addition, results indicated that both paternal (β = .16, p < .001) and maternal education polygenic score (β = .07, p < .001) were associated with offspring educational attainment above and beyond the effect of offspring education polygenic score, providing evidence for social genetic effects on educational attainment. In this model, 44.9% of the effect of paternal education polygenic score on offspring educational attainment was mediated by offspring education polygenic score; 71.7% of the effect of maternal education polygenic score on offspring educational attainment was mediated by offspring education polygenic score.
