The O blood type is always recessive; A and B are codominant and dominant to O. The O blood type is represented with both O alleles, and the AB blood type is represented with one A and one B alleles. The child will either have a genotype AO or BO, but the blood type will be expressed as A or B. This cross can be demonstrated easily with a Punnett square.
For the Rh factor. This is dependent on the mother's genotype since the father carries the recessive alleles. The Rh factor for both homozygous and heterozygous dominant cases is positive. Thus, if the mother is heterozygous there's a 25% chance that her child with have be Rh+. If she is homozygous dominant, her children will always be Rh+. This can also be demonstrated with the Punnett Square.And that is the answer

What blood type can a baby be if the father and mother are both type B positive?
The baby may be any of the following: * B positive * B negative * O positive * O negative
Can a mother with a negative blood and father with o positive blood have b positive blood group baby?
No. For a person to be "O" blood type, they have a phenotype of O, which can only come about if they have a genotype of OO. If both mother and father are O's then they have no B that they can donate to the baby.
A Father with A positive blood type and a mother with O positive blood type will have a baby with what blood type?
The baby will normally be A positive.
Can a mother with b plus blood type and a father with b plus blood type have a baby with a blood type?
Yes, it is possible. The geneotype of the mother would be either BB or BO and for the father would be OO. If you cross the father's geneotype and either of the mother's then at least two of the four outcomes will be for B blood type. As for the - and +, positive is dominant over negative. The father could be + - or + + and the mother would be - -. Either combination would result in at least two positives. Therefore, it is possible for the mother to be B-, the father to be O+ and the baby to be B+. I added the link to the website where I got my info from. I want to know if an rh b neg blood type mother and an O positive father can have an A positive baby?

No
Can a O negative father and A positive mother produce a AB positive baby?
the baby may be A or O.
Can a mother have a positive and father have b positive can have baby with o positive blood group?
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
What blood type will a baby have with a b negative mother and a a positive father?
B negative

no
