Determine: what children can be born in the family (with what blood group), if mom is blood type 2
Determine: what children can be born in the family (with what blood group), if mom is blood type 2, and dad is blood type 1.
If we know the blood type of the father and mother, then we can determine the likelihood of the blood type in children. If one parent has the first group, and the second has the second group, then the child can have both the first and the second with equal probability. Moreover, the mother’s blood group is not more likely to be transmitted to the child. It is impossible to accurately determine the blood group of a child in advance. There is only one case when a child’s blood group can be recognized with a 100% probability. This is when the father and mother have the first group. Then the child will have the first blood group.
