Genetics grew into a scientific discipline during the first decade of the twentieth century, it prospered and became acknowledged in its first half, it widened into the molecular field during its second half. This expansion attracted scientists from nearby branches such as biochemistry, biophysics, cell biology, statistics and computer science, which started to call themselves geneticists without deeper insights into the classical genetics. They may be unaware of how far the science had advanced already before the molecular window was opened. Then, what is the essence of genetics? It is involved in all aspects of biology, and has branched into different disciplines, rather far apart. Still it is held together by its core, the evolutionary coalescence of all living organisms on earth and their surprisingly great conformity in physiological and hereditary mechanisms. In the early definitions before the year 1900 the word variation is often included, most bluntly as the science of variation. Similarities and differences between parent and offspring are also emphasised. Inheritance causes similarities but not complete likeness. The name of the subject, genetics, was introduced by W. Bateson in 1906 and defined as the scientific study of the heredity of individuals. Later definitions have become more extensive and include not only the transmission of the hereditary factors but also their nature and the way in which they influence the living organism at different stages and at different levels, from molecules to populations and ecosystems.
