‘QTL effect’ indicates if the CB4856 genotype at the QTL increases (P) or decreases (N) the number of dauer larvae in comparison to N2. ‘QTL Limits’ denote the maximum possible QTL region defined by these comparisons. ‘Overlap’ denotes QTLs that colocalize with QTLs affecting dauer larvae development in growing populations.
