The blood type is the most important part of human life which everyone has to know since the birth. For this reason future parents worry and want to know for certain what it will be.
Instruction
1. Often parents too worry about yet not been born children. It is explainable. Yes, happens, these concerns are beyond decency, but sometimes they happen and are reasonable. Namely, most of parents want to know a blood type of the child with absolute confidence. First, the easiest way, it to go to hospital. From mother and the father of the child will take blood. Then will tell what blood types at them and what chances at the child to receive the same group.
2. Secondly, all know long ago that the father and the child has an identical blood type. This similarity is confirmed in seventy-eighty percent of cases. Therefore it is enough to visit only to dad hospital and to make blood test. But nevertheless remained twenty-thirty percent of children by inheritance do not receive the same blood type as at native dad, and in connection with pre-natal diseases the pathological changes which cause blood changes have absolutely other than fatherly group.
3. It is also possible to look at the table of compatibility of groups of the father and mother. If both parents have the first group, then with absolute confidence it is possible to declare, as the child will have the first; if at someone from parents the first group, and at another the second, or at the both second, then the child has chance exactly of a half to receive the first or second blood type. With the third group it is harder and harder. The child of parents, one of whom has blood type number three, receives one of four approximately in twenty five percent, but what, nobody will tell as there are no guarantees any.
