or par·a·logue  (păr′ə-lôg′, -lŏg′)
A gene that is related to another gene in the same organism by descent from a single ancestral gene that was duplicated and that may have a different DNA sequence and biological function.

[Back-formation from paralogous : para- (in reference to the parallel descent of the two genes from a single ancestral gene) + (homo)logous.]

pa·ral′o·gous (pə-răl′ə-gəs) adj.


either of a pair of genes derived from the same ancestral gene

Vital peptides by convention display high degree of conservation in evolutionary timeframe , therefore presents them selves as an important tool for the assessment of significant events such as genome duplication, gene paralogue formation etc in the evolutionary history of the peptide.
It has been estimated that only 50% of the duplicated genes have subsequently been lost from the genome [10] with retained paralogues able to undergo subfunctionalisation leading to altered expression [92].
Plant conserved non-coding sequences and paralogue evolution.
A paralogue is the gene that has the closest DNA sequence to another gene, probably because the two arise via gene duplication.

Inferring evolutionary relationships among members of gene families is generally problematic because distinguishing paralogues and orthologues is difficult without appropriate known outgroups to polarize the gene phylogeny.
