A grandparent DNA test calculates the likelihood of relatedness between a child and one or both grandparents. Because a child inherits exactly 50% of its genes from its biological mother and 50% from its biological father, that child shares exactly 25% of its genes with each biological grandparent. If both biological parents of the alleged father are tested and they do not possess the paternal genes between them, then they are excluded (ruled out) as the biological grandparents. When both biological parents of the alleged father possess the paternal genes between them, they are not excluded as the biological grandparents.
