Figure 4:

Fraction of heritability explained ($\frac{h_{\text{explained }}^2}{h^2}$) in West African (AFR) and East Asian (EAS) continental groups by all causal loci in Europeans. The ρ parameter is the pleiotropy parameter of the Uricchio et al. (2016) model, with low ρ representing high pleiotropy. Box plots represent the distribution of values across 10 independent simulations.
