+0.76) and females (rA = +0.52) suggests that there is substantial—but incomplete—overlap between the genes that predispose individuals to AUD and divorce. The genetic correlation between AUD and divorce is consistent with previous work showing that heritable personality factors related to behavioral undercontrol account for some of the heritability of AUD and divorce (21, 37). Furthermore, this genetic correlation is consistent with two potential interpretations: the first being that the association between AUD and divorce is attributable to non-causal genetic factors; the second being that genetic factors influence AUD, and that AUD in turn causes divorce (or vice versa). Whether this reflects non-causal and causal processes cannot be determined from a bivariate Cholesky model.
