Gene commonality and genome intersection. The Venn diagrams illustrate the overlap of gene contents between genomes. The shaded areas demonstrate the difference between gene commonality (a) and genome intersection (b). Note that whereas g2 (intersection between two genomes) is a single number, for three genomes, there are three pairwise intersections, and only one of the three possibilities is indicated by the shaded area. In a, the common gene core of the three genomes is shown by the white area in the middle
