Common, unique and differential occurrence of genes in major phyla. Diagram shows absolute number of "all non-redundant genes from 12 genomes used" (horizontal axis) that map to a particular genome. Out of 92,320 total 8,501 gene families are found in all genomes and 52,910 are unique to a particular genome.
