Locomotion rate, mean for 12 animals. Brood size, mean for 10 animals. Four extrachromosomal arrays (nEx) were generated, two containing lin-15(+) alone and two containing both lin-15(+) and sup-18(+), and were introduced into the different genetic backgrounds by mating to ensure consistent gene dosage among experiments. ND, not determined. LR: locomotory rate (bodybends/min).
