Fig. 2

Presence and absence of gene duplicates across 22 species of Drosophila is shown. Summary of nuclear transport genes duplication events across the Drosophila species is shown in the phylogeny. Each rectangle represents a duplication event. Duplication events are shown at an approximate distance from the tips based on the percent identity to the parental gene protein in that species (Supplementary material 4). DNA-mediated duplications are shown in bold in the table and with striped boxes in the phylogeny
