The density colors reflect the count of combinations giving rise to a certain number of specific genes (y-axis) in one genome compared to n - 1 other genomes; that is, for = 2, genome number 2 is compared to genome number 1 and, on average, approximately 650 genes are found to be specific to strain 2. The blue line is the fit to the originally suggested exponential decay function [3]
