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...

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

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...

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...

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

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

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

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...
