Table 1.

Fitness of Δctb-1-bearing mtDNA in a wild-type (WT) nuclear background relative to control worms of the laboratory strain, N2, bearing WT mtDNA. (Fifteen replicates each of three N2 control and six experimental Δctb-1-bearing (1G.C–1G.U) lines were assayed. Estimates of the mean phenotype for four fitness traits are provided for the WT N2 control (${\overline{Z}}_{N2\hspace{0.17em}\mathrm{control}}$; three lines each with 15 replicates, n = 45) and the six 1G-derived, Δctb-1 bearing lines (${\overline{Z}}_{\mathrm{\Delta }ctb-\mathit{1}\hspace{0.17em}\mathrm{bearing}\hspace{0.17em}\mathrm{line}\hspace{0.17em}1\mathrm{G}}$; n = 90). Mean fitness values across n = 15 replicates for individual control and experimental lines are also provided (three N2 control and six Δctb-1-bearing lines).)
