Table 2 summarizes the indirect effects of transmitted and nontransmitted paternal and maternal alleles on offspring alcohol outcomes via parental relationship discord and divorce for each ancestry group, separately. These effects correspond to paths Tp.Yd × Yd.Yo, NTp.Yd × Yd.Yo, Tm.Ym × Ym.Yd, NTm.Yd × Yd.Yo in Figure 1. Among EA participants, there was evidence that nontransmitted paternal and transmitted maternal alleles had indirect genetic effects on offspring AUDSx, MaxDrinks, Initiation, and Intoxication through parental relationship discord. Nontransmitted paternal and nontransmitted maternal alleles had indirect effects on offspring Initiation and Intoxication through parental divorce.
