you would have to know the blood type of the parents.
Not true...if parents are O and AB...child will not be O, child will be A, B or AB.
When both father and mother contribute an A gene, their child has Type A blood. In this case, the child is "pure-bred" for the A gene. The child can only pass on an A gene to his offspring. If one parent contributes and A gene and the other contributes an O gene, the child will have A blood type, but, like his parents, he'll also have both A and O genes that he may pass along to his children. However, in 1 out of 4 instances, both parents will contribute their recessive O gene to their child. When that happens, instead of the child expressing the A blood type, he will instead express the O blood type.

You need to tell first the blood types of your parents specifying that of parent related to your grandmother in order to give approximate determination.â¥

No help to know the bloodtype of the parents because any two people of any bloodtype can have an O child. You would have to type the grandmother's blood to know her bloodtype.

While the most likely answer is "O," it is not absolutely definite.
