Table 1 A summary of all data for each species used in this study, including the species name and abbreviation, percentage of the genome that is heterochromatin (%HC), whether the species harbors common inversions, the mean dot-dot separation distance (in µm), the number of oocytes sampled, and the mean size of the dot chromosomes (µm). *: Data for this species taken from (Gilliland, Colwell, Osiecki, et al. 2015). n.d.: not done, as this species lacks a free dot chromosome
