Question:
Married couple adopt a male child a few years later twin boys were born to them the blood group of three sons is a positive B positive and O positive, what is the blood group of the adopted son.
Answer:
It may be B positive or even O positive as well. If the twins are faternal then the adopted son may have any of the blood group and if the twins are not faternal then the adopted son will be different blood group than the twins.
Explanation:
It is quite impossible to judge the blood groups of the boys. Since, in the question it is stated that, two of them were twin so, there blood group must be same. Why not, identical twins will always have the same blood type because they were created from the similar fertilized egg. In the question two blood groups are stated such as, O positive and B positive. And the adopted son can have any of the blood group because may the other children be twin but it is not stated that whether they are faternal or not because, faternal twins may have different blood groups and if the twins would be identical then the adopted son would have obviously different blood group other than the twins.
