Results from QTL mapping on the complete data set using the Haley-Knott method on the trait Test-Period Survival.

Data set	Body weight as covariate	QTL position (cM)	LRT
Restricteda	Yes	32	65.9*
Restricteda	No	32	67.5*
Completeb	Yes	32	71.9*
Completeb	No	32	74.7**

The significance levels of the Likelihood Ratio Test (LRT) statistic were computed by permutation testing.

*P < 0.05

**P < 0.01

^aAll families that were genotyped, except those that were used in the initial genome scan [12]
