Duplication Definition:
When the "deleted" fragment attaches as an extra segment to a sister chromatid, it produces a duplication.

Duplication Notes:
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 are an essential source of genetic novelty that can lead to evolutionary innovation. If one copy of a gene experiences a mutation that affects its original function, the second copy can serve as a 'spare part' and continue to function correctly.
