No. A child of A and O parents would have A or O. For the child to be AB the parents would have to be A and B Or at least one would have to be AB. The O parent cannot be the parent - you might want to follow up with your doctor for further testing.

∙ 12y agousing the information given, you can assume that if they do have the same parents, one must havethe genotype iAiO and the other must have the genotype iBiO. if you do a simple punnet square, you will see that it there is a 1:1:1:1 ratio, with one being iAiO, one being iBiO, one being iAiB, and one being iOiO. the fact that they are both positive means that they both have antibodies, which is inherited through one parent, so the siblings can have the same parent.

∙ 11y agoNo. The A blood group is either homozygous AA or heterozygous AO. Neither parent has a B allele, so their child cannot have the AB blood group.

No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
If both parents have positive blood type will the child have a positive?
Probably, because it only takes one positive gene to have positive type blood. But if the positive parents each have one positive and one negative gene, there is a 25% chance their child will be negative.
Can negative and a positive blood type make a positive?
If one of the parents is A positive, the child could be A positive.
Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.

it is possible but the child can be a positive
Can a child have a negative blood types if the parents are both a positive?
Yes! Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
Can a child with o negative blood have the same parents as a child with o positive blood?
yes
Can two parents with A positive blood have a child with O negative blood type?
No.
Can a b positive and a positive have a b negative child?

If both parents are B- they can only have children who are B- and O-. One would have to be positive in order to have a child with positive blood.
If both parents have positive blood type will the child have a positive?
Probably, because it only takes one positive gene to have positive type blood. But if the positive parents each have one positive and one negative gene, there is a 25% chance their child will be negative.
