Can a mom with rh positive and a father with an o negative have an o positive child?

Yes, this has to do not with the sugars (A or B, type O is a lack of either of these sugars) but with a gene that attaches the sugars to the cell surface, we'll call this gene H. If one of the parents is deficient in gene H the parent may MAKE the A or B sugars but it has no way of being attached to the cell surface so the parent looks like they are type O. If the actual type O parent contributes a functioning H gene and the other "fake type O" parent contributes the gene that codes for the A sugar the child can be type A. This is an example of recessive epistasis.

∙ 12y agoYes they can.
First off; the child will be 0 if the mom is too. If the mom is A or B the child can still be 0, but this is a 50% chance.
The child can also be Rh D positive, since the Dad is.
But the mom won't make any antibodies against the child because she is Rh D positive herself. The child and all other possible offspring after this child won't be in danger.

For a child to have a B blood type, at least one parent must have a B or AB blood type.

What if mom and dad both 0 positive - and child b negative?
Then the father of the child is someone else with B Negative blood group.
Can a A- mom have a AB- child with a O plus dad?
No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
Can an O positive mom and an A negative dad have an a positive child?
No, they cannot.
Can an O negative mom and an A positive dad have an O positive child?
No, they cannot.
Can o blood father a child with a blood type?
it is rh negative and rh positive that u dont want to mix not the a b o types it is the + or - two ++ mom n dad or two -- mom n dad not 1 positive(+) and 1 negative(-)
Can a blood type b negative man father a blood type a positive child?
yes, if the mother is either A positive or AB positive.
Can a o positive mom have a a negative baby?
Yes
When a mom who has negative blood an her unborn baby has positive blood what are the dangers?
No Danger At All, The Father Could Have A Positive Blood.
Can a mom with blood type o positive and a father with blood type b positive have an a negative child?
sadly, no. no matter what you do, a blood type B and blood type O couple cannot have a blood type A (+ or -) baby
You are positive n your mom is negative not sure what your dad is but your old brother n sister is negative can they be your full sister n brother or only half?
Upon conception, you receive an allele from your mother and one from your father. Yes these could be your full brother and sister because your father could be positive with a recessive negative allele and you could've received a positive from him whereas your siblings could've received the negative allele from him. You and your siblings can only get a negative allele from your mom because her two are negative.
If both parents are A positive can a child be B positive or negative?
Maybe. A child will have either the mother's blood type or the father's blood type. If the father is B+ and the mother is A- then it is possible that the children have the same father. So it all depends on both parent's blood type.Source: I am a 2nd year nursing student, and we had a long discussion about this subject last semester.
Can A positive parents have A negative child?
Yes. A negative Rh factor is recessive. Everyone has 2 copies of this gene (one from mom, one from dad.) Since positive is dominant and negative is recessive, if you have one of each (heterozygous), you will have a positive blood Rh, but sitll carry the gene for negative Rh. If this is the case for both parents, then the child has a 25% chance of being Rh negative.
