Genome-wide association reveals QTL for growth, bone and in vivo carcass traits as assessed by computed tomography in Scottish Blackface lambs

Table 4 Regional heritability (h2w) for muscle traits, for windows of the genome that were significant at both the genome-wide (p < 0.05) and suggestive levels
