In the beginning of the last century, scientists proved the existence of 4 groups of blood. How are inherited by child blood group?
The Austrian scientist Karl Landsteiner, mixing the serum of some people with red blood cells taken from the blood of others, found that for certain combinations of red blood cells and serum is “bonding” – the clumping of red blood cells and clots, while others have not.
Exploring the structure of red blood cells, Landsteiner discovered the particular substance. He divided them into two categories, A and b, highlighting the third, where he carried the cage in which they were not. Later, his disciples – A. von Decastella and A. Storli – found cells containing the markers and type at the same time.
The studies have any system of division into groups of blood, which was called AVO. This system we still use today.
I ( 0 ) – blood group is characterized by the absence of antigens A and b;
II ( A) is installed in the presence of antigen A;
III ( AB ) – antigen;
IV( AB ) – antigens A and B.
This discovery made it possible to avoid losses if transfusions caused by incompatibility between the blood of patients Continue reading

Somehow in one of the channels has told a shocking fact: the average dad working 12 hours a day, pays to communicate with your child 4 minutes per day. Apparently our fathers feel that they are only required material support of the family, and the care and education fall on the shoulders of mothers.
The lack of male parenting affects child development . The boys don’t see in their lives the example to follow, no one teaches man’s duties, they can grow limp or fall into bad company. Girls who grow up without a father, do not know how to build a normal relationship between a man and a woman, they can connect their life with the first guy because in childhood they lacked male affection, attention, a sense of security.
It is therefore important to establish the relationship between father and child. Because man, unlike women, are much more difficult to feel your paternal instinct. Man is by nature trapped and bound in their emotions, so the mother must help her husband to establish contact with the baby.
