ortholog

« Back to Glossary Index

Used to refer to homologous genes or proteins, that originate from one and the same gene present in the last common ancestor of the species under consideration. Frequently (but not always), orthologous proteins have the same function in the different species and the corresponding genes are considered as “the same genes in different species”. Not to be confused with “paralog”.
