Yes. The long answer is to distinguish phenotype (the blood type A, B, AB, O) from genotype (what pair of alleles compose your genes (AA, AO, BB, BO, AB, OO).
The same goes for Rh factor (positive or negative), although the theory is more complex. The Rh + is usually taken to mean positive for the D antigen.
So parents having O (must be OA genotype) and B (must be BO genotype) blood can have a child with A ( will be AO genotype).
B negative
It's called "positive" and "negative" - yes the "A" father and "B" mother can each give a gene to produce "AB"; The Rhesus gene is either positive or negative so the baby could get either.
Definitely. One Rh positive parent is at least 50% likely to produce Rh positive offspring.
no
yes its possible
yes its possible
The mother will be given Rhogam injection within 72 hours to prevent formation of antibodies to protect the 2nd baby that he will be conceiving.
yes
No as neither carry the B gene.
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
