How do you know which blood type and Rh factor will the child have by parents?

How to determine the blood type of a child by parents?

Knowing even the simplest genetics from the school program, in most cases we can determine the color of the eyes, hair and inheritance of certain diseases of their future child. This science helps us and with the definition of its possible blood group. How to find out the blood group and the Rh factor of the child by parents, we will consider in the article.

At the beginning of the 20th century, Karl Landsteiner proved the presence in the blood of specific gluing proteins – antibodies and antigens. Agglutinogens A and B were detected by the scientist on erythrocytes, and agglutinins α and β in plasma. Due to the presence or absence of these proteins, Landsteiner and Jansky created a classification of the blood groups that are used up to the present. The system is called AVO, on it the blood is divided into four groups. Later it was established that the gluing proteins are found in different variations. In addition, in the blood of 85% of people there is an antigen Rh factor (Rh +), which is also inherited.

How to determine the child’s blood type by parent: Mendel’s law in the table

Blood groups are inherited, and Gregor Mendel’s laws help identify possible variants of them. They are determined by gene I, namely by a series of multiple factors (alleles) of this gene, Iᴬ, Iᴮ, iᴼ.

  • The first two alleles are codominant with respect to each other (only when they are co-existing, blood type 4 is formed; AB)and both are dominant (suppress the second allele) in relation to the third.
  • When both dominant factors are absent in the blood, genotype 00 is formed – this is group I.
  • If there are factors A and 0 (AA, A0) – the person will have a second blood group.
  • In the presence of allelic genes B and 0, III group is formed.
