Marginal effect sizes (sample R2 values) for all six causality scenarios. Causal models are, causal (C), reactive (R), independent (I), hidden variable affecting both traits (H), and no associations between genotypes and traits (Null). R2 values are shown for all replicate datasets within each causal scenario.
