Chromosomal regions of pQTLs with significant genome-wide LRS values determined by single QTL scans and CIM.

Abbreviations and definitions: pQTL (chr): chromosomal position of quantitative trait locus; LRS (max): likelihood ratio statistic, maximum association between genotype and phenotype variation; SNP (max): single nucleotide polymorphism with maximum LRS in QTL region; 1.5 LOD support interval (Mb): chromosomal region in Megabases spanning QTL position; Additive allele effect: estimate of a change in the average phenotype by substitution of one parental allele by another at a given marker position; (−) values indicate an increase of phenotype by C57BL/6J allele, (+) values an increase of phenotype by DBA/2J allele; Dataset: dataset in which the QTL was identified; Hyp: hydroxyproline; CIM: composite interval mapping.
