Fig. 2.

The association between risk allele frequency (p) and heritability coefficient (h²) at various levels of the relative risk (RR; 1.2, 1.5 or 2.0) for disease per copy of the risk allele and the baseline risk (R₀; 0.01, 0.05 or 0.10). For RR = 1.2 only R₀ = 0.10 is shown since h² is marginal when R₀ < 0.10 at this effect level
