Figure 2: Comparative genomic analysis of R. bieti.

(a) Whole-genome synteny analysis for R. bieti and M. mulatta. Most R. bieti scaffolds (scaf1–scaf21) show high collinearity with the M. mulatta genome (chr1–chrX), except for the non-collinear regions indicated by red lines. (b) Distribution of the percentage identity of segmental duplications in the R. bieti genome. The horizontal axis represents the percentage identity, and the vertical axis represents the total length of the segmental duplications in each window of percentage identity. “Interscaffold” and “intrascaffold” correspond to segmental duplications between scaffolds and within scaffolds, respectively. (c) Gene family expansions and contractions in the R. bieti genome. The numbers on each branch correspond to the numbers of gene families that have expanded (orange) and contracted (blue). MRCA, most recent common ancestor.
