Shown is the difference in dauer larvae number between the IL and N2 from that assay, or between two ILs, for two re-tests of ILs with introgressions on the X chromosome for the number of dauer larvae at food exhaustion (data from [28]), two assays for the number of dauer larvae at food exhaustion, and an assay of dauer larvae numbers a week after food exhaustion (see Figure 2). Values in bold are significantly different (post hoc comparison by Mann-Whitney U-test, p<0.05) in the relevant comparison (N2 vs IL or IL vs IL). ‘QTL effect’ indicates if the initial genome-wide screen identified the QTL as positive or negative, ‘Same sign’ shows if the difference is in the same direction in all tests at food exhaustion. ‘Support’ indicates in the assay of dauer larvae numbers a week after food exhaustion identified a QTL with the same effect as the original screen. Note that QTLs gp1 and 17 are detected in Figure 1.
