orthologues

Example:The orthologues of a gene in two related species often have similar functions and structures.

Definition:In biology, genes in different species that evolved from a common ancestral gene by speciation.

Example:Orthologues play a critical role in the study of homology and the evolution of gene functions.

Definition:A similarity in structure or function in different organisms resulting from their common evolutionary origin.

Example:Comparing orthologs and paralogs can provide insights into the evolutionary history of a gene family.

Definition:The evolutionary relationship between gene duplicates (paralogs) or between genes in different species (orthologs) that have originated by speciation, not by gene duplication within a species.
