Note: ACE, the additive effect of genes (A), environmental effects that are shared among twins or siblings raised together (C), and environmental effects that are not shared among twins or siblings raised together (E); rPE, phenotype–environment correlation; rGE, gene–environment correlation; low rPE = 0.10 and moderate rPE = 0.40. Corresponding variance estimates are adjacent to the upper (0.10) and lower (0.40) triangles. Subscripts 1–5 refer to the simulated measurement occasions.
