Definition of Homolog, Ortholog and Paralog. It was suggested that I might want to provide definitions which made the difference between these terms clear. These definitions are provided here. Homolog. A gene related to a second gene by descent from a common ancestral DNA sequence. The term, homolog, may apply to the relationship between genes separated by the event of speciation (see ortholog) or to the relationship betwen genes separated by the event of genetic duplication (see paralog). Orthologs are genes in different species that evolved from a common ancestral gene by speciation.
