Yes, both O and rh negative traits are recessive. The father is recessive for both traits. The O negative mother however, can be either homozygous dominant (positive) for rh, producing a rh positive baby. If the mother was heterozygous, having an allele for both positive an negative rh antigen, has a 50-50 chance producing an O positive child.

∙ 10y agoWe are looking for the possible blood types of a baby.
Parental information:
- Mother type B pos = can be BB or BO with Rh (++) or (+-) Genes B, O, (+), (-)
- Father type O neg = can only be OO with Rh (--) Genes O, (-)
- Baby is type BO Rh (+-) = Type B pos
- Baby is type BO Rh (--) = Type B NEG
- Baby is type OO Rh (+-) = Type O pos
- Baby is type OO Rh (--) = Type O NEG

If a mother is A pos can her child be B neg?
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.
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.
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 a Blood type O negative father and AB negative mother can daughter be A neg?
Yes. A child of theirs can either be B negative or A negative.
Can B positive mother plus AB positive father have a child that is AB negative?
Yes they can. Both blood groups and Rh factor holds two places. We see it in the AB blood group. The O blood group is OO. For A and B blood groups, the second place can be held by an O or A/B. So it can be BB/BO, AA/AO. Just as with chromosomes, (X/Y) each parent gives one of their alleles to the child. If the child is born with A blood type, this would mean the Mother had BO blood type. Now it's a matter of mix and match. Mother gives B Father gives A Child will be AB. Mother B Father B Child B Mother O Father A Child A Mother O Father B Child B The Rh factor is the same principle. It also has two places. If both parents are Pos but the child is Neg, this means that both parents had to have an Rh factor +-. Mix and match as above to see this. I wouldn't be surprised if one of the grandparents was Rh Neg. I hope this helps answer your question.
What blood type would a child be with a AB neg mother and O positive father?
The child could be A+, AB+, B+, A-, AB-, or B-. That is, any blood type except O positive or O 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
If mother is B- and father B plus can child be AB?
If my mother is b- and my dad is b+ could there be a child ab- please
Can a Type B child with a Type A mother have a father with Type A blood?
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
Can a neg mother and b neg father produce a o neg?
the geno type for O- is ( ii Rh-Rh- ) the geno type for B- is ( IBIB Rh-Rh- ) or ( IBi Rh-Rh-) they can have a child with O type if the genes was (ii Rh-Rh-) and (IBi Rh-Rh-) in a 50%. but they can't have an (O+) because both parents are Rh(negative).
If mother and father is A blood group can child be B positive?
If the mother is A, and the father is A, then the child will only have A antigens and will thus be blood type A. If father or mother are AB, then the child can end up with AB, A, or B blood type. http://en.wikipedia.org/wiki/Blood_type
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.
