Figure 2. Independent pathway multivariate model. Observed variables are depicted in squares and latent variables in circles. Ac: Additive genetic factors common to the phenotypes; Cc: shared environmental factors common to the phenotypes; Ec: unique environmental factors common to the phenotypes. A: additive genetic factors specific to the phenotypes; C: shared environmental factors specific to the phenotypes; E: unique environmental factors specific to the phenotypes.
