Depends on if they are homozygous (two identical genes) or heterozygous (two different genes). A+O mates with B+O and the offspring can be AB, AO, BO, or OO in equal proportions. However, if one is AA and the other BB, then 100% are AB. Finally, there is AO + BB and AA + BO. By now you can figure out the proportions.

Could a child of blood group B with a mother of blood group A have a father of blood group A?

Yes, either parent may have had a parent which carried the B antigen blood group gene. A parent that has A+ blood may also carry a dormant -RH (Rhesus monkey) gene inherited from a parent. Should the other parent have neg. RH blood type, a child may be born with B+ or B- RH blood type. In short; you need to know the blood group of the child parents & grandparents to determine whether B antigen blood group may or may not be excluded as a possibility.

Is there a possibility that parents blood type is o there baby is type A?

No. In terms of ABO groups, people inherit one part of their ABO from each parent. If you are group O you are in actual fact O/O (getting O from both mum and dad). Parents who are both group O can only have group O children.


What is the ABO blood system and Co-dominance?

This means if you get the "A" (or B) gene from one parent, and the "O" gene from another parent, your phenotype (in this case your actual blood group) will be A. The O gene doesn't produce a blood group at all, A and B genes do.
