What type of blood will the baby have?
At the beginning of the last century, well-known blood groups were discovered today. The Austrian Karl Landsteiner discovered that mixing the blood of different people in some cases leads to the gluing of red blood cells, and in others the opposite. This proved that the blood can be different. In addition, there are incompatible and compatible blood types. Thanks to this great discovery, safe transfusion was possible.
Blood group inheritance
What type of blood a child will have depends only on its parents. Any trait that is inherited by a child is determined by a pair of genes. In this case, he receives one from his father, the other from his mother. The baby is not given a ready blood group, but only a set of genes responsible for its formation. Thanks to their interaction, the unique blood of the unborn child is obtained. It may be the same as that of a mother or father, or it may be completely different.
What are the blood types
What type of blood in a child is determined by a set of blood proteins. There are systems for their classification. The most famous of these is AB0.It involves the division into four blood groups.
- 1 group is designated 00 and carries the name zero. It indicates the presence of the same two genes that determine the sign of the group. It also means that both parents carry the null gene. However, they do not have to have the first blood group.
- Group 2 has gene A, or rather two such genes. What type of blood a child will have, and in this case depends on the combination of the genes of the parents. It can also be obtained as a result of mixing the gene A and 0, since the latter cannot manifest itself in this case.
- Group 3 is denoted by the letter B. As in the previous scheme, in this case the group is formed as a result of the interaction of two identical genes B or a combination of B0.
- Group 4 arises as a result of the mixing of gene A and B. They are quite tolerant of each other. This group is considered the rarest.
Thus, by making certain tests for parents, you can answer the question "how to determine the blood type of the child." The laws of inheritance are objective and have no exceptions. Thanks to them, many problems related to blood inheritance are being solved today.
What is a blood test?
As already known, what type of blood will be in a child depends on the presence of certain genes in the parents. Thus, after analyzing the test results, you can establish, for example, paternity. A child with group A0 can be born from parents who have gene A and 0. For example, if a mother has AB, then the father should have A0, B0 or 00. In the case of a man carrying AB genes, then we can safely say that he not the father of this child. If the parents have the first and fourth blood groups, then the child cannot have the first one, since they do not have the necessary 00 genes. So you can determine what type of blood the child will have.For some serious illnesses or injuries a blood transfusion is required. In this case, you should talk with the mother of the baby. Perhaps the father is not the biological parent. Then the analysis of his blood should not be taken into account. What type of blood the child will have, and this should be transfused. In this case, the procedure is easier to transfer and the new blood is quickly absorbed.
