Imre Festetics
Count Imre Festetics de Tolna (1764 – 1847) was a noble landowner and geneticist. Scientific works. Many of the central principles the discipline of genetics were formulated by Imre Festetics through the study of sheep. Festetics formulated a number of rules of heredity and was the first to refer to these as "genetic laws of nature" ("Die genetischen Gesetze der Natur"). In so doing he used the term "genetic" for the first time, 80 years before William Bateson did so in his personal letter to Adam Sedgwick. Festetics created this new term to clearly distinguish his rules of heredity , or "genetic laws," from the "physiological laws" of Ehrenfels. Genetic Laws of Nature. In these ‘‘Genetic Laws,’’ Festetics was the first to recognize empirically the segregation of characters in the second hybrid generation. He also linked heredity ("vererbung") with health and vigor independently of external factors, stressing the role of inbreeding (combined with strong selection) in stabilizing character inheritance for preserving or developing new races. To illustrate the concept he used sheep, chicken, cattle and horse breeds as examples, although he also applied it to the human species by considering populations of isolated Hungarian villages, in which he had observed  degenerative mental and physical characteristics. Festetics’s observations highlighted important correlations between variability, adaptation, and development. He also noted the consequences of selection and its role in heredity, believing that variability and his postulated laws of genetics were connected, acting together in breeding as well as in the natural processes controlling populations of different animals, including humans. Festetics, however, was ultimately hindered by the complex nature of his study traits, aspects of wool quality that we now know to be polygenic. When Gregor Mendel turned his attention to inheritance in peas he was just the latest in a line of  Moravian researchers and agriculturalists who had been thinking about inheritance, and many of the principles had already been sketched out by Festetics
