From: Exclusivity offers a sound yet practical species criterion for bacteria despite abundant gene flow
Exclusivity is unlikely to be the result of subsampling Streptomycetaceae genomes. Black lines show average measures of exclusivity for all clades on the pan-genome UPGMA tree for Streptomycetaceae, with ± one standard deviation indicated by the surrounding gray region. Clades are considered exclusive if their exclusivity score determined from the core-genome is greater than zero. Except for very small subsamples, exclusivity quickly plateaus with increasing sample size, suggesting that the existence of exclusivity is not the result of subsampling the total population of genomes
