Studies on grandparental investment have revealed that mothers’ fathers are emotionally closer to their grandchildren than are fathers’ mothers. In the current study, it was hypothesized that this difference is caused by the fact that fathers’ mothers often have the potential to invest in genetically more certain kin (children through their daughters). To test this hypothesis, 787 participants rated their emotional closeness and exposure to their grandparents and indicated whether they had cousins through paternal and maternal aunts and uncles. Results indicated that participants felt closer to mothers’ fathers than fathers’ mothers only when alternate investment outlets for fathers’ mothers were available. Closeness ratings to fathers’ fathers also were reduced when they had grandchildren through their daughters. Exposure to grandparents revealed a similar pattern of findings but did not show the same sensitivity to the presence of more certain kin and did not appear to account for the closeness ratings.
