Overview of the assembly characteristics of the Visayan warty pig genome. (a) Circular diagram depicting the characteristics of the Visayan warty pig genome. The tracks from outer to inner circles are indicated in the legend (density of coding gene are shown in track 4). (b) Divergence times and history of orthologous gene families. Numbers on the nodes represent divergence times, with the error range shown in blue bar. The numbers of gene families that expanded (red) or contracted (green) in each lineage after speciation are shown on the corresponding branch. (c) Whole-genome alignment between Visayan warty pig and Duroc pig (Sscrofa11.1).
