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.


Child o positive mother o positive father a positive is this positable?

Yes, it is possible for a child to have O positive blood type if one parent is O positive and the other parent is A positive. The child could inherit the O allele from the O positive parent and the A allele from the A positive parent.


If one parent has o neg and one o pos can you have a B neg?

An O mother and an O father will always have an O child. They cannot have A, B or AB. As far as the Rh factor the baby can be positive or negative. There are rare instances when this will not be accurate. In the case of a mutation, the blood typing may not hold true in the question of parentage. Ask before you act! A DNA test will give a final definitive answer.


Can a child that has a blood type of O have at least one parent that is AB?

We are looking for the possible blood types of a baby.Parental information:Mother type A pos -- genetically AA or AO and Rh (++) or (+-)Father type O neg -- can only be OO and Rh (--)Baby receives one gene from each parent: Baby is type AO (+-) = Type A posBaby is type AO (--) = Type A negBaby is type OO (+-) = Type O posBaby is type OO (--) = Type O negNOTE: There is no gene B here to make the AB blood. Generally the baby will be either Type A pos/neg or Type O pos/neg.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.What if baby is Type AB?If type O parent has the inhibitory gene affecting his BB, BO or AB type,then the Type AB baby is definitely possible.


If your father is type o positive and your mother is type ab negative what is the possible blood type of a 6th child?

These are the possibilities: A neg or A pos B neg or B pos The father will always give an 0 to the child, which is infact zero. The mother will give an A or a B. An A and 0 gives A An B and 0 gives B The rhesus factor can be positive or negative.

What are the possible blood types for the parents of a A neg child?

The parents could be any combination of blood types that includes A and Rh- factors. Potential blood types for the parents could be A neg and O neg, A neg and A neg, A pos and A neg, or A pos and O neg, among others.


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.


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.


If the parents are blood Type A neg and Type O pos could they have a Type A pos child?

We are looking for the possible blood types of a baby.Parental information:Mother type A neg --can be AA or AO with Rh (--) = contributes A, O, (-)Father type O pos --can only be OO with Rh (++), (+-) = contributes O, (+), (-)Baby receives one gene from each parent: Baby is type AO with Rh (+-) or (--) = Type A pos/negBaby is type OO with Rh (+-) or (--) = Type O pos/negYES, these parents could produce a Type A positive child.


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 A positive blood types can the child be O positive?

Yes, the possibilities are A pos or neg and O pos or neg, see the related link.


Does a negative and a positive make a negative?

yes, 1 neg. + 1 pos. = neg. 2 neg. = pos.


Which direction does voltage travel?

conventional theory is pos to neg. electrical theory is neg to pos.


How do you wire two 6 V batteries and one 12 V?

It depends on how much voltage you want/need. If you want 12 volts total then hook the 6 volt batteries together by connecting one pos to the others neg. Then put the remaining pos and neg to what you need. You can add the 12 volt with these by connecting it directly to the use. If you want 24 volts then just go pos to use neg to pos on next battery to neg to pos on next battery then neg to use


Converting from points to electronic ignition are the wires connected pos to pos or pos to neg on 305 Chevy on coil?

remove resistor from loop positive to positive terminal neg to neg


Battery wiring 48v club car?

hook 2 batteries pos to neg and 2 more pos to neg, now you have 2 at 24v and hook the 2 pair pos to neg


If mothers blood group is O- and father is AB plus what will be a child blood group?

We are looking for the possible blood types of a baby.Parental information:Mother type O neg = can only be OO and Rh (--) Genes: O & (-)Father type AB pos = can only be AB and Rh (++) or (+-) Genes: A, B, (+), (-)Baby receives one gene from each parent: Baby is type AO Rh (+-) = Type AposBaby is type AO Rh (--) = Type A negBaby is type BO Rh (+-) = Type B posBaby is type BO Rh (--) = Type B negIf the parents are O neg and AB pos, they can have a Type A pos/neg or Type B pos/neg baby.
