Grandparent

Grandparents are the parents of a person’s own parent, whether that be a father or a mother. Every sexually-reproducing creature who is not a genetic chimera has a maximum of four genetic grandparents, eight genetic great-grandparents, sixteen genetic great-great-grandparents, etc. Rarely, such as in the case of sibling or half-sibling incest, these numbers are lower.
