Types of modifications and their position within the traditional classification of variability are analyzed. Through this approach contradictory status of the classification based upon phenomenology of variability is demonstrated. Interdependency of modifications and of inherent variability permits to pose an alternative classification of variability, based upon its mechanisms. There are variability: (1) connected with storage of genetic information and with replication of its carriers (genetic material) and (2) connected with realization (expression) of genetic information. So, it follows that idea of inherent and non-inherent variability is a secondary one toward their mechanisms and are connected with the taxonomy and life cycle stages. of the biological objects under investigation.
