o The parents of people who practice blood are generally what kind of blood

Generally speaking, the genetic composition of ABO blood group is: ("I" is used below to represent recessive genes) Type A: AA, AI

Type B: BB, BI

Type O: Type IIAB: AB

The blood type of two people's children is half of the genes in the blood type of the parents, such as type A and type A people: first of all, both parents are type A, but it may be AA or AI, each with a 1 2 chance. But the result of the final combination may be AA, AI, or II, that is, the child may be type A or type O.

The same is true for people with type B and type B: the child should be type B or O.

Type O and Type O people: The child can only be Type O.

AB and AB type: It may be A, B or AB, but it can never be O.

People with types A and B: All blood types are possible for children.

Type A and Type O: The child may be Type A or O.

Type A and AB people: may be type A, B or AB, never type O.

Type B and Type O: The child may be Type B or O.

Type B and AB people: may be type A, B or AB, never type O.

Type AB and O: The child may have type A or B.

So, just figure out the intrinsic genotype of each blood type:

Type A: AA, AI

Type B: BB, BI

Type O: Type IIAB: AB

Then make a combination and you're good to go.

We hope you are satisfied!

The blood types of the parents will generally be O and O, A and O, A and A, A and B, B and O, B and B

Parents who don't have type AB are all possible.

All are possible except for type AB.

It's not just the parents who have O-shaped blood, but the offspring who have O-shaped blood. As long as neither of the parents is abstinent, it is possible that the offspring will be o-blooded. It's a genetic problem, just look at the biology books.

Yes. A and B, A and O, B and O, O and O

Children are likely to be Type O.

There are four types of human blood types, A, B, AB, and O. Among them, the genes of blood type A are AA and AI, the genes of type B are BB and BI, the genes of type AB are A and B, and the genes of type O D are II. As long as both genes contain I, then after the combination, the child may have type O blood.

Not really. A, B, and O are all possible, but they can't be type AB.

Only blood type O will occur.

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.

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, but 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 genes A and B are dominant genes and O genes are recessive genes.

Must o, o blood type is a recessive gene in biological inheritance, only on the chromosome both DNA are recessive, can it be revealed. So, theoretically, if you go out with a genetic mutation, the child is also O

Hello: According to the law of blood group heredity:

Both parents have blood type O, and the child may have blood type O. The blood types that cannot be had are A, B, and AB.

Just look at the table of blood group hereditary patterns and it will be clear:

The genes that control blood type are A, B, and O.

Genotypes exhibiting blood type A: AA, AO

Genotypes showing blood type B: BB, BO

Genotype exhibiting AB blood type: AB

Genotype exhibiting blood type O: OO

Therefore, both parents are blood type O, and the child must be blood type O, of course, except for special circumstances such as other variants.

O-type

The blood type of the parents The blood type that the child may have The blood type that the child may have.

It doesn't have to be type O, as it is possible that it was picked up.

Is the blood group genetic chart 100% accurate?

O to O, A to O, A to A, A to B, B to O, B to B.

Introduction to blood grouping: Blood group is a classification based on the difference 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.

There are many types of human blood types, and each blood group system is determined by genetic factors and has immunological properties. The most common blood group system is ABO blood group, which is divided into four types: A, B, AB, and O. followed by the Rh blood group system, which is mainly divided into Rh-positive and Rh-negative; The second is the MN and MNS blood group system. According to the current clinical testing at home and abroad, more than 30 human blood types have been found.

If the child has blood type O, the blood type of the parents will be: O and O, A and O, A and A, A and B, B and O, B and B.

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.

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

7. B and B: The blood type, B, and O that the child will appear

8. B and AB: The blood type, A, and B that the child will have

9. AB and O: The blood type, A, and B that the child will appear

10. AB and AB: the blood type, A, B, AB that the child will appear

Father type O, mother type O, ***** child type O.

Father type A, mother type A***** child type A or O.

Father type B, mother type B***** child type B or O.

Father type A, mother type O***** child type A or O.

Father O, mother A***** child A or O.

Father type B, mother type O***** child type B or O.

Father type O, mother type B***** child type B or O.

Father A, mother type B***** children A, B, O, AB are all likely to be father B, mother A***** children A, B, O, AB are all father AB, mother O***** children A or B.

Father type 0, mother AB type***** child type A or B.

Father type AB, mother type A***** child type A or AB type Father type A, mother type AB***** child type A or AB type Father AB type, mother type B***** children type B or AB type father type B, mother type AB***** children type B or AB type Father AB type, mother AB type***** children A or B type or AB type above are the matching types of A, B, and O blood types, right.

The 1st floor and the 2nd floor are wrong.

Neither parent can be AB-type!!

Khan, comrades who don't understand, don't mislead the landlord.

Nala Lala Cheerleader This one is right The blood type of the parents can only exclude AB type, and any other blood type is possible.

Children with blood type O.

Genes can be expressed as II

then both parents have an i gene.

Only type A and type B and type O are possible.

It can't be type AB.

Parents are all possible except for AB

Neither parent is type AB.

a, b, o are all possible.

It's one of the few O-shapes that is 100% O-shaped.

Haha, why do you ask this question?

We all know that, in general, there are four types of blood in people: type A, type B, type AB.

Type O. There are three i(a), i(b) and i that determine human genes, and each person is composed of two genes, i(a) and i(b) are dominant to i, so the blood type of human beings is like this: type a [i(a)i(a)], type a [i(a)i], type b [i(b)i(b)], type b [i(b)i], type b [i(b)i], type ab, type o [ii], to be strict, there are 6 blood types, only when the blood type of the parents is type a and b, It is possible to give birth to 4 completely different blood types A.

Type B, AB and O.

The analysis shows you, you o

You love O, pair in pairs, no matter how you give birth, your children are O-shaped.

Hello: According to the law of blood group heredity:

Both parents have blood type O, and the child may have blood type O. The blood types that cannot be had are A, B, and AB.

Just look at the table of blood group hereditary patterns and it will be clear:

Parents are type A and B, and children are A, B, AB, O;

Parents are type A and AB, and children are A, B, AB;

Parents are type A and O, and children are A, O;

Parents are type A and A, and children are A, O;

Parents are type B and B, and children are b, O;

The parents are type B and AB, and the child is B, A, AB;

Parents are type B and O, and children are B and O;

The parents are type AB and type AB, and the child is A, B, AB;

Parents are type AB and O, and children are A, B;

The parents are type O and O, and the child is type O.

In addition, there are special circumstances that can not follow the above rules. This blood type is a case where the blood type is O, but the genotype is not O. This O-type is:"Bombay type"O-type.

Because they do not have the gene to produce the precursor material of the A or B antigen, they still behave as type O despite having the A or B gene. There is also the case of a genetic mutation. Both of these conditions are particularly rare.

Whether you give birth to a daughter or a son, it should be O-shaped.

99 percent are blood type O, but it is possible to have something else.

The vast majority of cases are blood type O.

Only blood type O can not be anything else.

It can only be type O, if it is other types, Congratulations to the landlord, grab the green hat.

The above few, mom is not necessarily just type O, hehe. Let's take a look at the relationship between the blood type of the parents and the children (only the parents contain type B and the children contain type O): The blood type of the parents --- the blood type of the children A+B---AB, A, B, O B+B---B, O O+B---B, O Through the above, it can be determined that the mother may be type A, B, O, and the father is type B, and it can be seen from the above that the son's blood type may be AB, A, B, O.

Still don't get it? Then another mother may be all possible, and what about the son, all are possible. We biology just learned this.

To put it simply, human genes are made up of half of each parent, so human chromosomes will be paired, and because the number of chromosomes is the same for both men and women. Human blood type is controlled by two genes, each in the same position of the same chromosome of the parents, this gene has three kinds, ia, ib and io, of which a and b are dominant, o is recessive, that is to say, if a or b exists, o characteristics will be masked, only when the above two genes do not exist, o gene will reflect the trait, that is, the blood is o type. There is no precedence between AB, so AB blood type occurs when they are present at the same time.

That is to say, if it is IAIA or IAIO, then the guy is type A, if his gene is IBIB or IBIO, then it is type B, and so on IAIB is type AB and IOIO is type O. In the process of inheritance from parents to children, the two pairs of genes given to them by their grandparents should be separated and the remaining half should be combined, and the other party should be combined to give a pair to the child. Therefore, the father is type B, it can be IBIB or IBIO, and the mother, whether it is type A IAIO, type B IBIO, or type O IOIO, may give birth to type O daughters, by the way, I forgot to say that blood type has nothing to do with gender.

Then you split the father's possibilities and the mother's possibilities into singles, and then pair them up one by one, and see for yourself how many possibilities there are.

So: a, b, o are all possible.

a。Each human has a variant chromosome.

Biologically speaking. The mother is blood type O

Blood group genetic relationship.

There are many different types of blood in humans, and they are very complex. What we usually call red blood cell blood groups: A, B, O and AB, actually belong to a blood group system, called ABO blood group system.

Twenty-six blood group systems have been found in humans, each with a varying number of blood groups. However, among these blood group systems, the ABO blood group system was the earliest and most relevant to humans.

There is a genetic basis for blood type. Half of a person's blood type comes from the mother and half from the father. For example, if the mother passes on the B factor to the offspring and the father passes on the O factor, the offspring's blood type is Bo, and because O is recessive, only B type is exhibited.

According to the law of blood group inheritance, the blood type of the parents is known. It can be deduced that the child may or may not be of that blood type, which can provide some reference value in the forensic evaluation of parental authority. If you're interested, find out what your child's blood type is.

Please see the table of genetic relationships of blood groups).
