Mutations in all five affect axon guidance, either alone or in combination. Highly penetrant central nervous system (CNS) WebFeb 6, 2009 · Genetic redundancy has long been viewed as being the fuel of evolutionary change by decoupling genotypic information from its phenotypic expression and consequently from selection. Yet, redundancy is expected to “burn out” in the process of evolutionary change. Here, we have argued that redundancy, in certain contexts, may …
