What blood type is the child born to a husband and wife with type B and type A 20

This situation is complicated, if it is IBIB IAIA, the child's blood type is AB; In the case of IBI IAIA, the child's blood type may be AB or A; iBI IAI, blood type can be AB, A, B, O; ibib×iai；The blood type is AB or B. All in all, this is the most complex combination, which can encompass almost all blood types of ABO...

Type A, Type B, Type AB, Type O, are all possible, and the probability of each blood type is 25%.

It is possible to have a child with all four blood types A, B, AB, O.

The blood type of the parents and the possible blood type of the children.

Parent's blood type Children may have blood types.

o ＋ o o ＋ a o ＋ b o ＋ abo o、a o、b a、b

a ＋ a a ＋ b a ＋ ab

o、a o、a、b、ab a、b、ab

b ＋ b b ＋ ab

o、b a、b、ab

ab ＋ ab

a、b、ab

Type A, Type B, Type AB, and Type O are all possible!

It could be A, it could be B, it could be AB. Check it out for details.

Children may have types A, B, and AB.

Type A, Type B, Type AB, and Type O are all possible.

Husband's blood type O, wife's blood type A, biological baby's blood type B.

What is the blood type of the child born of type A and type B, I don't know much about the blood type, and many parents will joke to make fun of the child, in order to solve the child's doubts, we will explain what blood type is the child born to Sun Kai type A and let Gao Bei type B.

1.First of all, the blood type of the child is a new blood type formed by mixing part of the father's blood group (a, b or o) and part of the mother's blood group (a, b or o), and this new blood type is the blood type of the child, so the blood type of the child is related to the blood type of the parents.

2.Secondly, the ABO blood group is mainly determined by the lectins and agglutines contained in the blood, and several blood types in the blood group ABO blood group of children born with blood type A and blood type B are possible, that is, type A, B, AB and O are all possible.

3.Finally, according to the law of human blood type heredity, the children born by the combination of type A and type B may be O, A, B, AB any blood type, and it is really not safe to do a paternity test.

Precautions. What is the blood type of the child born of type A and type B, there will be no more misunderstandings after understanding, and parents should not joke about these, which will make children have shadows. If you really have doubts, you can do the identification of the pro-tan destroyer, and the accuracy will be relatively high.

Summary. Abnormal. It is not normal for both husband and wife to have type A blood, and it is not normal for the child to be born with type AB.

If both husband and wife have blood type A, genetically speaking, it is impossible to give birth to a child with blood type A and blood type O, and it is impossible to give birth to blood type AB. Therefore, you should carefully check whether the blood of both husband and wife is tested accurately.

Both husband and wife have blood type A, and the child born is type AB, is it normal?

Hello, I am helping you to inquire about the relevant case and will reply to you immediately.

Both husband and wife have blood type A, and the child born is type AB, is it normal?

Abnormal. It is not normal for both husband and wife to have type A blood in their limbs, and it is not normal for the child to be born with type AB. If both husband and wife are blood type A split states, genetically speaking, it is impossible to give birth to a child with blood type A and blood type O.

Therefore, you should carefully check whether the blood of both husband and wife is tested accurately.

Children born to couples with blood type B and blood type B will have type B or O.

According to the table of genetic laws of blood group, the details are as follows:

1. O and O: The blood type and O that the child will appear

2. A and O: The blood type, A, and O that the child will have

3. A and A: The blood type, A, and O that the child will have

4. A and B, the blood type that the child will appear, A, B, Ab, O5, A and AB: the blood type that the child will appear, A, B, Ab6, B and O: the blood type that the child will appear, B, O

It is possible that the blood type of the child born to the husband and the wife with blood type B is A, B, AB and O.

Normally, blood type is constant throughout life, and blood type is inherited with the help of chromosomes in cells. Human cells have a total of 23 pairs of chromosomes, each of which is made up of two single chromosomes, one from the father and the other from the mother.

The main component of chromosomes is the DNA that determines the inherited traits and functions, that is, each segment has a unique genetic trait and function, and these segments are called genes. The gene locus of the ABO blood group system is on the 9th pair of chromosomes, and the ABO blood group is controlled by three genes: A, B, and O, which can be combined into six pairs of alleles: AA, AO, BB, BO, AB, and OO.

In the ABO blood group system, genes A and B are dominant, while gene O is recessive. In this case, both parents are dominant, so it is possible to have a child with type A, type B, type AB, and type O.
