Yes, this will depend on the father blood type, so for a child to be B-, the father could be either B or AB negative or positive.

Is it possible for a child to have o positive blood when the father has b positive and the mother has b negative?

Yes. Each person has two genes to make up their blood group and rhesus group, one from each parent. For blood groups, groups A and B are dominant over O, and for rhesus groups positive is dominant over negative. If you have one of each, your type will be whichever the dominant one is. Firstly looking at the blood group - an O group child can be born to group B parents if both the mother's and father's blood group genotype is BO. The child has a 25% chance of being BB (group B), 50% chance of being BO (group B) and 25% chance of being OO (group O). Looking at the rhesus group - mother's genotype must be Neg/Neg, father could be pos/pos, in which case the child will always be rhesus positive, or pos/neg where the child has a 50% chance of being rhesus positive, and 50% chance of being rhesus negative.


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 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.


If one parent is O pos and one is A pos can child be B neg?

No, it is not possible for a child to have B negative blood type if one parent is O positive and the other is A positive. Blood type inheritance follows specific rules, and in this case, the child would inherit either O or A positive blood type.


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
