To best explain the answer, the ABO and the Rh should be examined separately.
For the ABO, the child is likely to be type B since B is dominant against O.
Each parent's allele pairing is either BB or BO (both result in Type B). If at least one of them is BB, then the child is guaranteed to be type B. If both are BO, then there's a chance of recessive inheritance; both parents could pass on their O allele, producing a child with Type O blood.
For the Rh, the child is likely to be Rh+ since + is dominant against -.
Like with the ABO, each parent's allele paring is either ++ or +-. If one parent is ++, then the child is guaranteed to be Rh+, but like with the Type O child, an Rh- child is possible if both parents are +- and both pass the -.
What else can I help you with?
Can an B positive blood type mother and an B positive blood type father parent an A positive child?
No. The child will be type B or O, it cannot be type A.
What blood type would a child be with a AB neg mother and O positive father?
The child would most likely have either blood type A positive or B positive. A child inherits one blood type allele from each parent, so with an AB negative mother and an O positive father, the child could receive the A allele from the mother and the O allele from the father, resulting in blood type A positive. Alternatively, the child could receive the B allele from the mother and the O allele from the father, resulting in blood type B positive.
Can a B positive father and b negative mother give birth to AB positive child?
Yes. If the father is the AO variety of A, he can contribute an O and the mother can contribute the B, making a BO variety of B for the child. And, the father can give the Rh positive while the mother gives an Rh negative, which will be an Rh positive.
If mother blood is b negative and father blood is ab positive what is child's possible blood group?
If the mother's genotype is BB, the child can be type B or AB (50/50 chance). The child cannot be type A or O. If the mother's genotype is BO, the child can be any type, tho B or AB is more likely. The Rh factor is likely positive but can be negative. So, without knowing the mother's genotype, and the father's specific Rh factor (++ or +-), we cannot be sure.
Can a o positive mother and o negative father have a b negative child?
Yes, it is possible for an O positive mother and an O negative father to have a B negative child. The child would have inherited one O gene from the mother and one O gene from the father, but could have received a B gene from each parent, resulting in a B blood type. The negative Rh factor would have also been inherited from the father.
If Mother is O positive and father is B positive can child be B negative?
Yes, if the father is heterogeneous positive.
Can a child be B positive if mother is O negative and father A positive?
No, the father would have to have B or AB.
Can the child be type b positive with father type a positive and mother type b?
NO
Can Mother B positive Father is AB positive Can child be A positive?
yes
Can an o positive father and a b negative mother have a child with a positive?
No. They can have an O positive, an O negative, A B positive, or a B negative child.
What are the possible blood types for a child with a mother who is O positive and a father who is B positive?
B positive
If mother is B positive and father is A positive what will be the blood group of child?
Blood type A/B
Can a o positive mother and a b positive father have a o positive child?
yes
Can a father o positive and a mother b positive have a child o positive?
yes
Can a b positive mother and an A positive father have an O negative child?
Never
If the mother is b negative and the father is a positive how is the child o negative?
The mother must be heterozygous b and the father must be both heterozygous b and heterozygous positive.
Can o positive mother and b positive father have b negative child?
That depends on if you make love with the actual father
