Yes, they can have a child with blood type AB, which is the rarest of the four types.
No - this is not possible. The child must have one parent with an A allele in order to have type A blood. Neither of these parents have an A allele - so this is not possible.
i think it can be possible but not very likeley
In that given scenario, the possible blood types of the child are: A-, A+, O+ and O-.So Yes, it is possible to have a child with A positive with 25%.
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.
O- would be the only possible blood type for the child.
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.
it is possible but the child can be a positive
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.
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. Source: http://en.wikipedia.org/wiki/Blood_type
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.
No they cannot. They can only have a child with type A or type O blood.
If both parents are blood type A, they can each carry a recessive gene for blood type O. When these recessive genes are passed on to the child from both parents, the child will have blood type O. This is a result of both parents being carriers for the O blood type gene.
