What blood type does a person with AB and the other three blood types have a child?

There are three types of genes that determine a person's blood type.

A B and IA B are dominant genes, that is, if there is a or B, it will appear as blood type A or blood type B, and both AB are blood type AB.

I is a recessive gene, which will not be shown after A or B, and will still show blood type A or B, and if it is II, it will show blood type O.

Blood group is made up of one or two of these genes.

That is, it can be combined.

aa ab ai

bb biii

Six. All AA and AI are blood type A.

BB Bi is blood type B.

AB is blood type AB.

II is blood type O.

Then AB and A blood can give birth to 4 gene combinations of AA AI AB BI, that is, children with three blood types of A B AB can be born.

AB and B blood types can give birth to 4 gene combinations of BB AI AB BI, and can also give birth to children with three blood types of AB A and AB.

If two AB blood types are combined, three gene combinations of AA BB AB can be born, which is also a child of three blood types A B AB.

If it is combined with type O blood, the blood group genes of the child born may only be two types of ai bi.

With the exception of type O, all three are possible.

Many people are no strangers to blood type, but many people will be confused about what kind of blood type and what kind of blood type will be combined with what kind of blood type will give birth to a child. If you make a mistake about this issue, it may affect the harmony of the family. Next, I will teach you how to determine the blood type of a child according to the blood type of the parents.

Q: So what blood type will be born of AB blood type and the child born of AB blood type?

Usually what we call blood group, that is, the blood group of red blood cells, is determined based on the antigen specificity on the surface of red blood cells. Human red blood cells are known to have 15 major blood group systems, the main of which is the ABO blood group system, followed by the RH blood group system (commonly known as panda blood group).

A: There are two ways to determine your child's blood type:

One is that it is obtained by a professional medical shoe blood group test, which is the most accurate.

The other is to obtain it through the law of blood group inheritance, but this method can only determine the possible situation of the child's blood type, but cannot specifically and clearly determine which blood type it is.

Blood type is determined by the presence of lectins in plasma (or serum). When the eponymous agglutinator and agglutination meet (eg, agglutinin A and lectin B), erythrocyte agglutination (hemolytic reaction) occurs. to judge.

Therefore, in the blood of the human body, the types of lectins and lectins contained are different, so blood types can usually be divided into the following four types: blood type A, blood type B, blood type AB, and blood type O.

Therefore, according to the law of human blood type inheritance: if the husband and wife have blood types of "AB" and "AB", the blood type that the children may have is "AB", "A" or "B". It is unlikely that there will be a blood type "O".

Everyone has different blood types flowing in their bodies, and the blood types are inherited by their parents, what blood type the parents have, the child may be this blood type, so what is the blood type of the child born of blood type A and blood type B, in fact, all blood types are possible, let's go with it to find out.

Blood type is inherited through the cell chromosomes in the parents' body, usually the genotype of a person with blood type A can be AA or AI, then the person's germ cells have A or O, and the same is true for B gene, such as when a pair of genes is AB, because A gene and B gene are dominant, this person's blood type is AB type, because the O gene is recessive, it must be manifested when a pair of genes are O.

So after the combination of blood type A and blood type B, it is possible to give birth to a child with all blood types, and now everyone knows what blood type A and blood type B are born of children. Now the fifth blood group is found in the world, known as blood type C. This blood type is extremely rare, so it will be ignored here.

Children of father type A + mother type B are adventurers who are not afraid of failure, and they are happy by nature, no matter what setbacks they encounter, they will face them with a smile, so they may have a magnificent life, and the bold side makes up for the lack of flexibility unique to blood type A, making interpersonal relationships more extensive.

And you can make a lot of friends in life, even if you encounter greater difficulties, your friends will come to help you, and this is also related to what blood type A and B blood children are, and it will also be of great help to you in your career, as long as you continue to work hard, it is a very simple thing to succeed in your career.

What is the blood type of the child born of blood type O and blood type O, and the combination of the two is blood type O.

What is the blood type of the child born of blood type O and blood type B, and most likely blood type B.

Two people with AB blood typeLater, I learned that my brother was born with a child of blood type A, AB, and B.

Parental blood type: AB and AB, possible combinations: AB+AB, possible outcomes: AA, BB, AB, final blood type: A, B, AB.

In general, blood type is constant throughout life. Human blood types are generally divided into four types: A, B, O, and AB. Blood group inheritance is done with the help of chromosomes in cells.

There are a total of 23 pairs of chromosomes in a human cell, and each pair of chromosomes is made up of two single chromosomes, one from the father and the other from the mother.
