Phylogenetic relationships among Sxl genes from dipteran species. Bootstrap values (BP, boldface type) and interior branch test values (CP, regular type) are provided at the corresponding nodes. (A) Minimum-evolution tree reconstructed from complete nucleotide-coding sequences using Kimura's two-parameter distances; (B) the minimum-evolution tree reconstructed using modified Nei-Gojobori distances (p_S). All nodes are significantly supported by BS and CP values in both phylogenies, except in the Sciaridae where the node was collapsed. Tree topologies gather together members of the same families and fit the taxonomic classification of these dipteran species.
