We are looking for the possible blood types of a baby.
Parental information:
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.
yes they can
most probably not.
No.
Yes, they can have a child with blood type AB, which is the rarest of the four types.
Yes this could happen if the geno-type of both parents is heterozygous, what i mean by that is to have this symbol for both parents : IAi X IAi so to have a child with type O, the possibility for that is 25%
Yes, if both parents have the genotype AO, then the child can have the O from both parents, phenotype O
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+.
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.
Not at all.
Yes. The geneotype for both parents must be AO+- for the child to be OO--
Parents must be blood type A or O. Any other blood type will not result in a sole A type child. It might result in several other combinations though, which are not relevant to this question.
