Children born from blood type A and blood type B

What blood type will a child born from type A blood or type B blood have? This is a question that many parents want to know. There are many rules for the blood type of a child, and it is not certain what blood type the child will have. Some children are born with their mother's blood type, and some are born with their father's blood type. This is all genetic. Let's take a look at the following introduction to the specific blood type of a child.

There are many people with type A and type B blood. Many people want to know what blood type the children born from type A and type B blood will have. Everyone knows that the blood type of the parents can determine the blood type of the child. For this question, let's take a look at the detailed introduction in the past few days.

If the husband and wife's blood types are "A" and "B", the baby's blood type will be "O" or "AB" in addition to "A" or "B". Analysis: A, B, and O blood types are inherited according to the laws of Mendel's genetics. From the perspective of genetic genes, type A has two genes, AA and AO, type B has BB and BO, and types O and AB have one gene each, namely OO and AB. If both parents are type A and their genes are AA, their children can only be type A. If both parents have AO genes, their children's blood types may be A or O. If one parent is type A with AA genes and the other is AO, the child's blood type will be type A with AA or AO genes. The situation is exactly the same for Type B. If parents have blood type O and blood type AB, their children's genetic genes will be AO or BO, which means they can only have blood type A or B. If both parents are type O, their children will of course also be type O. When both parents are type AB, there are three possible blood types for their children: type A with gene AA, type B with gene BB, and type AB.

From the general public's perspective, there are four basic blood types: ABABO. The blood type of the parents determines the blood type of the child. The basic situation is as follows:

Possible blood types of children based on their parents' blood types

AxA A/O

AXB A/B/AB/O

AXAB A/B/AB

A/O

BхB B/O

BхO B/O

BхAB A/B/AB

ABхO A/B

ABхAB A/B/AB

Blood type refers to the different antigens contained on red blood cells. Red blood cells containing only A antigen are called type A, those containing B antigen are called type B, those containing both A and B antigens are called type AB, and those with neither A nor B antigens are called type O. ABO blood type is controlled by three ABO genes. The A gene controls the production of A antigen, the B gene controls the production of B antigen, and the O gene controls the non-production of A and B antigens. Genes exist in pairs. There are six different combinations of genes that control ABO blood type, namely AA, AO, BB, BO, AB, and OO, and each person has only one pair of them. ABO blood type genes are also divided into dominant and recessive. A gene and B gene are dominant, and O gene is recessive. For example, if a person's pair of genes is AA, then his blood type is A. If a person's pair of genes is AO, because the A gene is dominant and the O gene is recessive, the O gene cannot show its effect, and this person's blood type is also type A. The same is true for the B gene. If a pair of genes is AB, because both the A gene and the B gene are dominant, this person's blood type is type AB. Because the O gene is recessive, it must be expressed when a pair of genes are both O, then the blood type is O.

When blood type is passed on to offspring, the parents' reproductive cells (sperm and egg) each provide one of the pair of genes, reconstituting the pair of genes. If the father's blood type is A, the pair of genes that control the blood type are AO. When sperm is formed, the AO pair of genes separate from each other and enter two sperm respectively, becoming sperm with A gene and sperm with O gene. If the mother's blood type is B type, the pair of genes that control the blood type are BO. Similarly, when the egg is formed, an egg with a B gene and an egg with an O gene are formed. When fertilized, if the father's sperm with an A gene combines with the egg with a B gene, an AB type individual (fetus) will be formed, and the blood type is AB. If the sperm with an O gene fertilizes the egg with a B gene, an OB gene individual (fetus) will be formed, and the blood type is B. If the sperm with an O gene combines with the egg with an O gene, an OO gene individual will be formed, and the blood type is O.

Through the above introduction, we know that the blood types of children born to type A and type B blood are possible. Genes are really magical things. We must be able to understand our blood types in a timely manner. It is also important to know what blood type you have.
