Fig. 3From: cognac: rapid generation of concatenated gene alignments for phylogenetic inference from large, bacterial whole genome sequencing datasetsThe fraction of unique alleles per gene is inversely proportional to the number of genomes in the dataset. a The distribution of unique alleles per core gene included in the alignment as a fraction of the number of genomes. b The relationship between the number of genomes and the median fraction of unique alleles for each geneBack to article page
