I assume the question is "Is it possible for two parents with type B blood to have a child with type O blood?"

Yes they can, if both parents have BO genotype. The chance of the child having O blood is 25% in this case.

Is it possible for 2 parents with type b blood to have a child with Type 0 blood?

Yes, they can have a child with blood type AB, which is the rarest of the four types.


How can two parents with blood type O negative have a child with blood type AB?

It is not possible for two parents with blood type O negative to have a child with blood type AB. In the ABO blood group system, type O is recessive and AB is a combination of A and B, making it impossible for two parents with type O blood to produce a child with type AB blood.


What some have o blood type where both parents are AB and B?

It is not possible for two parents with blood types AB and B to have a child with O blood type. A child's blood type is determined by the combination of their parents' genes, and O blood type requires both parents to have at least one O gene.


Can two parents with o positive have a child with a A negative blood type?

it is possible but the child can be a positive


Is it possible for parents who are both blood group O to have babies who are blood group A?

Yes, it is possible for two parents who are both blood group O to have a child who is blood group A. This can occur if both parents carry the A allele in their genes, even though their own blood types are O.


How could a child have A blood type when parents are both o plus?

It's not possible for two O+ parents to have a child with A blood type. A child's blood type is determined by the combination of genes inherited from the parents, and in this case, the genetic combination would result in the child also having O+ blood type. A possible explanation could be an error in blood typing or paternity.


If both parents are blood type o is it possible for their child to have a blood type a positive?

No, two type O parents can only have type O children. See the table below from www.dna-bioscience.co.uk/did_you_know_abo.shtml If you look at the row for mother's blood type O where it intersects with the column for father's blood type O, you will see that the child's blood type must be O. For the child to be Rh+, only one of the parents has to be Rh+.


What are the two possible genotypes for blood type A?

The two possible genotypes for blood type A are AA and AO.


Is there a posibility to have a child that is blood type -A A couple who are blood type B and blood type O?

No. It is not possible for a child to have A if the parents are O blood type. If both parents have type O blood, then their children will also have type O blood. However, two parents with type A or type B blood (both the same or one of each) can sometimes have a child with type O blood. That is because the gene for type O blood is recessive. But they must carry the O type. However, two parents with type AB blood can have a child with type A, type B, or type AB blood, but cannot have a child with type O blood.


Possible blood types of offspring?

Offspring can inherit blood type from their parents based on their genotypes. Possible blood types include A, B, AB, and O. A child's blood type will be determined by the combination of blood type alleles inherited from their parents.


Can parents both blood type O positive have a child with ab positive blood?

Generally no but in very rare circumstances, through mutations and incorrectly copying DNA, it is possible for two parents with type O blood to have a child with AB blood.


Can a parent with ab plus and the other parent with o plus have a child with o plus?

Yes, it is possible for two parents, one with AB+ blood type and the other with O+ blood type, to have a child with O+ blood type. When two parents with different blood types have a child, the child's blood type can be a combination of the parents' blood types through genetic inheritance.
