a Estimated marginal means and standard errors (SE) derived from General Linear Models (GLMs) with haplotype presence/absence, gender and birth rank fitted as fixed factors and sire group fitted as a random factor. Means within a row that do not share a superscript letter are different at p < 0.05 (p < 0.05 in bold and 0.05 ≤ p < 0.10 in italics). b V-GR represents carcass fat depth over the 12th rib. c Lean-meat yield expressed as a percentage of hot carcass weight. d Total lean-meat yield is the sum of the leg, loin and shoulder lean-meat yield. e The proportion lean-meat yield of leg, loin or shoulder lean-meat is the yield of the specific area divided by the total yield expressed as a percentage.
