From: VBCG: 20 validated bacterial core genes for phylogenomic analysis with high fidelity and resolution
The presence and single-copy ratios of the candidate core genes in the Kingdom Bacteria. In the total core genes (A), the 47 ribosomal proteins had much higher ubiquity (median presence ratios: 98.9%) and uniqueness (median single-copy ratios: 98.7%) than those of the other core genes (95.7% and 94.2%). The dashed line demarcates the 95% ratio. In total 85 core genes (B) with both presence and single-copy ratios > 95% were retained for the fidelity and resolution tests
