Graph illustrating the pairwise corrected distances between arthropod orthologous genes and between Crmar2 and Mariner - 5 consensus sequences. Orthologous gene distances between A. vulgare and D. melanogaster, between D. melanogaster and C. capitata, and between H. saltator and D. melanogaster are illustrated with blue lozenges, red squares, and green triangles, respectively. Other symbols correspond to transposable element (TE) distances: Mariner-5 between H. saltator and D. biarmipes (filled black lozenge), Crmar2 between C. rosa and D. bipectinata (empty black lozenge), Mariner-5 between A. vulgare and D. biarmipes (filled purple lozenge), Crmar2 between A. vulgare and C. rosa (empty purple lozenge), and Crmar2 between A. vulgare and D. bipectinata (filled green lozenge). A detailed list of genes and distances is provided in Additional file 8: Table S3. Before the distance values were plotted, they were sorted by ascending order.
