Figure 1From: An improved method for identifying functionally linked proteins using phylogenetic profilesPhylogenetic profiles. We show hypothetical phylogenetic profiles for four genes. Genes 1 and 2 have four common 1's ("matches") in three runs while genes 3 and 4 have four matches in a single run. We hypothesize that genes 1 and 2 are more likely to be truly co-evolving while genes 3 and 4 are likely to be just lineage-specific.Back to article page
