My husband and I both have type O blood, why is the child type B?

Check yourself and your husband first, and ask your doctor for advice or the advice of a relevant specialist.

It's big or small! ......

Let's do a paternity test.

I don't think it's your own children.

No one can change the laws of heredity, unless there is a genetic mutation, and it is not known how likely the mutation is.

Could it be when you just gave birth?

The hospital made the child mistaken.

In medicine, don't say it's impossible. Blood type is not as simple as imagination, and Mendelian laws of inheritance are not universal truths. You will definitely say that it is impossible for O-type and AB-type parents to give birth to O-type and AB-type offspring, but this has been reported in the literature and news.

In the same way, it is advisable to do a paternity test and do not jump to conclusions before the results are available.

In addition, if the H gene is deficient in the human body, it will cause the A and B antigens to be unable to be produced, even if the genotype has A or B, it will also show a negative A antigen and B antigen, that is, it will be considered O type, and this O type is called OH type.

Adults are all blood type O, and children must be type O. There's no doubt about that.

1: You two are testing it to see if it's right.

2: If that's right, the kid is definitely not his own.

3: If it must have been born by himself, the father of the child is very suspicious.

There is no need to do any DNA identification for this, and the blood type can be completely identified.

I am very scientific about the above, and I hope the landlord can forgive me for the offense!

Can anyone explain? I can only explain partially. Not mine.

I'm also type O.

Oh, my God!! There is such a thing in the world??

No gangsters.

I'm sorry, I don't think it's your own children. No one can change the law of heredity, unless there is a genetic mutation, I don't know what the probability of mutation is, ask the doctor. Try to change a few more hospitals, for a clean value.

It's better to check again, if it's not an error, then the reason for this has to ask lz himself

It is best for both husband and wife to check the blood type again, and if it is true that both parties are type O and the child is type B, DNA testing can be done.

It can only be type O, for the sake of prudence, the three of them will go to the hospital to check the blood type together, if it is still as you said, then it is only to do a paternity test.

Theoretically, this is not possible, but it is also possible that there is a genetic mutation, so agree with the opinion of the upstairs and go to the hospital for a check-up.

It's best to double-check again, and if that's right, ask yourself.

Identify the blood type of 3 people, if it is correct, then think about it yourself!!

It's very doubtful.

The first floor is done correctly, hehe.

Another: If the H gene is deficient in the human body, it will lead to A, B resistance.

Eh, I hugged the wrong child, it's troublesome

O+O can only be O, it's 100% of the thing. Who is the father of the child?

Type B or O.

Blood type is the outward manifestation of inherited genes. Because the genes that determine the type of mindful blood that determine renting are a dominant set of genes, the same blood type may correspond to multiple gene types.

For example, blood type A may correspond to two gene types, AA, and AO; Similarly, blood type B also corresponds to two gene types, namely BB, and blood type and AB blood type only correspond to one gene type, which are OO and AB.

In summary, the combination of blood type O and blood type B can obtain Bo and Oo gene types, that is, type B or O.

Therefore, the child's blood deficiency type is either O or B.

At present, there are 35 human blood group systems discovered, the common ones are A, B, AB, O blood, and the commonly heard is Rh-positive negative blood, but there is no Q blood. If the subject is type O, the husband is type B, and the daughter is type A, then there is a problem.

The blood group system commonly used in daily examinations is the ABO blood group system, which is mainly based on the glycoprotein on the surface of blood cells. The structure of glycoproteins is different, and the antigenic properties are different, resulting in some differences in the presence of cells. Blood cells type A have A antigen and A antibody in serum, blood type B has B antigen in blood and B antibody in serum, and A and B are both dominantly inherited, similar to Ai and Bi blood types, which are also blood types A and B, and I is equivalent to recessive inheritance;

Red blood cells of type O do not have A antigen and B antigen, serum plasma contains anti-A and anti-B antibodies, and type O blood can be expressed as II, which is recessive, and only homozygous can manifest as type O blood. There are two pairs of type O and B blood: II and BB, II and BI, according to the law of heredity, the result can only be BI or II, that is, blood type B or blood type O, and the ratio of blood type B to blood type O in a child is 3:

1. It is impossible to have blood types A and AB.

So if the subject is type O, her husband is type B, and the child is type A, then there is a problem. There are probably only a few exceptions: holding the wrong child, but the possibility is very small, modern is different from the past, every child will be born with a bracelet or ankle ring, a delivery room only accepts one mother at the same time, the probability of error is very low; In view of the error of blood group test, in view of the fact that a blood report is a report, and the modern test strip is becoming more and more sensitive and accurate, and there may be a need for blood transfusion in the hospital, the wrong blood type is likely to kill people, this possibility is extremely low, and there are very few cases of wrong blood transfusion in the country every year because of the wrong blood type test; However, although the first two possibilities are very small, they cannot completely negate the possibility.

In the end, something happened that was not humane, and only the person concerned knew best.

There's also a very, very faint possibility, and that's a new blood group system. Human blood type is not stable, some studies have shown that blood type A and B are born from blood type O, so it is possible to mutate to produce a new blood type in addition to the known blood type of humans, just like the known 35 blood types, not all exist at the beginning, but the combination with type B still cannot give birth to a child with blood type A.

I'm 0 and my husband is B. We are both boys. It's not like hemolysis as people say. Their hospital just said that type 0 people have a better chance of getting hemolytic disease than other blood types.
