Title Parent - offspring conflict in Japan and parental influence across six cultures
Previous research has demonstrated that parents and children often have conflicting mate preferences. The present research was conducted among 443 Japanese university students. Using an existing scale designed to uncover parent-offspring conflict over mate choice, the results revealed that children perceived having a potential partner with traits connoting poor genetic quality as being more una...
متن کاملEvolutionary conflicts of interest: are female sexual decisions different?
Analyses of reproductive conflicts of interests have yielded important evolutionary insights in many areas of biology. The usefulness of conflict analyses of traits that have been traditionally interpreted as resulting from female choice is controversial, however. This article explores a possible explanation for why conflicts of interest may be ameliorated in female choice situations. In contra...
متن کاملMothers Do Not Show Increased Offspring Avoidance and Elevated Corticosterone Levels during Weaning Conflict in Rats
Parent-offspring conflict is predicted to occur because offspring will demand more parental investment than is optimal for the parent, and is said to be strongest during weaning when parents reduce nursing while offspring continue to demand parental care. While weaning conflict has been shown to be stressful in offspring, little is known about the effects of weaning conflict on mothers. We hypo...
متن کاملA theoretical model of the evolution of maternal effects under parent-offspring conflict.
The evolution of maternal effects on offspring phenotype should depend on the extent of parent-offspring conflict and costs and constraints associated with maternal and offspring strategies. Here, we develop a model of maternal effects on offspring dispersal phenotype under parent-offspring conflict to evaluate such dependence. In the absence of evolutionary constraints and costs, offspring evo...
متن کاملMedical, ethical and personal dimensions of parent–offspring conflicts
Among the most fundamental and intimate of human reproductive processes are fetal development and infant care. As first described by Haig [1], genetic conflicts centrally mediate such maternal–offspring interactions, and risks for a broad swath of major medical conditions, including preeclampsia, gestational diabetes and intrauterine growth restriction, appear to substantially involve dysregula...
متن کاملParent-offspring conflict and co-adaptation: behavioural ecology meets quantitative genetics.
The evolution of the complex and dynamic behavioural interactions between caring parents and their dependent offspring is a major area of research in behavioural ecology and quantitative genetics. While behavioural ecologists examine the evolution of interactions between parents and offspring in the light of parent-offspring conflict and its resolution, quantitative geneticists explore the evol...
