genetics, forensic science, clinical medicine and other disciplines, so it has important theoretical and practical significance.

Blood Group System The red blood cell blood group was discovered in 1900 by K. Landsteiner in Austria. He cross-mixed each person's red blood cells with someone else's serum, and found that the existing blood had a clotting reaction with each other, while the other did not. He believed that in the case of agglutination, there is an antigen on the red blood cells and an antibody in the serum.

If the antigen and the antibody have a specific relationship, agglutination occurs. If there is an antigen A on red blood cells and an antibody on serum, agglutination will occur. If red blood cells lack an antigen or a corresponding antibody in the serum, agglutination does not occur.

Based on this principle, he discovered the ABO blood group of the person. Later, he injected red blood cells from different people into rabbits, and produced three kinds of immune antibodies in rabbit serum, called M antibodies, N antibodies and P antibodies. With these three antibodies, three new antigens on red blood cells can be identified.

These new antigens are independent of ABO blood group and are inherited independently of each other's blood group system. And m, n, and p are not one system. The blood group genes that control different blood group systems are on different chromosomes, and even on one chromosome, the gene loci of the two systems are very far apart, not linked, and therefore inherited independently.

A, B, O, AB blood group It is best to choose the same type of transfusion, the antibodies on the red blood cell membrane of people with different blood types are different, and indiscriminate blood transfusion will produce antigen and antibody reactions, resulting in red blood cell agglutination, which may be life-threatening. There is also a rare group of people with Rh-negative blood, and people with this blood type can be considered only A, B, and O blood types without considering Rh blood type for the first blood transfusion, but must be considered for the second time and later.

There are many ways to classify human blood types. The most commonly used of these is the RBOC ABO blood group system. If blood groups are classified according to the ABO blood group system, an individual's blood group is divided into four types of blood types A, B, AB, and O based on the blood group antigens on the red blood cell membrane.

Depending on your parents' genes, you first need to understand what the genes of each blood type are: type A - AI gene, type B - BI gene, AB type - AB gene, type O - II gene. This involves the question of genetic recombination, you can search for specific how the gene is recombined, and your question can be answered!

Your dad is xy and your mom is xx

Half of each of them is you.

There will be a total of 4 situations:

x+x=xx x+x=xx y+x=xy y+x=xy, if it's xx, you're going to be a mother.

If it's xy, you're going to be a dad.

In a word, blood type is determined by the parents.

It is determined by the chromosomes of the parents.

Please be clear. I don't know what your title means.
