Estimated mixture models. Graphical display of binomial mixture models. Each rectangle corresponds to a component, its width indicates its mixing proportion and its color indicates its detection probability (see color bar). Red areas indicate parts of the pan-genome with a small detection probability, i.e. rarely occurring genes, whilst regions towards the blue end of the scale represent conserved genes – that is, genes shared by most of the genomes.
