Gene family

- Homolog

: homology between protein or DNA sequences is defined in terms of shared ancestry

 

- Ortholog

: Orthologs, or orthologous genes, are genes in different species that originated by vertical descent from a single gene of the last common ancestor.

 

- Paralog

: if a gene in an organism is duplicated to occupy two different positions in the same genome, then the two copies are paralogous.
