Yes, they can have a child with blood type AB, which is the rarest of the four types.
Yes
but the reverse is not possible for two parents with type O to have a type B child
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%.
O- would be the only possible blood type for the child.
it is possible but the child can be a positive
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
Only B and O are possible
No. As long as one parent has an A allele (blood type AB or A) and the other has an i allele (blood type O, A* or B*), it is possible to have a type A child. (* means that the types have to be heterozygous)
It is possible if your parents have different blood types. Example, if your father is A with a recessive O, and mother is B with a recessive O, you could easily land up with a O blood group. However, an AB father can have only an A, B or AB child depending on the mothers blood group, but surely NOT 'O.'
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.
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.
Yes the child can have a very different blood type than the parents
