Gene duplication

Schematic of a region of a chromosome before and after a duplication event

Gene duplication (or gene amplification) is any duplication of a region of DNA that contains a gene.

Gene duplication is important in supplying raw genetic material – new genes – to biological evolution. This has been recognized since the 1930s. Recent genomic sequence data show that duplicated genes are common in all organisms surveyed.[1]
