1Chr = chromosome

2Position in Haldane cM

3LC = QTL declared as line-cross type; HS = half-sib type; CB = combined type.

4Negative logarithm of the comparison-wise p value of the test statistic against the null hypothesis of no QTL at the most likely position for the inferred QTL model.

5FDR = false discovery rate

6Estimates of additive effects with standard errors for LC QTL. The effects are expressed as (DD-PP)/2, where D = Duroc allele and P = Pietrain allele.

7Estimates of dominance effects with standard errors for LC QTL. The effects are expressed as DP-PD, where D = Duroc allele and P = Pietrain allele.

New QTL detected with the line-cross model in the second scan.
