How is the blood type of children and parents interconnected? Rules of succession

Sometimes very serious scientific topics become popular and relevant for ordinary people. This applies to the inheritance of genetic traits and information, for example, about how the blood type of children and parents is interconnected. This question becomes most acute under one of two circumstances: determining paternity and finding a donor for transfusion in case of emergency. In principle, everyone should know how to solve a problem for themselves in the second situation.

Should the blood type of children and parents coincide completely?

Every man always wants to see in his offspring his own external features. But there are cases when the baby grows like two drops of water like a maternal grandfather or some other relative. And as a result, in some cases doubts about true fatherhood creep into the soul of the head of the family. The situation may be especially acute when determining the blood type of the baby, after which it threatens peace and family well-being. Indeed, some people think that the blood type of children and parents should coincide in the literal sense of the word. Otherwise, for a man this is tantamount to proving treason. Let's look into this serious issue, preventing problems in the family.

How is blood type inheritance from parents determined?

The most reliable way, of course, is to determine this genetic trait by taking tests. But long before the birth of the baby, one can guess what kind of blood type he will have. The table below shows the inheritance rules. The middle part at the intersection of these parents corresponds to the blood type of the child.

Blood types of children and parents may be completely different

Here are some examples of putting into practice the data shown in the table. For example, if the father has the first blood group, and the mother has the fourth, then the birth of a baby with a second or third blood group is likely. Or there may be situations where inheritance occurs without any rules at all. With a combination of the second and third blood groups of the parents, the baby can have any of all possible.

Blood type of parents and children: transfusion compatibility

Unfortunately, it happens that in unforeseen cases (during surgery, after an accident), the parent, with all his will, cannot help his own child. And all due to the fact that his blood type does not meet the requirements. Therefore, you should familiarize yourself with the principles that rely on for blood transfusion. In our country, these recommendations are not fully followed, preferring to use only the exact coincidence of group numbers and Rh factors.
