The Kid's Blood Group - The Circle Table helps

Can not two A's just be A's?

In defining blood types, the AB system (A, B, AB, and 0 phenotypes) and the Rh system (which can be Rh + or Rh-) are known to everyone, and this is the basis for the knowledge of the blood type of the newborn baby. - However, what fewer people know is that each blood group is defined by two genotypes (descent and maternal). Variants A and B predominate over variant 0. Based on these, if someone has a blood type A, or A A or A 0 is the genotype that has an effect on what the baby's blood type will be - he explained to us Anna went, a biologist at the Geneva Diagnostic Center of God. If the two are all the same, they are homozygous, while if they are different, we can speak heterozygous. Blood tests for blood group A contain A, for blood B, for B, for AB, and for A and B, while there is no antigen in blood 0. - Based on these, blood group A can be A A or A 0 genotype, B is B B or B 0, 0 is only 00 and AB is only AB. Therefore, it is possible that two people of the blood group may have A, but up to 0 children of the blood group, even if a parent with blood groups A and B can have any of the phenotypes, the expert said.

What is the baby's blood group like?

Thus, the baby may pass on the following blood groups based on the mother's and father's blood type:
Father's blood group





Mother's blood groupTHEA, 0A, B, AB, 0A, B, ABA, 0
BA, B, AB, 0B, 0A, B, ABB, 0
0A, 0B, 0A, B0

The role of the Rhesus factor

In fact, the Rh factor, or Rhesus factor, is found in the white blood cells, which is capable of producing antibody production. It is important to be clear about this because, in some cases, the mother's body may produce antibodies to the fetus. - The Rh factor is over-dominated by +, so if one parent is Rh +, the other is Rh-, so the baby will definitely be Rh +, and can only be a child Rh- if Rh- the mother and father is - the biological is amazing.

If the blood group is incompatible

There may be a problem with expectation if the mother is Rh- and the baby is Rh + (because her father is also Rh +). "During the first pregnancy, there is no problem, because the mother does not have direct contact with the fetus's Rh + blood," the expert explained. However, in the second pregnancy, if the previous child was Rh + and the second fetus is Rh +, the mother's body produces an antibody that causes the fetus to have red blood cells. To avoid this, the mother receives D-antigen during the first pregnancy. - It used to be in practice to check the baby's blood group, but even if it is not done by itself, it is worth checking out - the specialist added - because there are many life-threatening, accidental, you need to be clear with him.Related articles in this topic:
