Figure 6 in Karyotype evolution in Ronderosia grasshoppers (Orthoptera: Acrididae)

Figure 6. Ancestral range estimations for eight species of Ronderosia obtained with BioGeoBEARS for the H3 and U2 genes. Time calibration and major geological epochs indicated below the tree. Chromosome numbers indicated above the graphic. Grey squares indicate the existence of a chromosome whereas white areas represent the absence of a chromosome. Coloured squares indicate different gene locations detected by FISH; light blue (pr = proximal), blue (pc = pericentromeric), green (d = distal) and turquoise (i = interstitial). 1/5 = fusion between autosome 1 with autosome 5, X4 = neo-X (X/4 fusion), X2 = neo-X (X/2 fusion), X4* = neo-X2, Y = neo-Y, Y2/4 = neo-Y (2/4 fusion).
