Fig. 1From: Whole-genome sequencing of wild Siberian musk deer (Moschus moschiferus) provides insights into its genetic featuresa The Venn diagram shows the number of orthologs shared among musk deer and other representative mammals. b Phylogeny and gene family size evolution. The phylogenetic tree is constructed based on four-fold degeneration sites among single-copy orthologs with the neighbor-joining method. The timelines indicate inferred divergence times among the species based on the molecular clock. The number of significantly expanded (red) and contracted (blue) gene families (branch-specific p-value < 0.01) are shown at each branchBack to article page
