title: [A new stage in the development of genetics and term "epigenetics"].
abstract: Genetics requires verification of the notion of gene. In this article, DNA and DNA parts are proposed to be named progenes, while the term gene refers to the informational products produced on DNA. These are RNA genes, protein genes, and DNA genes (transposable elements). The focus of genetics is thus switched from characters of intraspecies difference to characters of intraspecies similarity. Regulatory genes controlling ontogeny (ontogenes) become the main object of research. These genes can be isolated by methods of both reverse and direct genetics. The properties of ontogene mutations, produced by methods of direct genetics, are described. The problematic of epigenetics is related to the expression of ontogenes. The term epigenetics is not correct because of its ambiguity.
