Reconstruction of the Hox gene complex evolution in the Drosophila subgenus. Genes are shown as arrows when the orientation 5′→3′ is known, and as rectangles otherwise. Hox genes are in black, Hox-related genes in gray, and non-Hox genes in white. (A) Lower Dipterans. (B) Before the radiation of the Drosophila genus. (C) Drosophila subgenus after its separation from that of the Sophophora subgenus. (D) Ancestor of the repleta group. (E) Present arrangement of Hox genes in Drosophila buzzatii (cf. Fig. 2A,D).
