Genomic (A) and phylogenetic (B) localization of the three Hox gene complex splits observed in the Drosophila genus. (A) Ancestral arrangement of the eight Hox genes within the insects is as follows: labial (lab), proboscipedia (pb), Deformed (Dfd), Sex combs reduced (Scr), Antennapedia (Antp), Ultrabithorax (Ubx), abdominal A (abdA), and Abdominal B (AbdB). (B) Phylogenetic relationships and divergence times for the five Drosophila species included in this study. D. melanogaster and D. pseudoobscura belong to the Sophophora subgenus. D. repleta and D. buzzatii (both in the repleta species group) and D. virilis (virilis species group) belong to the Drosophila subgenus (see Negre et al. 2003 for details).
