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.
What else can I help you with?
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, it is possible for a blood type B negative man to father a blood type A positive child. The ABO blood type system is inherited from both parents, with each parent passing on one of their two ABO genes to their child. This means that the child could inherit an A gene from the mother and a B gene from the father, resulting in a blood type of A 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
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.
What if mom and dad both 0 positive - and child b negative?
It is possible for a child to have a blood type that is different from either parent if both parents are carriers of a different blood type allele. In this case, the child could inherit the O negative blood type if both parents are carriers of the O negative allele.
Can an a positive mom and b positive dad have an a positive child?
no
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.
