Do the parents determine the blood group of a child?

The parents will determine it yes, but as both parents carry a dominant and recessive set of genes, the child may not have the same blood type of the parents. For example, both of my parents are O+, but carried a recessive A+ gene, I have A+ blood.
Yes child will have either mother or father's blood type
Yes they do.
Yes a child gets half of it’s DNA from it’s father and half from it’s mother.
yes - a child's blood group depends on those of the parents and how they combine.
yes they do although you will not always get the same blood group all genetics are decided by the parents genes.
Yes, Children have either their father or mothers blood type or a combination of the two.
yes the parent detemine the blood group of their biological children
yes they do.
Blood type is genetic. That means that the mother and father each contribute one gene to the child. The genes are A, B & O.

Blood type A = AA or AO
Blood type B = BB or BO
Blood type AB = AB
Blood type O = OO

The child, then, may be a different blood type than its parents. If Mom is AA and Dad is BB, then all the children will be AB.

So, to answer your question, yes, the parents determine the blood type of the child.

(alis_n_1derland is mistaken, as A is dominant and O is recessive. If both her parents are O and she's A, then she is NOT the biological child of those two people!)
Only if they reach an agreement on that.
No, Social Services take a vote on it! Of course they do! Who else would be involved?
yeah. well, it goes like this. there are two factors. the presence of A or B (i believe these are proteins?) and the presence of the Rh factor. there are 8 blood types. A+ (positive meaning Rh is present) B+, AB+ (which has both A and B present and can take any other blood type in a donor situation. the rule for that is, you can't add anything that isn't already there but AB+ can take anything because it has everything) O+, A-, B-, AB-, and O-. (O- can donate to any other blood type because it has nothing present. O indicates the absence of both A and B)

I'll give you an example of how this can work with passing blood types on to babies. My blood type is O+. so i dont' have A or B but i have the Rh. My husband is AB-. Our son's blood is A+. husband passed on the A but not the B and our son got the Rh from me.
yes, but its all in the genes,
yes & no because some children can have the same blood type as one of their parents but most of the time genetics determines the blood type for example One parent can be "A-" the other "B+" and the child can have "O" blood type. But one of the child's grandparents could have "O" blood as well. I hope that answers your question?
Hi yes they do, basically what happens is that every person has two versions of each gene (called alleles), one from their mother and one from their father.

Eg. If you have brown eyes you have the gene which gives your eyes colour but you may have one version which is from your father which says 'blue' and one from your mother which says 'brown' the brown allele for eye colour is dominant over the blue (which is called recessive) so your eyes will appear brown even though you have both brown and blue versions of the eye colour gene.

It is the same for blood group except the dominance goes as such

blood groups A and B are codominant (ie they are equal) and O is recessive therefore there are 4 possible blood groups (O \ A \ B and AB (if you forget about the rhesus + \ - for a minute))

So if you have blood group O you can only have the genotype OO
If you are blood goup A you could be AA or AO
If you are blood group B you could be BB or BO
and if you are AB you can only have the genotype AB

therefore if your parents are both blood group O then the children will only ever be blood group O as their genotype will be OO (no other dominant blood group allele present) so the combinations you can get are only ever OO (rememberinbg you have 2 versions of the allele) (m=mother f=father)
M = OO and F=OO
posible combinations



Hoever if your mum is say AO (blood group A) and your dad is BO (blood group B) you can get the following combinations


Each combination from the sqare has an equal chance of occuring so the possiblity of a child having blood group O from the example directly above is 25%.
The resus factor is just an extra identifier and works on the same sort of principal, where + is dominant and - is resesive so in order to be resus +ve you could have the genotyp ++ or +- but to be resus negative you have to have the genotype --

So in conclusion Yes you parents do determine your blood group along with any other genetic factors that you have.

I hope this sort of helps, it's quite difficult for me to explain by writing it down but i tried :-)
yes they do as it is genetic
Well if they do where the hell do I come from.
My father Is A+ My mum is O+ my 3 sisters are 0+ But me I'm
A (D) RH Neg.
yes they do
