According to the different antigens contained in red blood cells, ABO blood group system can be divided into four types: A type, B type, AB type and O type.
Blood type A contains only antigen A, blood type B contains only antigen B, blood type A contains both antigen A and antigen B, while blood type O contains neither antigen A nor antigen B. Everyone can only be one of these four blood types.
Rh blood group system can be divided into Rh positive blood group system and Rh negative blood group system. Rh positive blood type is the blood type owned by most people in our country, while Rh negative blood type is very few, which is called "panda blood".
The classification of blood type is detected by the principle of antigen-antibody reaction. People with different blood types have different antigens on the surface of erythrocyte membrane, which can agglutinate with corresponding antibodies.
The method of blood type detection is to take human peripheral blood, drop it on two slides respectively, and observe whether there is agglutination with naked eyes. If there is agglutination, it means positive. If a person's blood has anti-A serum reaction, it means that it is type A blood; If it reacts with anti-B serum, it means it is type B blood; If it reacts with anti-A serum and anti-B serum, it means that it is type B blood.
Medical staff will also make different judgments on different blood types according to the patient's situation when doing health checks, because different blood types will have different life physique and metabolic ability.
One of the husband and wife has type O blood. If the other person has these "blood types", the baby may be very lucky.
"O type blood +AB type blood"
Children born with AB blood and O blood are type A or B, because the gene for controlling blood type of people with AB blood is AB, and the gene for controlling blood type of people with O blood is ii.
According to Mendel's genetic law, it is known that the gene that controls the blood type of his children is Ai or Bi. Ai shows type A blood and Bi shows type B blood, so is the child's blood type A or B?
Because this child has the characteristics of type A and type B blood, his personality is complex and changeable, and his self-restraint ability is very strong. He treats his friends and family very warmly, giving people an elegant, quiet and soft impression, and never shows his emotions easily. No matter what happens, he can make a very calm judgment!
"type o blood+type o blood"
If both husband and wife are type O blood, then the child will definitely get the gene of type O blood.
People with type O blood will be docile when they are young, but they will show it when they grow up day by day.
At the same time, people of this blood type are also very enterprising, very sensitive to good and evil and very trustworthy.
However, people with this blood type are sensitive and alert, and they are tricky about some things, but they are more open-minded and open-minded emotionally.
"type o blood+type a blood"
Straight men with type O blood are informal and careless, and people with type A blood are meticulous and meticulous, which can make up for its shortcomings!
Children born with type A and O blood have a strong sense of purpose, boldness and enthusiasm, confidence in their own abilities, self-confidence, courage to challenge their lofty dreams, frank and optimistic personality, easy to become friends, leadership ability as a commander and full of sense of justice. After falling in love, they can give everything for each other without reservation.
"type o blood+type b blood"
The inheritance of blood type is regular. According to the blood type genetic table, we can calculate what blood type the child is. Children with type O blood and students with type B will only have type O or type B, and type O blood is more likely.
Children born with type O blood and type B blood have excellent analytical ability and judgment ability, are good at exploring the hidden laws behind things, can accurately analyze the essence of things, and establish rules according to the actual situation. If they are business leaders, they will quickly judge the market demand, so as to effectively realize their dreams!
Reading extension: how to give birth to a healthy baby?
give up drinking
Alcohol, the main component of wine, can cause chromosome aberration and gene mutation in human body. If you get pregnant after drinking, it will greatly affect the development of the fetus.
give up smoking
Doctors believe that if you smoke, it is imperative to quit smoking immediately, which is something you must do for yourself and your baby.
You may find it difficult to quit smoking, but if you still smoke during pregnancy, it will seriously damage the health of the fetus.
Stop losing weight
The woman should reserve enough nutrition before conception to ensure the healthy growth of the baby.
Although the fetus has the ability to continuously get nutrition from the mother regardless of the nutritional status of the mother, recent research shows that the lack of nutritional supply from the mother may reduce the final number of fetal brain cells and affect the future learning ability.
Stop taking oral contraceptives
Generally speaking, it is good to get pregnant after 6 months of stopping using contraceptives.
This is because the main component of oral contraceptives is hormones, which are several times stronger than natural sex hormones, and it takes a long time for the absorption and metabolism of oral contraceptives to be completely excreted after 6 months.
