Univariate ACE path diagram with covariate effects. Note: The variance components of the latent variables A, C, and E are fixed at the value 1 so that the path coefficients a, c, and e are estimated. The 1.0/0.5 covariance link between the two latent A variables represents the unequal genetic relatedness between MZ and DZ twins: for MZ twins, this covariance is fixed at 1; for DZ twins, it is fixed at 0.5. b are the phenotypic means/intercepts of the covariates
