Whose offspring is ab blood?

Type AB is a new blood group produced by mating between Caucasians of type A and Mongolians of type B.. In the blood group research before 1, 000 years ago or 1, 200 years ago, AB type did not exist, and it was the latest and rarest blood group, accounting for only about 5% of the total population.

AB blood group is a kind of blood group, which means that the serum does not contain anti-A and anti-B antibodies. Although there are corresponding antigens on blood cells of AB blood group, because blood cells are mainly imported and there is little serum, little lectin is imported, and the combination of lectin and antigen is relatively safe.

Type AB blood is called universal recipient, but the amount of blood transfusion should not be too large. It can only be used in emergencies (such as the battlefield), and the safety factor is not high.

Introduce four blood types:

Blood type O is the first blood type of human beings. In order to survive, our ancestors constantly struggled with wild animals to get their meat and fish in rivers and streams. In this long process, people at that time evolved a super digestive system.

Type A blood appeared with the agricultural society, and it can be said that it was the earliest vegetarian engaged in agricultural production. At this time, food and livestock replaced the meat products obtained from hunting. Humans began to eat plant foods such as grains and vegetables, and at the same time formed a unique type A blood digestive system, which was more inclined to plant foods.

Type B blood is the third blood type, which is biased towards type O blood and different from type O blood. Grazing and domestication are deeply rooted in the B blood gene. For this kind of people, it is more suitable for a balanced diet and a little emphasis on meat.

Type AB blood appeared in human society at the latest. Anthropological research believes that AB blood is the offspring of Indo-Europeans with type A blood and Mongolians with type B blood, accounting for only 2%~5% in the world.
