Gene redundancy

Gene redundancy is the existence of several genes in the genome of an organism that perform the same role to some extent. This is the case for many sets of paralogous genes. When an individual gene in such a set is disrupted by mutation or targeted knockout, there can be little effect on phenotype as a result of gene redundancy, whereas the effect is large for double or triple gene knockouts.[1]
