We are looking for the possible blood types of a baby.

Parental information:

  • Mother type O -- genetically OO can only give the gene O
  • Father type O-- genetically OO can only give the gene O
Baby receives one gene from each parent:
  • Baby is type OO: receives an O from each parent
HOWEVER: There is more to ABO blood typing that just the ABO gene.

There is also an inhibitory gene that will change any genotype into the phenotype O.

Therefore a person with genetically AB blood can be tested as having Type O.

  • Baby is type A+ which can be genetically AA or AO
If one parent has the inhibitory gene affecting their AA, AO or AB type,

then the Type A baby is definitely possible.
