Among AA participants, maternal (but not paternal) transmitted and nontransmitted alleles had significant indirect effects on offspring AUDSx mediated through maternal AUDSx. Maternal nontransmitted alleles had significant indirect effects on offspring MaxDrinks through maternal MaxDrinks. There was no evidence that parental genotypes had indirect effects on offspring Initiation or Intoxication through the corresponding parental alcohol phenotypes.
