Genetic redundancy typically relates to the duplication of an open reading frame within a genome. Genetic redundancy is often inferred when the modification or deletion of a portion of genetic material in a duplicated genome results in minimal changes in trait or organismal phenotype in reference to the nonduplicated wildtype. This invariance has been attributed to buffering mechanisms promoted by duplicates and to a number of compensatory pathways independent of the duplicate. Most duplicates are rapidly lost from genomes by mutation and drift.
