[i] Trait acronyms are given below Table 3. For leptin and IFG-I, logarithmic transformed data were used for the analysis. Thus, the estimates are given as logarithmic units as well.
[ii] The chromosome specific 1%, 5%, and 10% F-value thresholds estimated via permutation analyses.
[iii] The most likely locations are given as distance from the centromere.
[iv] At loci in which QTL effects were sex specific (P < 0.05), below the joint estimate over both sexes estimates are given separately for males and females.
[v] F values for traits in which two QTLs were found in a linkage group (P < 0.05); the presented F values result from one QTL analysis after fitting the second QTL on the chromosome as the background genetic effect.
[vi] The QTL effects are given as reduction of the residual sum of squares fitting 1 vs. 0 QTLs.
[vii] Males.
[viii] Females.
[ix] Symbols were given for QTLs of the genome-wide 5% significant level at F > 7.07 for loci in which two QTLs were found in a linkage group at P < 0.05 and both single QTLs have chromosome-wide significant level at P < 0.05 and for suggestive QTLs, which have been confirmed from our previous experiment (Brockmann et al. 1998). Bold printed names indicate QTL symbols that have been assigned in this study.
