When performing a DNA grandparent test the genetic markers analysed from the grandparent (s) is compared to that of the child in question. If the result indicates a biological relationship in between them, then this will in turn confirm that the biological parent of the child is the son/daughter of the grandparents due to the fact some of the genes inherited from the parent will be of course coming from the grandparents.

For example, if the child is male and the grandfather is on the market for testing, then a Y Chromosome DNA test is preferable as it will confirm that the child is from the similar male lineage with 100% certainty. This DNA test works on the basis that the Y chromosome is passed on from father to son and subsequently remains intact by way of the direct male lineage.
