Power and FDR estimates for GWA mappings performed with subsampled populations of increasing depth.

Sample size	Power	FDR
100	0.27 ± 0.13	0.63 ± 0.27
200	0.32 ± 0.14	0.49 ± 0.30
300	0.36 ± 0.16	0.38 ± 0.29
400	0.38 ± 0.16	0.31 ± 0.28
500	0.41 ± 0.17	0.27 ± 0.26

Traits were simulated with a heritability of 0.8 and 5 underlying QTL effects sampled from Gamma (k = 0.4, θ  = 1.66).
