Figure 4. Mitonuclear hybrid strains more often resemble their mitochondrial parental isolate.

Averages of maximum pharyngeal bulb fluorescence for mitochondrial (PB800 and HK105) and nuclear (AF16) parent isolates are on either side of the two hybrid strains (AFPB800 and AFHK105) (Fig. 1). Letters denote significantly different groups as determined by Tukey HSD analysis. Bars show one SEM for 15–20 independent samples.
