The phylogenetic profile method relies on detection of orthologs (or homologs, in a variation of the method) in a set of genomes.

The phylogenetic profile method relies on detection of orthologs (or homologs, in a variation of the method) in a set of genomes. Correct Answer True

If the pattern of ortholog presence or absence is the same in a group of proteins, then these proteins are clustered together as belonging to the same functional class. A method that appears to reliably predict a loose functional correlation between proteins is the phylogenetic profile method developed by Pellegrini and colleagues.
