Gene redundancy

Figure 1. Common mechanisms of gene duplication.

Figure 2. After a duplication event, redundant genes undergo either subfunctionalization, neofunctionalization, or gene loss

Gene redundancy is the existence of multiple genes in the genome of an organism that perform the same function. 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 the knockout of a gene with only one copy.
