Local gene duplication (aka tandem gene duplications) is the process by which a gene gets an additional genomic copy of itself that is located proximal. While the exact mechanism that creates the initial local duplicate is not known, once a double exists, it sets the stage for additional local duplicates to be created through nonhomologous recombination or unequal crossing-over.
