Fig. 6

TEM images representing variability of observations between eggs from good and poor quality batches. Despite standard treatment of biological samples, a high variability in morphology was sometimes observed between eggs from the same batch. Panel A represents an egg containing a high number of well-formed mitochondria while Panel B represents an egg containing a high number of completely deformed mitochondria. Both eggs belonged to the same good quality batch and were kept in the same tube during fixation and postfixation. Panels C and D represent eggs containing variable numbers of better-shaped mitochondria. Both eggs belonging to the same poor quality batch and were similarly kept within the same tube during fixation and postfixation. All images depicted in this figure were generated by the authors for use in this article. Scale bars indicate 1 μm at 8 K magnification
