O What blood type does AB blood group combine with offspring?

According to the law of blood group inheritance, if the husband and wife have blood types of "O" and "AB", the blood type of the baby can only be "A" or "B", and there will be no "O" or "AB" type.

1. Genotype of blood type A: IAI or IAIA;

2. Genotype of blood type B: IBIB or IBI;

3. Genotype of AB blood type: IAIB;

4. Genotype of blood type O: II.

Genotype is a general term for all the genetic combinations of an individual in an organism. It reflects the genetic makeup of an organism, i.e., the sum of all genes obtained from both parents.

Introduction to the classification of the blood group system:

1. ABO blood group system: the blood type system divided by a and B on the surface of red blood cells with or without specific dust filial piety antigen (agglutinogen). ABO blood group distribution is regional, ethnicity-related. The inheritance of the ABO blood group system is determined by a single gene.

2. Rh blood group system: Another major feature in blood is rhesus factor, rhesus factor (rhesus blood group system) is also read as rh antigen, rh factor, because it is the same antigen as rhesus monkey red blood cells.

In the Rh blood group system, Rh is controlled by genes with two alleles on the first pair of chromosomes. Rh+ is dominant, and Rh- is recessive.

There are only two possible offspring of blood type A and type O. There are two cases:

1. If the father's genotype is IAIA and the mother is blood type O, the offspring's genotype must be type II, 100% of the blood type is type A, and the genotype is type IAI;

2. If the paternal genotype is IAI, then 50% of the offspring may have blood type A and 50% may have blood type O.

In summary, when the paternal genotype is the probability of the above two conditions, respectively, the probability of offspring blood type A is 75%, and the probability of type O blood is 25%.

<> blood types A, B, O are inherited according to the law of Mendelian genetics, A, B, O, AB four blood types from the genetic point of view, type A has two genes, AA and AO, type B 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.

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. The genetic law of blood group is: a+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→o; o+ab →a、b; ab+ab→a、b、ab。

Type O people have strong self-confidence and never regret once they have made up their minds. This characteristic also leads to the stubbornness of Type O people, their stubborn temperament and their inability to evaluate others correctly, their inability to get along with those around them, and their lack of humility due to overconfidence. In addition, Type O people are mainly rational and rarely dominated by emotions, and as a result, they have a calm attitude towards people and things, and are prone to become cold, gradually moving towards extreme individualism.

Generally speaking, Type O people are strong-willed, hardworking, and dominant. This is the result of the contradictory effect of the inferiority complex and strong self-affirmation requirements of Type O people. Type O people also have an inferiority complex and deliberately adopt a strong posture in order to hide or overcome their inferiority complex.

Long-term bluffing and pretending to be powerful can certainly get rid of the inferiority complex, however, this practice causes a heavy burden on Type O people, and some Type O people who can't bear the pressure psychologically turn to one"Imbeciles"The image appears, playing the role of a jovial clown in life.

In the face of social contradictions, spiritual entanglements, friction with others and difficulties at work, Type O people are extremely bad at solving them through psychological paralysis and compromise with themselves, but try their best to hide their troubles, work secretly, keep silent, and hide secrets in their hearts.

<>1) The inheritance of blood type comes from the parents, and the following describes the blood types of the children born to the parents according to their respective blood types: type and type A - type A and type O; Type and Type B - Type A, Type B, Type O, Type AB; type and type AB - type A, type B, type AB; type and type O - type A, type O; type and type A - type A, B, O, AB; type and type B - type B, type O; type and type AB - type A, type B, type AB; type and type O - type B, type O; type and type A - type O, type A; type and type B - type O, type B; type and AB type - type A, type B; type and type o - type O; type and type A - type A, B, AB; Type and Type B – Type A, Type B, Type AB; type and type AB - type A, type B, type AB; type and type O - type A, type B; Type and other types - type A, type B and not type O. 2) This is generally the case, but there are two exceptions:

1.O-type of the Mumbai type; 2.Genetic mutations.

In the genes, IA and IB are dominant factors, and I is a recessive factor, so there is a situation where the genetic and blood group manifestations are not necessarily the same. For example, a person with an IAIA or IAI gene has a blood type A in the form of a blood type; People with the IBIB or IBI gene have a blood type B; Only people with the II gene exhibit type O; People with the IAIB gene present with type AB. (There are two combinations of genes for types A and B, while there is only one combination for types AB and O.)

From this, it is not difficult to deduce from the blood type of the parents that the blood type of the child may and may not appear. (Note: The blood type of the children can only be inferred from the blood type of the parents, why?)

For example, if the parent's blood type is A and B, there can be 4 blood types A, B, AB, and O, but this is only relative, and if these four blood types can appear, the parent's genotype can only be produced if it is IAI and IBI!

The Ab type, which is more rational than rational, is good at analysis and criticism, and this characteristic makes the interests of the AB type person colorful. Because AB people are good at analyzing things from different angles, AB people can find their interests in a large number of things, especially in anthropology, archaeology, psychology, ecology, biology and other things that are closely related to human beings or human trends. Because of the wide range of interests, the interests of Type AB people tend to be less persistent.

Therefore, it is often considered that it is a lack of perseverance and cannot do anything for long.

The temperament characteristics of Type AB people have both the characteristics of Type A and Type B people. Type AB people tend to be Type A people in terms of social life, and tend to be Type B people in terms of personal life, and in terms of social life, Type AB people appear to be emotionally stable, calm and composed; In terms of personal life, Type AB people show emotional capriciousness, but unlike Type B people's emotional changeability, Type AB people's emotional changeability often manifests itself as sudden emotional disorders, and interests and hobbies can be expressed in actions as if no one is around.

Answer]: The EABO blood group system is controlled by genes from 3 isolated loci, and the genes from the chromosomes of both parents can be composed of 6 genotypes (OO, AA, AO, BB, BO, AB); The law of co-occurrence inheritance is followed when the legacy is passed on, and four phenotypes of A, B, O, and AB are formed in the children or generations, that is, blood groups (A, B, O, AB).

Type A or O, because the genotype of blood type A may be IAIA or IAI, and the genotype of blood type O is II.

As you asked.

The blood type A and O that the children of the marriage match may have.

It is impossible for children to have blood types B and AB.
