| Research Abstract |
The grandmother hypothesis is a theory that posits that female post-reproductive life has been prolonged as it helps increase reproductive success of their adult children. In our studies, however, the parent whose presence exerted positive effects on the reproduction of daughters(earlier birth of the first child and shorter inter-birth interval between the first and second children), was the mother-in-law(husband's mother). The implication of the findings is that, in a traditionally patrilocal country such as Japan, the relationship between mother-and daughter-in-law influences the reproductive success more than the relationship between biological mother-and daughter. It is thus necessary to take cultural context into consideration when testing the grandmother hypothesis in modern society.
