Full alignments of the insect Group B protein sequences. A) SoxN. B) Dichaete. C) Sox21a, the position of the conserved intron is indicated with an arrow. D) Sox21b, the location of the exons in the D. melanogaster sequence in indicated in italics above the alignment. Black arrowheads above the alignment indicate positions of introns conserved in all four species. The grey arrowheads indicate intron positions conserved in the diptera. The black arrow above the alignment indicates the drosophila specific intron and the grey arrows below the alignment indicates the apis-specific introns.
