TL;DR: The results suggest that egalitarian motives affect income-altering behaviours, and may therefore be an important factor underlying the evolution of strong reciprocity and, hence, cooperation in humans.

TL;DR: This paper used the classical twin design to provide estimates of genetic and environmental influences on experimentally elicited preferences for risk and giving, and found strong prima facie evidence that these preferences are broadly heritable and their estimates suggest that genetic differences explain approximately twenty percent of individual variation.

TL;DR: The results of two independently conceived and executed studies of monozygotic and dizygotic twins suggest that humans are endowed with genetic variation that influences the decision to invest, and to reciprocate investment, in the classic trust game.

TL;DR: For instance, the authors found that genes account for a significant proportion of the variation in voter turnout in monozygotic and dizygotic twins, and they also replicated these results with data from the National Longitudinal Study of Adolescent Health and show that they extend to a broad class of acts of political participation.
