Genetic redundancies and their evolutionary maintenance.

Advances in experimental medicine and biology - 1 Jan 2012

Abstract excerpt

Genetic redundancy refers to the common phenomenon that deleting or mutating a gene from a genome has minimal or no impact on the phenotype or fitness of the organism because of functional compensation conferred by one or more other genes. Here I summarize studies of functional redundancies between duplicate genes and those among metabolic reactions that respectively represent genetic redundancies at the...
