TIP

To guess gene functions "by tradition" we recover gene families by their ancestry, and collate known biological roles of the family members.

TIP

The more closely related the species, the more finely-resolved the gene orthologies.

WARNING

We refer as orthologs to all descendants of a particular single gene of the last common ancestor, thus our operational definition refers to a specific phylogeny radiation for a set of species, termed the level-of-orthology.

DANGER

Note: notions of orthologs and paralogs are disjoint, e.g. paralogs can be co-orthologs if duplicated after the speciation or can be not if duplicated earlier.
