Blood group O is caused by a recessive gene (symbol: i). The mother must therefore be homozygous (ii). The offspring must, like Mum, have two copies of the recessive gene, and one of these must have come from Dad. So the father's possible genotypes are IAi (blood group A), IBi (group B), and ii (group O), all of which include a recessive gene that could be passed on to the offspring.
The father's blood type can be anything really if the children have an o positive blood type and the father has an A+ blood type it just shows you that the mothers blood type was the dominate trait and took over theA+ causing the children to have 0+. i am about 90% sure i think this is right i was just learning about this in school. But i will continue to look it up for further information.
We are looking for the possible blood types of the FATHER.
Available information:
Generally, as long as Dad contributes the 2nd O gene, that's what's important.
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.

Baby receives one gene from each parent:
The father can be heterozygous for Types A & B or he can be Type O.

It is possible for parents to be either type A, B, or O.
Both parents must carry at least one copy of the "O gene".
Technically speaking there is no O gene, because group O individuals lack the group A or B specific genes altogether.
Therefore, in order for a child to be born with type O blood, both parents must be heterozygous or homozygous for O.
They could still be considered group A or group B because the genes for A and B are dominant, but each parent must carry only one of either of these genes.
The blood type of the parents have little effect on the blood type of the child.
A babies blood from that scenario can be one of the following:
A, B, AB or O. So yes a babies blood can be O even if the blood of the father is B and the mothers is A.
possible blood group is "A" "B" or "O"plus.
The child could be either A or O.
blood group "B" or "O"positive.
The blood would be A+, the child's is always pretty much what the Father's is.
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).
Yes, people with any blood group can have a child.Problems can occur if the mother is Rh negative, and the baby is Rh positive - because the antibodies of the mother may act as if allergic to the baby.There should be no problems with a Rh positive mother.
You should be able to. O type blood is usually described as the universal donators of blood because all body systems should accept in the blood system.
I was told that a mother that is a+ and child is 0+ that it OK for the father to be 0-
a-
The blood would be A+, the child's is always pretty much what the Father's is.
Blood types are received from the mother and father, so the child can be the same type as the mother if the father's type allows it.
He mother and father have nothing to do with the child's blood type
The blood type should be O positive.
It should be b-
Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.
No, because a baby gets their blood from their father, not their mother.
Possible blood types of the child with a mother who has A blood type and a father who has AB blood type are A, B, and AB. :)
Yes, a father with A negative blood can have a child with A positive blood. If he does, the mother must have a positive Rh factor, and the mother's blood type may be any of the possibilities.
can a mother of o blood group have a healthy child with a father type o
If the mother is A, and the father is A, then the child will only have A antigens and will thus be blood type A. If father or mother are AB, then the child can end up with AB, A, or B blood type. http://en.wikipedia.org/wiki/Blood_type
