Figure S2 in Large-scale snake genome analyses provide insights into vertebrate development

Figure S2. Snake genome features, related to Figure 2 (A) Evolution of chromosomes in snakes. In total, 23 proto-chromosomes of Serpentes were reconstructed using four lizards as outgroup. (B) Circos plots showing conserved synteny between the hypothesized Serpentes ancestor: Serpentes (red) and Hong Kong dwarf snake (Csep-blue). (C) Snake body lengths were significantly negatively correlated with the genome evolutionary rate (correlation coefficient = 0.50, p value = 0.011). (D) Length distribution of snake ancestor gain and lost genome segments. Length distribution of snake ancestor unique genome segments (left). Length distribution of snake ancestor lost genome segments (right).
