CRISIS OF THE TRADITIONAL VARIABILITY CONCEPT: ON THE WAY TO A NEW PARADIGM

Abstract

The traditional concept of variability meets a lot of contradictions. These contradictions could be successfully overcome, when such variability aspects as a molecular nature of varieties, their heritability, and the factors directly determining organism phenotype, are clearly distinguished. The partition between hereditary and non-hereditary variability also needs correction since multiple intermediate phenomena are known. A more detailed classification is suggested, which reflects three autonomous aspects of heritability. This approach could be used as a basis for a new paradigm in the notion of variability.
