overlap with the genetic influences on the Internalizing spectrum. (Shared environmental factors (C) are not a substantial contributor to the etiology of Marital Quality, so the rC correlations of 1.0 are not useful to interpret, as they represent correlations between trivial variance components. These are presented simply for the sake of completeness). The non-shared environmental correlation between Marital Quality and Internalizing was −.02; thus, even though unique environmental influences weigh heavily in the etiology of both Marital Quality and Internalizing, the environmental influences important for each phenotype do not overlap.
