Table 1 presents descriptive statistics and bivariate correlations between the key study variables. Maternal and paternal education polygenic scores were positively correlated with each other (indicative of assortative mating) and positively correlated with offspring education polygenic score and educational attainment. Maternal and paternal educational attainment and income were moderately and positively correlated with offspring educational attainment. Maternal educational attainment and mother-reported household income were positively correlated with maternal bonding, but paternal educational attainment and father-reported household income were not significantly correlated with paternal bonding.
