^†Each line shows the correlation between two spans. RS, self-fertile reproductive span; MS, fast body movement span; FPS, fast pharyngeal pumping span; PS, pharyngeal pumping span; LS, lifespan.

^‡Mutant alleles and the number of animals analyzed are shown in Table 1. Interstrain values were derived by using the mean of the six populations. Values were determined by using Spearman rank correlation. *, P < 0.05; **, P < 0.005.

^§FPS was not determined for eat-2 mutants because they typically do not display fast pharyngeal pumping.
