Duplication mutations result in the selective increase of genes within a localized region of a chromosome. At the chromosomal level, duplication mutations are one of four structural alterations that occur during the duplication (replication) of...

Gene duplication (or chromosomal duplication) is any duplication of a region of DNA that contains a gene; it may occur as an error in homologous recombination, a retrotransposition event, or duplication of an entire chromosome. [1]. The second copy of...

Two major evolutionary mechanisms, probably acting in concert, are believed to be responsible for creating new functional genetic information. These mechanisms are symbiosis and gene duplication. Symbiosis, when two or more organisms coexist in close proximity, can lead to a codependence such that...

The November 2001 issue of The Plant Cell includes a letter to the editor from Sheng Luan and colleagues regarding the renaming of genes and duplication of gene names in the literature. Plant Physiology joins with The Plant Cell in recognizing gene nomenclature as...
