If one parent is A pos and the other is A neg is it possible for the child to be O?

So it follows that:group A can be A/A or A/Ogroup B can be B/B or B/Ogroup AB can only be A/Bandgroup O can only be O/O.
In this case the child's parents must both be A/O.
You can only tell if a person is A/A or A/O by looking at their ancestors' blood groups.
The Positive/Negative bit is to do with the rhesus (Rh) blood group system and is pretty complex. It has nothing to do with and is completely independent of the ABO system.

What are the possible blood types for the parents of a A neg child?
A + ; A - ; Ab + ; Ab -; O- ; Any ONE parent may carry these, taking into account the possible masks of the target group
If one parent is O pos and one is A pos can child be B neg?
No
Can a b neg father have an A pos son?
A father with the blood type can be b negative can have a child even a son that is A positive. The blood of a child comes from one or the other parent. If the mother is A positive the child can be as well.
Can an A rh neg and B blood group produce an A rh Positive child?
Yes. If the A rh neg parent has genotype A/A or A/O and rh-/- and the B parent has genotype B/O and rh+/- or +/+ The first parent gives their A to the child and the second partner gives a rh+ (but not their B, and this is why they cannot be B/B) to the child. The child ends up with genotype A/O rh+/-, which would be expressed as blood group A rhesus +.
Can a B positive mother and a AB positive father produce a O negative child?
We are looking for the possible blood types of a MOTHER.Available information:Father type O pos -- can only be OO with Rh (++) or (+-)Genes: O, (+), (-)Baby type O neg -- can only be OO with Rh (--)Baby receives one gene from each parent: Mother must contribute an O and Rh (-)Blood type AO with Rh pos (+-) or neg (--)Blood type BO with Rh pos (+-) or neg (--)Blood type OO with Rh pos (+-) or neg (--)With the father contributing an O and (-) gene, the mother mus contribute the other O and (-); therefore the mother can be Type A pos/neg, Type B pos/neg or Type O pos/neg, with Type O neg being the best case of getting the O neg baby.
How does a child get the A neg if both parents are positive Mother AB father O?
Each parent has two genes for Rh factor. If one of them is on and the other off in both parents, the child has a 25 percent chance of being Rh negative.
If parents are o neg what type will child be?
it might be o neg or a,b,o,a neg and posi,b neg and posi
Can an o positive mother and a a neg father produce a ab neg child?
no
O pos and b pos parents have a a neg child?
No. Two Rh positive parents can have an Rh negative child. A parent with blood type O lacks the A antigen; a parent with blood type B also lacks the A antigen; therefore they cannot have a child together with blood type A.
What type of blood will a child have if both parents are positive types?
The child will probably be positive, but they can be negative. Each parent has two genes for pos/neg blood type. The parent will have positive blood type if at least one of their genes is positive, but they could both also have negative genes to pass on to the child.
If both parents are o plus does this affect the child or cause birth complications?
Both parents having the same blood type should never be an issue. There can be issues when one parent is a neg and the other is a positive. The issue is rare though.
Can an O neg mother and an A neg father produce a child that has AB blood type?
No, This is impossible!
