We are looking for the possible blood types of the PARENTS.
Available information:
- Baby is Type O = can only be OO
- Father MUST contribute one O gene
- Mother MUST contribute one O gene
- Mom type AO + Dad type AO = Baby type OO, AO, AA
- Mom type AO + Dad type BO = Baby type OO, AB, AO, BO
- Mom type AO + Dad type OO = Baby type OO, AO
- Mom type BO + Dad type BO = Baby type OO, BB, BO
- Mom type BO + Dad type OO = Baby type OO, BO
- Mom type OO + Dad type OO = Baby type OO
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.
If the baby's inhibitory gene has been turned "on", then no matter what ABO genes he receives from his parents, he will test out as a Type O.

What two blood types from parents produce blood type A in child?
Parents must be blood type A or O. Any other blood type will not result in a sole A type child. It might result in several other combinations though, which are not relevant to this question.
How do you find out what blood type you are if your parents' blood types are O and A?
It's simple ask your Doctor for a "blood type" blood test. If your doctor has ever done blood work on you, he might have your type on file already!
What determains the type of blood a person has?
The parents' blood types.
Can parents both blood type O have a child with B positive blood type?
It must have one of the true parents blood types.
Can you tell if a kid is yours by parents blood type if the fathers have different?
Certain blood types are not obtainable in offspring when the parents have certain blood types.
What would your parents blood types have to be to have a child with a plus blood type?
A+ and A- A+ and O-
Do your children have to have same blood as you?
No - children do not have to have the same blood type as the parents. For example, if one parent has blood type A and the other has blood type AB, the child might have A, B or AB blood types. (For the child to have B, the parent with blood type A would need to be heterozygous, Ao)
Can 2 type o blood types have a blood type a child?
Parents of blood type O can only have children with blood type O. Because type O is recessive, you know that the parents are homozygous O.
What are blood types that are possible to have?
The blood types are A, B, AB and O. Rh positive or negative are also blood types possible. What blood type we will have is inherited from our parents.
Does your ethnicity affect your blood type?
You get your blood type (phenotype) from your parents, each of whom carry their parents blood types (genotype) in their blood. Your ethnicity plays a minor factor because some races tend toward different blood types, but any member of any race can end up with any blood type. Four children of the same parents could all have the different types of blood.
Can I find out my blood type by my body type?
Blood types are not related to body types. Blood is determined by your parents. There are 4 maternal and 4 paternal blood type possibilites. That then gives you 16 different possibilites.
Can two o blood types have an o blood type offspring?
100% of the offspring of type O parents will be type O.
