Rh blood group is inherited as a triplet code so Rh positive can be CDe/cde and if both parents are this code then baby could inherit cde from both parents making the cde/cde which is the code for Rh negative blood group- ABO blood group does not affect the Rhgroup

Yes, a mother with an O+ blood type, and a father with B+ or B- can have children whose blood type is either O or B, and whose Rh is either + or -.
