Gene duplication (or chromosomal duplication or gene amplification) is a major mechanism through which new genetic material is generated during molecular...

A gene family is a set of several similar genes, formed by duplication of a single original gene, and generally with similar biochemical functions. One...

can result from gene duplication. Such duplication events are responsible for many sets of paralogous genes. When an individual gene in such a set is disrupted...

duplication of genes within the same chromosome whereas trans duplication, or interchromosomal duplication, consists of duplicating genes on neighboring...

functional divergence that occurs after a gene duplication event, in which pairs of genes that originate from duplication, or paralogs, take on separate functions...

either a speciation event (orthologs), or a duplication event (paralogs), or else a horizontal (or lateral) gene transfer event (xenologs). Homology among...

gene duplication events, the following rules are often applied: Duplicated genes are located in large duplicated blocks. Single gene duplication is a...

forms of gene duplication. The product of whole-gene duplication is two copies of the gene, whereas that of diploid-type gene duplication is one gene that...

functional divergence, occurs when one gene copy, or paralog, takes on a totally new function after a gene duplication event. Neofunctionalization is an adaptive...

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...

crossing over is a type of gene duplication or deletion event that deletes a sequence in one strand and replaces it with a duplication from its sister chromatid...

N-terminus/C-terminals. TIM barrels appear to have evolved through gene duplication and domain fusion events of half-barrel proteins, with a majority of...

million years after the gene duplication, provided the gene has not been subjected to any selection pressure. Gene duplication generates functional redundancy...

1996. Ohno postulated that gene duplication plays a major role in evolution in his classic book Evolution by Gene Duplication (1970). While subsequent research...
