Table 3 Estimates of inbreeding depression for meat quality traits. Estimates expressed as change in adjusted phenotype per 1 % increase, using a inbreeding coefficient derived from a genomic relationship matrix (FGRM), and a inbreeding coefficient derived from runs of homozygosity (FROH)

From: Genomic structure and marker-derived gene networks for growth and meat quality traits of Brazilian Nelore beef cattle
