Fig. 3From: Estimation of AT and GC content distributions of nucleotide substitution rates in bacterial core genomesDensity plots of the posterior distributions of estimated α (blue) and β (red) for each of 35 core genomes. The red distribution represents GC→ AT mutation rates while the blue distribution AT→ GC mutation rates. Each core genome consists of at least 10 strains of a distinct species, with the exception of Brucella spp., which contains multiple species due to their close genomic similarityBack to article page
