Is blood type inherited from the father or mother?

In fact, blood type is a representative symbol and does not have much function. The main purpose of blood type is to determine who a person's blood type is similar to, so that timely precautions can be taken during blood transfusion. There are many types of human blood types, but not everyone has them, and examinations need to be done based on personal physical conditions.

Blood type is a classification based on the differences in homologous antigens on the surface of human red blood cells. Due to the different agglutinogens contained in human red blood cells, blood is divided into several types, hence the name blood type. Blood type is based on a person's red blood cells

There are many types of human blood types, and each blood type system is determined by genetic factors and has immunological characteristics. The most common blood type system is the ABO blood type, which is divided into four types: A, B, AB, and O; the second is the Rh blood type system, which is mainly divided into Rh positive and Rh negative; and the third is the MN and MNSs blood type systems. According to current clinical tests at home and abroad, there are more than 30 types of human blood types.

Human blood type is hereditary. When the blood type genes of both parents combine in the sex cells of both sexes, they can pair up in the chromosomes of the cell nucleus, thereby passing the blood type genetic characteristics to offspring. Different blood types have different genetic genes:

The genetic gene for type A blood can be the combination of A and A of both sexes to form AA, or it can be the A gene of one sex combined with O of the other sex to form AO. But no matter whether it is AA or AO, the blood type that is displayed is type A, and O is a recessive genetic gene and cannot be expressed.

The genetic genes of type B blood are similar to those of type A blood. Some are BB, some are BO, but all that appear are B.

The genetic genes of AB type and O type blood are consistent with the blood type they express, AB type is AB and O type is OO. From this we can see that if the father and mother are type A or type B blood, their children may be type A or type B, but they may also be type O, because type A or type B both contain the recessive genetic gene O. When the O in the father's genetic gene combines with the O in the mother's genetic gene to form OO, it manifests as type O.

The various genetic genes of the parents' blood types will be recombined when the two sexes combine, and then reorganized to form the various blood types of their children. There is a certain blood relationship between children and their parents' blood types, but they are not necessarily the same.
