Couples The blood type of the child is different, the blood type of the couple and the blood type of

Possibly, the odds are low.

There are many reasons for changes in blood grouping.

1.Use of drugs that hinder the binding of antigens and antibodies, such as hormones, gamma (blocking antibodies), immunosuppressive drugs.

2.Genetic mutations, such as leukemia, can cause antigenic changes. (Extremely unlikely) 3machine or reagent error.

There is also the possibility that your husband is actually type B, the antigen is relatively weak, and the test mistakenly thinks that he is type B, and you happen to be heterozygous for type A, and your daughter has a 50% chance (your husband is a type B heterozygous) or a 25% chance of being type B (your husband is heterozygous for type B).

It is recommended that you have your blood type checked again.

I can't be sure, and I have to do a further paternity test if I want to figure it out.

The 8 percent is your child's mistake, 1 percent is your adoption, and the other 10 percent is your second marriage (there is a small one that may be very bloody, you can make up for it yourself). With the blood type of your two couples, your child's blood type should be one of these three types: type A, type O, and type AO, which is impossible to get rid of.

The blood group gene of the parent or parent.

There are 3 possibilities, one is that your 3 blood types are wrong, the second is that the child is not yours, and the third is that some of you have a very rare person whose blood type has changed, it is recommended to go to the hospital to recheck the blood type to avoid family disputes.

If the wife has blood type A and the husband has blood type O, there are only two possibilities for children, A or O, and each has a 50% chance.

If your blood type results aren't wrong, there's only one possibility:

You are the child's stepmother.

Because it is simply said that the father of blood type O has the possibility of having a child with blood type B.

If you're sure you're not getting your blood type wrong, then go for a paternity test, either because the child is holding the wrong child or if one of the couple's blood type is extremely rare. But the paternity test should be more accurate, and there will be no problems, and it is better to get things clear, otherwise your husband may become distrustful of you.

1 blood type is wrong, 2 individuals are mutated, 3 children are not biological, let's check again.

It means that this child is definitely not your husband's, but you and someone else's.

Almost impossible, unless genetically mutated. Do your research.

Really fake! If you're okay, you're holding the wrong child in the hospital!

This needs to be investigated.

Let's double-check.

No, go and check your blood type first.

If the blood type of the parents is A and B, the blood type of their children may be A, B, AB and O. If both parents have blood type A, then the child's blood type can only be type A and O. If the blood type of the parents is type B, then the blood type of the child can only be type B or O.

If the blood types of the parents are A and O, then the blood types of the children can only be A and O. If the blood type of the parents is AB and O, the blood type of the child can only be A and B.

Both husband and wife have blood type A, and the offspring can be type A or O. 2.One of the parties is type A and one side is type B, and the offspring can be type A or type B or type AB or O.

Expand the canopy cherry tree: one side is type A, one side is type AB, and the offspring can be type A or type B or type AB. One side of the two sides is type A and one side is type O, and the offspring can be hole-building or type O for type A.

Both sides are type B, and the offspring can be type B or O. One of the two parties is type B and one side is type AB, and the offspring can be type B or type AB or type A. One side of the two sides is chain plexus type B and one side is type O, and the offspring can be type B or O.

Both sides are AB type, and the offspring can be A or B or AB type. One of the two sides is type AB and one side is type O, and the offspring can be type A or type B.

The principle of ABO blood group identification is to divide blood groups into four types: A, B, AB and O according to the presence or absence of A antigen or B antigen on red blood cells. The red blood cell agglutination test can be used to accurately identify ABO blood group by positive (serum test) and reverse (cell test) stereotype.

Blood Group Paternity Test Form.

The so-called positive stereotype is to use the serum of known anti-A and anti-B types to determine whether there is a antigen or B antigen on red blood cells, and the so-called anti-type is to use known A cells and B cells to determine whether there is a corresponding anti-A or anti-B in the serum.

Couples with the same blood type have different contents in each couple, but on average, such couples are more stable and less prone to breakup.

From the perspective of the relationship between men and women, although the same blood type does not produce strong attraction like auxiliary relationships, it is easy to have heart-to-heart feelings. This affection is manifested in the fact that when both men and women work together or talk about the same topics, they often have the same ideas and consistent opinions, and with it, a like-minded relationship arises.

Generally speaking, this kind of family lacks a sweet atmosphere, and the relationship between the two is relatively weak, and they lack the strength of each other. Despite this, such couples are very stable in their long-term lives and rarely break up.

Although these types of husband and wife relationships are emotionally weak, they are easy to agree on topics and ideas to talk about together. Rather than being a loving couple, they are a couple moving forward side by side.

No, fetal or neonatal hemolytic disease generally does not occur if both spouses have the same blood type. Pregnancy is a process that lasts more than 9 months, and the fetus will be affected by a variety of factors in this process, so pregnancy has a certain risk, and various abnormalities can be found in time through regular prenatal checkups.

1. If the mother is blood type 0 and the father is a blood type other than type 0, the fetus is prone to cave blood disease, but the hemolysis caused by ABO blood group incompatibility is generally mild and will not be very serious.

2. Fetal cerebral palsy is generally caused by hypoxia during pregnancy or childbirth, so paying attention to pregnancy health care and prenatal examination can effectively prevent and detect early.

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.

The main component of chromosomes is deoxyribonucleic acid, which is commonly referred to as DNA, which determines inherited traits and function.

DNA can be divided into many segments, each of which has a specific inherited trait and function, and these segments are called genes. A small fragment of DNA in the same position on two single chromosomes in a pair of chromosomes, called an allele.

The locus of the ABO blood group system is on chromosome 9. Human ABO blood group is controlled by three genes: A, B, and O;

However, there are only two ABO system genes on the 9th pair of chromosomes in each human cell, namely a pair of alleles in AO, AA, BO, BB, AB, OO, where the A and B genes are dominant genes and the O gene is recessive genes.

Blood type is determined by the combination of three genetic factors such as A, B, and O, and most of them can be judged according to the blood type of the parents. As shown below:

Blood group is a classification based on differences in antigens of the same family on the surface of human red blood cells. Because human red blood cells contain different agglutinogens, the blood is divided into several types, so it is called blood type.

According to Mendel's law of gene segregation, the law of free combination, and the codominance of blood groups, the genotype of blood with phenotype A may be IAIA and IAII, and the phenotype of IAIA and IAII after separation produces IA and IA, and the phenotype of IAII producing IA and IA is determined with IA or IB. If the genotype is both IA or IB, it is blood type A or blood type B, both are AB type, none of them, and the genotype is III and the phenotype is O.

It may be type A, or it may be type O, but generally the surface of type A is large, hehe.

A, B, O blood types are inherited according to the law of Mendelian genetics, A, B, O, AB four blood types from the genetic point of view, A type has AA and AO two genes, B type is BB and BO, O type and AB type each is one, that is, OO and AB. When both parents are type A and both genes are AA, the child can only be type A. If both parents have Ao genes, the blood type of their children can be A and O.

If one parent is a parent with a gene AA and the other parent is a type A parent with AO, the child's blood type is either a gene AA or a parent with AO. The occasion of Type B is exactly the same. For parents with type O and AB, the child has a genetic identity of AO or BO, i.e. it can only be a blood type A or B.

When both parents are type O, and of course the children are also type O, and when both parents are blood type AB, there are three possible blood types of children: type A with the gene AA, type B with BB, and type AB.

It must be type A, otherwise it's not normal.

Parent's blood type--- child's blood type a, a, o

a＋b a、b、o、ab

a＋o a、o

a＋ab a、b、ab

b＋b b、o

b＋o b、o

b＋ab b、a、ab

o＋o oo＋ab a、b

ab＋ab a、b、ab

In addition, there may be other possibilities, but the probability of such a gene mutation is too low to occur, so we usually determine the blood type of the offspring from the above arrangement;

In fact, there is no absolute answer, only a relative answer, and a sentence of genetic variation will veto the previous answer.
