Table 3:

Tract naming in T. castaneum and comparison to D. melanogaster, with respect to naming, fascicle entry point and number. We also listed the alternative D. castaneum nomenclature for lineages that was established using clonal labelling (M. Ito et al., 2013; Yu et al., 2013). We named those lineages not identified with ni and ambiguities with a question mark. Numbers of tracts for T. castaneum are means with standard deviation of a N=3 population.
