We are looking for the possible blood types of a baby.
Available information:
- Mother type AA = contributes A gene only
- Baby is type O --can only be OO = must get O gene from each parent
- Mom type AA + Dad type AO = baby type AA, AO
- Mom type AA + Dad type BO = baby type AB, AO
- Mom type AA + Dad type OO = baby type AO
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 blood type can a child have if their dad has type AO?
If the father is type AO, the types of blood that the child can have depend on the mother. If the mother is AA, the child will be either AA or AO. If the mother is BB, the child will be either AB or BO. If the mother is OO, the child will be either AO or OO. If the mother is AB, the child will be AA, AB, AO or BO. If the mother is AO, the child will be either AA, AO or OO. If the mother is BO, the child will be either AB, AO, BO or OO. So, of all the possible outcomes, the child will be either AA, BB, OO, AB, AO or BO.
Could a child with type O blood have a blood type A father. explain?
Yes. The blood group O can have the alleles AA and AO. The father must have the alleles AO for the child to have the blood group O (With alleles OO). The O from the father's AO was inherited to the child. The mother's O was also inherited by the child so the mother can have bloog groups A (AO), B (BO) or O (OO).
Could Father and Mother with A blood group have child with O blood group?
It depends on the genotype of the parents: If they are AO and AO the child could be all of the 2 Bloodtypes: AO (= bloodtype A) OO (= bloodtype O) If they are AA and AA the child could only be bloodtype A The answer in short: yes!
Can a child have ab positive blood type from a A positive mom and o positive dad?
Not possible. If the mother is A+, there are two possibilities, AA or AO, and if the father is O+, there is only one possibility, OO. therefore, the only possibilities of the child's blood type will be either A [AO] or O [OO].
What blood type a baby will be if father is o and mother is a?
The genotype of the father is certainly OO (because blood type O is recessive). The genotype of the mother however can be AO or AA (both give blood type A). The baby will have a combination of the genes from the mother and the father (one of each) and so: - If the genotype of the mother is AA and the genotype of the father is OO, the baby will certainly have AO as genotype and has therefore blood type A. -If the genotype of the mother is AO and the genotype of the father is OO, the baby can have AO or OO as genotype. AO results in blood type A and OO in blood type O (50% chance).
What blood type a baby will be if father is a and mother is o?
The genotype of the father is certainly OO (because blood type O is recessive). The genotype of the mother however can be AO or AA (both give blood type A). The baby will have a combination of the genes from the mother and the father (one of each) and so: - If the genotype of the mother is AA and the genotype of the father is OO, the baby will certainly have AO as genotype and has therefore blood type A. -If the genotype of the mother is AO and the genotype of the father is OO, the baby can have AO or OO as genotype. AO results in blood type A and OO in blood type O (50% chance).
What is the blood type of the father if the mother is O plus and the child is A?
Must be AA, or AO because the mother having O blood, which is homozygous recessive, must be OO. The signs mean little here except the father must carry them and the child inherited them from the father.
Mother is O plus father is AB- what will child be?
Depending on what kind of A the mother is, the baby can be either O or A. If the mother is homozygous A (AA), the child would be A for sure. If the mother is heterozygous A (AO), the child can be either O or A. This is because the A allele is dominant over the O allele, and each person has two alleles for the ABO blood type. The father's O alleles (OO) are recessive so it all depends on the mother.
If the mother has type A positive and father has type O negative what type blood will the baby have?
They would most likely have O Type A blood is really type AO blood, (B= BO) So if you have Type... O and AO, they would most likely be O To the above answerer, Type A blood can be AA blood. If the mother has AA blood, the child will have AO blood no matter what. If the mother has AO blood, The baby might have OO or AO blood. (O blood can only be OO) Not too sure about if negatives or positives affect the baby's blood type though.
If the mother has a positive and the father has o positive what blood group is baby?
In any case, the baby will have Positive blood type. If the mother is AA+ the baby could only be AO+ or AA+. Which always results in A blood type baby. If the mother has AO+ then the baby could have AO+, AA+ or OO+ with the fallowing ratios: 1/2 - AO+ 1/4 - AA+ 1/4 - OO+ which means there is a 3/4 chance of A+ blood type and 1/4 chance of O+.

Could a child with type B blood have parents that both have type A blood?
No, it's not possible. Someone with type A blood has the genotype AA or AO, so if both parents are type A their children could only be type A or type O. eg if the mother was genotype AA and father also AA, their children could only be AA (i.e. homozygous for blood type A), but if the mother were AO and the father AO (i.e. heterozygous), then their children could be AA, AO, or OO (i.e. blood type O). If the mother was AO but the father AA, then their children could be AO or AA but not OO. This is due to the way genetic information is passed from parent to child; male gametes (sperm) contain 23 paternal chromosomes and female gametes (egg) contain 23 maternal chromosomes, so when they fuse at conception to form the foetus (46 chromosomes as everyone has, except those with certain genetic disorders), it has 50% genetic information from the father, and 50% from the mother.
Will mother with o negative blood type have child with o negative?
The fathers blood type has to be taken into consideration aswell, if he is tpe o the the baby will be o, but if he is ao or bo then the child could be ao or bo or oo, if he is ab the the child will be ao or bo, if he is AA the child will be ao, if he is bb the child will be bo. Not sure about the negative tho.
