^aLine B proportions are estimated from estimated breed-origin-of-alleles (BOA), using linear regression on mean allele counts within line (LR), ADMIXTURE analysis (ADM), the genomic relationship with maternal grandsire (REL_GP), or this relationship after adjusting all self-relationships to 1 (REL_GP_noF)
