Yes! We each have two blood types. One we get from our mother and one from our father. The O type is recesive and only seen if both of your blood types are O. Let's say that Mom is AB+ and Dad is B+. We know that mom's two blood types are A and B. She received one of each from her parents. We know that one of Dad's blood type is B. For him to be just B he carries either a second B or an O. Carring an O without a second O would cause him to have the B blood type. So we know that baby must have gotten his A from mom and his B from dad. If dad's type was BO baby could have gotten the O which would have made him AO giving him an A blood type. The same is true with + or -. The negative is an absence of an anti body on baby's blood. Once again baby has two genes that determine this. One from mom and one from dad. If one of baby's genes is for + and the other - baby will be positive. So even though both mom and dad are positive they can each carry a -. If they both passed their - to baby he will be -.
What else can I help you with?
Can two parent with A and a parent with AB positive and have O negative baby?
No.
Can a parent with a positive and a parent with ab positive have a child with a negative blood?
rarely can be
If one parent has ab positive and one parent has o negative what type of blood will the baby have?
The baby could have almost any bloodtype except for O.
Can an A negative parent and a A positive parent have a child who is AB negative blood type?
it can be rare only
Can abneg and opos have bpos baby?
Yes, an AB negative (AB-) and an O positive (O+) individual can have a baby with a B positive (B+) blood type. The possible blood types of their child can be A, B, AB, or O, depending on the combination of alleles inherited from each parent. Since the AB parent can contribute A or B alleles, and the O parent contributes an O allele, a B blood type is possible if the child inherits a B allele from the AB parent and an O allele from the O parent. Additionally, the Rh factor from the O+ parent can result in the child being Rh positive or negative.
Can an AB negative mother and an A positive father have an o positive baby?
No. The baby must inherit one allele from each parent - therefore they must get either an A or B from the mother.
How can a child's blood type be A positive if mom is O positive and dad is AB negative?
If one parent is O positive and the other is AB negative, the child could inherit the A allele from the O positive parent and the Rh factor from the AB negative parent, resulting in the child being A positive. Each parent passes on one allele for blood type and one allele for Rh factor, so different combinations are possible.
Can a o positive and a b positive have a ab negative?
No, an O-group parent cannot have an AB-group child at all.
Can an o positive and ab positive have an a negative child?
No, an O-group parent cannot have an AB-group child at all.
Can parents who are b positive have ab positive baby?
Yes, it is possible for parents who are B positive to have an AB positive baby. This would occur if one parent is B positive with the genotype BO and the other parent is AB positive with the genotype AB. The child could inherit the A and B alleles from each parent, resulting in an AB blood type.
Can a father with o positive blood have a ab- baby?
yes. mother can be ab negative.
Can an ab negative father and o positive mother parent an o positive child?
for sure
