They have codominance.

How do you get AB blood type?
AB blood type is inherited when a person receives one A allele and one B allele from their parents. This combination results in the AB blood type, which is the rarest blood type.
What would be the possible blood group of a child if one of his parent has blood group AB and other has O?
The child could have either blood group A or B, but not AB or O. Each parent contributes one blood type allele, so the child could inherit an A allele from one parent and a B allele from the other, resulting in blood group AB. Alternatively, the child could inherit an A allele from one parent and an O allele from the other, resulting in blood group A, or a B allele from one parent and an O allele from the other, resulting in blood group B.
If someone cross a purebred mother with type B blood and a father with type AB blood what are the possible blood type outcomes of their offspring?
The possible blood type outcomes of their offspring would be type B or AB. Each parent passes on one blood type allele to their child, so the child could inherit the B allele from the mother and the B or A allele from the father, resulting in blood type B or AB.
Can a man with blood type b and a woman with blood type ab have a child with blood type b?
Yes, a man with blood type B and a woman with blood type AB can have a child with blood type B. The child would inherit one allele for blood type B from the father and either an A or B allele from the mother. The child's blood type could be either B or AB.
How can a child that is born with type AB blood?
the child takes the A gene from one parent and B from the other. And the both of parent are supposed to be AB blood type, or one A blood type and the other B.
Can parents who are B negative and O positive have a AB positive child?
No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.
Can a woman with B blood and a man with AB blood have a child with O BLOOD?
No - this is not possible. The child must inherit one allele from each parent. This means that at least one parent must have a B allele in order for the child to have B-type blood. The only possibilities with B- X AB are B, A or AB.
Can Mother B positive Father is AB positive Can child be o negative?
A blood type O child would be impossible from this match. An AB parent must give an A allele or a B allele, and both alleles are dominant. If mother is homozygous B (meaning both alleles are B's), and father is AB, child can be either B or AB. If mother is heteroygous B (meaning one B allele and one O allele), and father is AB, the child can be either A, B, or AB.
Can mother AB negative Father is B positive can child be O negative?
A blood type O child would be impossible from this match. An AB parent must give an A allele or a B allele, and both alleles are dominant. If mother is homozygous B (meaning both alleles are B's), and father is AB, child can be either B or AB. If mother is heteroygous B (meaning one B allele and one O allele), and father is AB, the child can be either A, B, or AB.
Can parents who are AB negative and O negative have a B positive child?
Yes, if the AB parent contributes a B allele, and the O parent contributes an O allele, then the child will be BO, and will have type B blood.
Is AB blood type co-dominate alleles?
yes, that is exactly what AB blood is and that is how blood type is inherited. Nice work
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.
