If one parent is B positive and the other one is O positive what blood type would the child have?

We are looking for the possible blood types of a baby.
Parental information:
- Mother type B neg -- can be BB or BO and onlyRh (--)
- Father type O pos -- can only be be OO and Rh (++) or (+-)
- Baby is type BO (+-) = B pos
- Baby is type BO (--) = B neg
- Baby is type OO (+-) = O pos
- Baby is type OO (--) = O neg

∙ 14y agoEach parent contributes one blood group gene to a child, so a blood group is made up of 2 parts. If both parents contribute a "B" gene, then the blood group would most definitely be B (homozygous). However, if a parent has both a B gene and an O gene, then even though their blood group is "B" they have the potential of contributing the "O" portion to a child. "O" is always recessive. B from one parent and O from another yields "BO" or simply group B (hetreozygous). The same works for the Rh type; you could be Rh positive, but have a recessive Rh negative gene. So 2 Rh positive heterozygous parents could potentially have an Rh negative baby. The answer to the question is: There are 4 possible blood group/types: B+, B-, O+, O-

Can b positive parent have child with a positive blood?
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
What type of blood does a child make is one parent blood type is O positive a the other is a positive?
The child could be A+ or O+.
If one parent is o positive and other parent a positive what will their child be?
the child's blood type will be whatever their mother's is in almost all cases because the mother cannot host the life of a child with a different blood type. this is because the mother gives the child blood so they must be the same type.
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.
If one parent is o positive and the other is a positive what will the child's be?
The question is incomplete. The blood type, (or ABO group), for only one parent is there. Positive refers to the presence of an antigen for the Rh group . The child will therefore be Rh positive since both parents are Rh positive. One parent's blood type is O. The other parent can have O, A, B, or AB as a bloodgroup. Without knowing both parents blood groups, and not just the Rh status, there is no way of knowing the bloodtype of the child.
Can one parent have b positive blood and the other parent have a positive blood have an ab negative child together?
Yes, if the first parents' genotype is either BB+- or BO+-, and the second either AA+- or AO+-.
How can a child's blood type be A positive if mom is O positive and dad is AB negative?
because the dad blood was stronger and one positive and one negative make a positive
What blood type would a child have if one parent was b negative and the other b positive?
b posgative
If you are AB plus can your child have the same blood type as you?
The child can have the same blood type. It is possible if the child obtains the allele IA from one parent and IB from the other. So if a person with blood type AB provides IA or IB and the other parent provides the other allele, then the child may have the same blood type i.e. AB positive.
If one parent has A positive blood and the other had A positive blood what type will the baby have?
The blood type would be A positive.
A child is born with type AB blood what blood must the parents have?
The most likely blood type for the child is A positive - but A negative, O positive and O negative are also possible depending on the genotypes of the parents. If both parents are heterozygous AO, then the child could have either A or O type blood. If either parent is homozygous, AA, then the child must have blood type A. If the parent with positive blood is heterozygous, Dd (+-), then the child could have either positive or negative type blood. If they are homozygous, DD (++), then the child must have positive type blood.
Can a child have A negative if one parent is A positive and the other is B positive?
no
