Wikipedia
Gene duplication
Gene duplication (or chromosomal duplication or gene amplification) is a major mechanism through which new genetic material is generated during molecular evolution. It can be defined as any duplication of a region of DNA that contains a gene. Gene duplications can arise as products of several types of errors in DNA replication and repair machinery as well as through fortuitous capture by selfish genetic elements. Common sources of gene duplications include ectopic recombination, retrotransposition event, aneuploidy, polyploidy, and replication slippage.

Gene duplications can arise as products of several types of errors in DNA replication and repair machinery as well as through fortuitous capture by selfish genetic elements. Common sources of gene duplications include ectopic homologous recombination, retrotransposition event, aneuploidy, polyploidy, and replication slippage.

Gene Duplication
Processes occurring in various organisms by which new genes arise, i.e. the duplication of a single gene. In contiguous gene duplication, the duplicated sequence coexists within the boundaries set by the start and stop signals for protein synthesis of the original, resulting in a larger transcription product and protein at the expense of the preexisting protein. In discrete gene duplication, the duplicated sequence is outside the start and stop signals, resulting in two independent genes (GENES, DUPLICATE) and gene products. Gene duplication may result in a MULTIGENE FAMILY; supergenes or PSEUDOGENES. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
