There are cases when, after the birth of a child, young parents, having learned his blood type, experience conflicting feelings, thinking that their child has been changed - after all, neither the father nor the mother has the same blood type as the child.
Really nothing to worry about, just be aware of what blood types a child can inherit from their parents.
Often, parents are interested in the question of how to find out the blood type of a child (possible combinations). It turns out that today you can do this by knowing the parental blood types.
Let's try to figure it out. First, let's look at the history of the discovery of blood groups. This event took place at the beginning of the twentieth century. Austrian Karl Landsteiner drew attention to the fact that when mixing the blood of several people, red blood cells can behave differently: in one case they stick together, and in the other there is no such reaction. This led the scientist to the idea that there iscompatible and incompatible blood types. This discovery was of great importance, because thanks to the knowledge of the compatibility of certain groups, it became possible to safely transfuse it.
Two decades later, scientists also learned about the inheritance of groups from parents, which occurs in accordance with the laws of genetics discovered by G. Mendel. Like any sign of heredity, the blood type is determined in accordance with the fact that one gene from a pair is transmitted from the parents. Thus, parents do not pass on a ready-made group, but only one gene, on the basis of which the baby’s blood group is formed, which does not always coincide with the parent.
There are several different classifications of blood types, but the most common is the AB0 system, which includes 4 blood types.
How to find out the blood type of a child based on the blood types of the parents? It's simple, you need to refer to the law of inheritance of genetic traits.
1 group, it is also zero, denoted by 00. In this group, there are two identical genes received from each parent. The first group in a child does not yet mean that the parents have the same group, but the gene 0 must be present in it.
2 group is denoted by the letter A. This inheritance option is possible not only if the parents also have a 2 group, but also if a null gene is inherited from one of the parents, which has a characteristic feature: it is unable to express yourself inpresence of A and B proteins.
3 group (B) is formed when one gene B is inherited from parents or in the case of a combination of genes B0.
When a child inherits from parents one gene A and another B, which are equal to each other, group 4 (AB) is formed.
All of the above will be presented in the form of a table.
| mother's blood type | father's blood type | |||
| 1(00) | 2(0A, AA) | 3(0B, BB) | 4(AB) | |
| 1(00) | 1(00) | 1(00), 2(0A) | 1(00), 3(0V) | 2(0A), 3(0V) |
| 2(0A, AA) | 1(00), 2(0A) | 1(00), 2(0A, AA) | 1(00), 2(0A), 3(0V), 4(V) | 2(0A, AA), 3(0B), 4(BB) |
| 3(0B, BB) | 1(00), 3(0V) | 1(00), 2(0A), 3(0V), 4(AB) | 1(00), 2(0V, BB) | 2(0A), 3(0V, BB), 4(AB) |
| 4(AB) | 2(0A), 3(0V) | 2(0A, AA), 3(0B), 4(AB) | 2(0A), 3(0V, BB), 4(AB) | 2(AA), 3(BB), 4(AB) |
We hope that our table "How to find out the blood type of a child, knowing the blood types of both parents" will help to understand this issue. Perhaps some parents' doubts will also be dispelled after studying it.
It turns out that the question of how to find out the blood type has a fairly simple answer. You can, guided by the knowledge of the blood types of the parents, calculate your own (although more than one option is possible here) or, conversely, calculate the maternal and paternal blood groups based on the knowledge of the children's blood group. And in order to get accurate information, you need to take a blood test for a blood type at donor points or clinics.
