What blood type will a child born from blood type O and blood type A have?

Many friends don’t know much about blood types, and some people don’t even know what their own blood type is. But generally speaking, everyone believes that what kind of blood type a mother has will determine what kind of blood type the child will have, and the general public believes that the child's blood type should be the same as the mother's. In fact, this understanding is wrong. So what blood type will a child born from type O blood and type A blood have?

In fact, the question of what blood type the child will have after a couple gets married is one of the questions that confuses many friends. Because if this issue is not clarified, it will cause huge misunderstandings for both the children and the entire family, and may even endanger family harmony. So what blood type would a child born from type O blood and type A blood have?

What blood type will a child born from blood type O and blood type A have?

What we usually call blood type is the blood type of red blood cells, which is determined based on the antigen specificity on the surface of red blood cells. It is known that there are 15 major blood type systems for human red blood cells, among which the main ones are A blood type, B blood type, O blood type system, and the second is the Rh blood type system (commonly known as the panda blood type).

There are two specific ways to determine a child's blood type:

One is obtained through professional medical blood typing, which is the most accurate method.

The other method is to derive it through the genetic laws of blood type, but this method can only determine the possible blood type of the child, and cannot clearly determine which blood type it is.

The determination of blood type is based on the presence of agglutinins in plasma (or serum). When agglutinogens and agglutinins of the same name meet (such as agglutinogen A and agglutinin B), red blood cell agglutination (hemolytic reaction) will occur. To judge.

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

Therefore: According to the inheritance law of human blood type: If the husband and wife's blood types are "O" type and "A" type, the blood types their children may have can only be "O" or "A" type. It is impossible to have blood types B and AB.

As for the question of what blood type a child born from type O blood and type A blood will have, the answer is already clear. In fact, through the regularity of blood types, we can see that when a couple with type 0 and type A blood types get together, the child born will generally take the blood type of the father or mother, that is, it may be type A or type O, but the blood types that will never appear are type B and type AB.
