Results from path analyses are summarized in Table 2. As shown in Figure 1, paternal and maternal education polygenic scores were both associated with offspring education polygenic score (β = .55, p < .001 and β = .57, p < .001 for fathers and mothers, respectively), which in turn significantly predicted offspring educational attainment (β = .23, p < .001, and β = .29, p < .001 in the father model and mother model, respectively). The indirect effects linking parental education polygenic score to offspring educational attainment via offspring education polygenic score were significant for both fathers (B = .27, 95% CI = [.226, .319]), SE = .03, β= .13) and mothers (B = .35, 95% CI = [.311, .400], SE = .03, β = .17), indicating that parental education polygenic score influenced offspring educational attainment via genetic transmission. In 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
