To guess gene functions "by tradition" we recover gene families by their ancestry, and collate known biological roles of the family members.
The more closely related the species, the more finely-resolved the gene orthologies.
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.
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.
