O and blood A, O blood type can produce blood type

Blood type O can be produced from types A and A, A and B, A and O, B and B, B and O, and O and O.

Scientific research has found that there are three genes that control the ABO blood group in humans: IA, IB, and I. Among them, IA and IB are dominant to I, and there is no explicit implicit relationship between IA and IB.

That is: the genetic makeup of blood type A can be IAIA or IAI; The genetic makeup of blood type B can be IBIB or IBI; The genetic makeup of AB blood is IAIB; The genetic makeup of type O blood is II.

Usually with only two antiserum, anti-A and anti-B, the population can be divided into four blood groups.

O and O, A and O, A and O, A and B, B and O, B and B can give birth to blood type O. 、

Blood type O is a blood type that does not contain either A antigen or B antigen on the surface of red blood cells, and is commonly known as a "universal blood transfusion". However, because it burns in the plasma and contains anti-A and anti-B antibodies, the tremor may cause varying degrees of hemolysis of red blood cells in the recipient.

Blood types can also be divided into Rh-negative and Rh-positive, Rh-positive type O, which cannot be transfused to Rh-negative type O, and Rh-negative type O, which can be transfused to Rh-positive type O in small amounts, including Rh-positive type A, type B, and AB type. The total number of RH negative cases in our country will not exceed three per thousand, on average.

Blood type A and blood type O, and the ratio of blood type A to blood type O is 3:1, and blood type B and blood type AB are not likely.

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 blood type of both parents can be passed on to their children, and it is carried out according to certain principles of inheritance.

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, and OO, in which A and B genes are dominant genes and O genes are recessive genes.

The genetic pattern of blood group** is as follows:

OK.

According to the genetic pattern of blood type, and for the sake of clinical practice, the blood types of children born to spouses are as followsMatchmakingThe blood type the child may haveA blood type that a child cannot have

a×aa、ob、ab

a×ba、b、o、abNone

The parents are of blood type A and B, and the child can be of any of the blood types A, B, O, and AB. Absolutely! Scientifically Proven:

Type A and B Type A, B, AB, O B Type and B Type B, O A, AB A and A Type A, O B, AB O Type and O Type O A, B, AB A and O Type A, O B, AB B and O Type B, O A, AB A, AB

This is quite normal. From the perspective of genetics, blood type inheritance belongs to autosomal recessive inheritance, and parents of blood type A and blood type B can give birth to children with four blood types: blood type A, blood type B, blood type O, and blood type AB. Don't be surprised or worried.

Yes, the combination of A and B may give birth to four blood types A, B, AB, O, blood groups A and B are dominant genes, and O is a recessive gene, as long as there is a A in it, it will indicate blood type A. b In the same way, it is possible to have type O when two children born with a recessive blood type are born

Many people are no strangers to blood type, but many people will be confused about what kind of blood type and what kind of blood type will be combined with what kind of blood type will give birth to a child. If you make a mistake about this issue, it may affect the harmony of the family. Next, I will teach you how to determine the blood type of a child according to the blood type of the parents.

Q: So what blood type will be born of blood type O and blood type A?

Usually the blood group we refer to as the blood group of red blood cells, which is determined based on the specificity of the antigen on the surface of the red blood cells. It is known that there are 15 major blood group systems in human red blood cells, the main of which are blood group A, blood group B, blood group O system, and followed by the Rh blood group system (commonly known as panda blood group).

A: There are two ways to determine your child's blood type:

One is that it is obtained by a professional medical shoe blood group test, which is the most accurate.

The other is to obtain it through the law of blood group inheritance, but this method can only determine the possible situation of the child's blood type, but cannot specifically and clearly determine which blood type it is.

Blood type is determined by the presence of lectins in plasma (or serum). When the eponymous agglutinator and agglutination meet (e.g., agglutinin A and lectin B), red blood cell agglutination (hemolytic reaction) occurs. to judge.

Therefore, in the blood of the human body, the types of agglutina and agglutinate are different, so blood types can usually be divided into the following four types: A, B, AB, O blood types.

Therefore, according to the law of human blood type inheritance: if the husband and wife have blood types "O" and "A", the children may have only "O" or "A" blood types. It is unlikely that there will be blood types B and AB.

According to the law of blood group inheritance, type O blood and type O blood cannot give birth to type A blood. Blood type O and blood type O can only produce blood type O, and no other blood types can occur.

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.

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.

Genetic law of blood type: 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→ab、ab。

There are o ten o a, but very rarely, there is a couple who are 0 but the child is a, and the DNA is biological.

Blood type inheritance comes from parents, and I will give you a brief introduction to the blood types of the children born to the parents according to their respective blood types:

type and type O - type A, 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 A - 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.
