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 .
Evolution by gene duplication is an event by which a gene or part of a gene can have two identical copies that can not be distinguished from each other. This phenomenon is understood to be an important source of novelty in evolution, providing for an expanded repertoire of molecular activities.
The 2R hypothesis or Ohno's hypothesis, first proposed by Susumu Ohno in 1970, [1] is a hypothesis that the genomes of the early vertebrate lineage underwent two whole genome duplications, and thus modern vertebrate genomes reflect paleopolyploidy.

The company, operated under the Ministry of Transport of Vietnam , was founded on January 8, 2012 when three companies operating airports in the north ...
[6] [7] [8] Gene redundancy has long been appreciated as a source of novel gene origination; [8] that is, new genes may arise when selective pressure exists on the duplicate, while the original gene is maintained to perform the original function, as proposed by newer models [4]. Figure 1. Common mechanisms of gene duplication.
FPT, officially the FPT Corporation (Vietnamese: Công ty Cổ phần FPT, lit. 'FPT Joint Stock Company'; "FPT" stands for Financing and Promoting Technology), is the largest information technology service company in Vietnam with operations spanning three fundamental sectors: Technology, Telecommunications and Education.
