  1. P0: Base population for Virginia lines; BW56: 56-day body weight; σP: Sex-averaged residual phenotypic standard deviation; h2: narrow-sense heritability estimated based on realised selection-response (P0; [37]) or pedigree (F15); h2 sweeps: heritability contributed by sweeps associated with BW56 at 5/20 % FDR thresholds; σAtot: Total additive genetic standard deviation; σAsweeps: Additive genetic standard deviation due to selective sweeps associated with BW56 at 5/20 % FDR thresholds
