^aCIII population contains introgressed CLPG allele from Dorset into terminal sire composite population (1/2 Columbia; 1/4 Suffolk; 1/4 Hampshire). The new composite population is on average 1/16 Dorset germplasm. 

^bGenotype at CLPG locus with C representing the mutant allele, N the normal allele; the paternally-derived allele is listed first. 

^cMultiple sequence reads contributed data for each animal-SNP combination. 

^dHeterozygosity per base pair over the covered region of 209,580.
