indicated by not entirely understandable characters? Consider all these
the questions in this article and below you can calculate the group
blood of your child on a special table.
A bit of history
Future winner of the prestigious Nobel Prize, Austrian
researcher Karl Landsteiner, conducted an interesting experiment.
Taking blood from a few like-minded employees, including
including himself, he divided it into a liquid component, serum, and
red corpuscles – red blood cells. Mixing in various ways six
samples, the scientist found that in the serum of some red blood cells
evenly distributed, while others are glued together and then deposited on
bottom. During the experiments, scientists identified three different
human blood groups, which they labeled A, B, and O.
The fourth, discovered six years later by Dr. J. Jansky, is more likely
all, just absent from the participants in the experiment.
Czech researcher proposed to designate blood types
in a different way, in Roman numerals, and in 1928 symbolism was adopted,
which is used now – 0 (I), A (II), B (III) and AB (IV).
It has been proven that not all donated blood is suitable for a patient when
its transfusion is required, and only the corresponding group. In honor of
Landsteiner’s greatest discovery that helped save lives
million people, International Day of the donor is celebrated on the day of his
Birth – June 14th.
What is blood
The division of blood into groups is based on the presence of
erythrocyte specific antigens a and b and looks like the following
in the following way:
– I (0) – no antigens in the blood;
– II (A) – the presence of only antigen A;
– III (AB) – the presence of antigen B;
– IV (AB) – on the surface of the erythrocyte there are both, A and B.
Antigens are reliable body guards located in
surface red blood cells. When a virus invades, they
instantly start active production of antibodies that reliably
stick to it and immobilize.
What determines the blood type of the child
Timely determination of the blood type of the child is extremely
important. After all, if necessary, its transfusion can be

This is for young children, which is why they take blood for analysis already in

geneticists have proven that this indicator, like many other
signs inherited from mom and dad. Gregor Mendel considered
founder of genetics and known for his experiments with peas, in
mid-19th century formulated the laws according to which the group
the child’s blood inherits the parental parameters (you can clearly
see this in the special table of the child’s blood type). Short
it looks like this:
– mom and dad are owners of the same blood group I (0) –
antigens A and B of the heirs will be absent;
– parents have a combination of groups I (0) and II (A), or I (0) and III
(AB) – the blood type of the child is similar to the parent;
– spouses IV (AV) – possible options, the blood type of the child
any except I (0);
– if the parents of the baby have II (A) and III (AB) – predict
It is quite difficult, in the kids any group is equally possible.

lovers of bread, but the owners of IV (AB) are quite capable of becoming

Rh factor and blood type of the child
On erythrocyte membranes in the vast majority of the population
the planet is a lipoprotein, a special protein, this is the mysterious
Rh factor, which designate in Latin letters Rh. Its availability
confirmed in approximately 85% of the world’s population, their blood
therefore, they are called Rh-positive. In the absence of protein, why
blood does not get better or worse, they say that a person
negative rhesus. The letters Rh are used with “+” or
�”-“. If the potential parents of the baby have no protein, then
the long-awaited child he will not appear, whatever the blood type of the child
The presence of + Rh in both parents guarantees its appearance in
heirs in 4/5 of all cases, although 1/5 remains possible
the option of having -Rh. But if the father of the baby -Rh, and the mother
+ Rh, or vice versa, then the crumbs are quite likely both the presence and
lack of lipoprotein. Thus, the Rh factor, as well as
blood type of the child depends on the factor of heredity.
Blood compatibility of potential parents

They know that the success of conception, the health of the future of the little ones and
the well-being of a gestation period is directly dependent on their

Blood type – is incompatibility possible
Not only the Rh factor plays a crucial role in the prosperous
conception and birth of a strong baby. Compatibility is equally important.

This is indicated by the table below. She lets you see
that conflict may occur in the following cases:
– I (0) and negative Rh factor in mom determine
the possibility of conflict with proteins of the second group A, the third group B and
– II (A) with negative RH – conflict with proteins possible

– III (AB) and negative rhesus may conflict with proteins
of the fourth group A, the second group A and protein positive
– IV (AV) – the most non-conflict group, trouble can
occur only with -RH in mom and + RH in dad.
If the mother, for example, I (0), and the child’s blood type
inherited from the father and different from the mother
the pregnant woman will start to produce antibodies against him – antiA and
