(1981) Bouchard Jr. & McGue analyze 111 studies on familial resemblances in measured intelligence and reveal a profile of average correlations consistent with polygenic inheritance modes.
This means that these 111 studies (covering over 1.000.000 people) show evidence of polygenic inheritance modes.
Years after this study was performed polygenic inheritance of DNA was confirmed by genetic studies such as (Davies et al., 2011) and (Deary, Johnson & Houlihan, 2009)

(2009) Way & Lieberman analyze genetic contribution to cultural differences in this piece and draw support for dual-inheritance theory.
They show that there are genetic predispositions for IQ, collectivism, individualism, a wide breadth of aspects of socialization, depression, and other psychocultural phenomena which determine the values of societies and their people. They show that populations have mean genetics which means they have mean dispositions and thus mean personalities as well and thus cultures are formed around those same means.
