Genetic Redundancy

J. Bellay, Chad L Myers

Research output: Chapter in Book/Report/Conference proceedingChapter


Genetic redundancy stems from the observation that biological systems are often surprisingly robust to genetic perturbations. Even in the extreme case of gene deletion mutants, it appears that a minority of genes are necessary for normal cellular function. Understanding genetic redundancy is important for understanding the theory of evolution and its exact nature has been a highly debated topic. Experimental observation of genetic redundancy is itself a useful tool for discovery in biological systems.
