Does blood type change? Can blood type change?

A person's blood type does not change throughout their lives, while a human blood type evolves with changes in factors such as the environment.

Take the ABO blood group system as an example:

Blood type O has the longest history. It appeared around 60,000 to 40,000 B.C., when Neanderthals ate a simple diet: weeds, insects, and predators that fell from trees ate the leftover fruit.

And 40,000 years ago, the Cromanon people appeared, and they lived by hunting. After hunting all the big beasts, they moved from Africa to Europe and Asia.

Blood type A appeared between 10,000 and 10,000 BC. At that time, our fruit-based ancestors gradually became omnivorous. Over time, farming became the main mode of production for the people living in present-day Europe, wild birds and beasts began to be domesticated, and the diet of people changed.

Even now, the vast majority of people with blood type A live in Western Europe and Japan.

Blood type B appeared between about 10,000 BC and the New Era. At that time, parts of East Africa were forced to migrate from the savanna steppes to the cold and barren Himalayas. Climate change is a major factor in the development of blood type B.

This blood type first appeared in the race, and as they continued to migrate to the European continent, many Eastern Europeans today share this blood type.

AB blood type is the latest to appear, it appeared less than 1000 years ago, and it is a relatively modern blood type. It is mainly produced by the fusion of Indo-European peoples who "carry" blood type A and Mongols who "carry" blood type B. People with AB blood type inherit the ability to tolerate disease, and their immune system is more resistant to bacteria, but they are susceptible to malignant tumors.

No. blood groups blood types) is 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. In fact, 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, and at the same time, the discovery of animal blood group also provides new problems and research directions for blood group research. Blood groups are generally divided into four types: A, B, AB, and O, and there are more than 10 blood group systems such as RH, MNS, P, etc., which are extremely rare.

Among them, type AB can accept blood transfusion of any blood type, so it is called a universal blood recipient, and type O can be exported to people of any blood type, so it is called a universal blood transfusion, abnormal blood person, in fact, the transportation between different blood types can generally only be delivered in small amounts, not in large quantities. If you want a large amount of blood transfusion, it is better to have the same blood type.

Generally not, but it has been reported that blood type changes occur in patients with blood disorders for a long time, but this may also be a low-probability event.

Probably not, it's up to your DNA.

Blood type is determined by specific genetic material, just like planting melons and getting beans, so once the blood type is determined, it does not change on its own. However, when certain diseases (leukemia) occur in the human body, especially in the middle and late stages of the disease, immature red blood cells enter the bloodstream in large quantities due to the dysfunction of the hematopoietic organs. The blood group antigens on the membranes of these immature red blood cells are either reduced or disappear, so the blood group changes.

If the function of the hematopoietic organs is restored, then the changed blood type can show the prototype again. In addition, there may be temporary changes in blood type after long-term massive blood transfusions, but this change will not last long.

Do it once. Test it out.

Look at Ran Tan to see what kind of blood type the potato duancong is!

Maybe you said it yourself is A.

Are you so sure? The blood type number Sakura doesn't change!
