WebDec 1, 2024 · 1. Introduction. Phenotypic robustness is the quality of a biological system to maintain its phenotype in spite of internal (e.g., genetic) or external (e.g., environmental) modifications (Wagner, 2011, Klingenberg, 2024).This quality is widespread in living systems and can be observed at different levels of biological organization, from molecules to … WebOct 14, 2015 · Abstract. Background Robustness to genetic and environmental perturbation is a salient feature of multicellular organisms. Loss of developmental robustness can lead to severe phenotypic defects and fitness loss. However, perfect robustness, i.e. no variation at all, is evolutionarily unfit as organisms must be able to change phenotype to properly … cynthia shughrue
