Can B ve mother and B ve father can give O ve son?

Answer:

Answer

If you mean blood types, yes. If both parents carry the recessive "O" blood gene there is a 1 in 4 chance each child could be type O. If you can find out the blood types of the parents' parents and even the grand parents you can narrow it down (sometimes). If you can eliminate the possibility that the "father" carries a recessive "O" he would be eliminated as a possible parent.
