At the estates of the Festetics family register records were kept at a very early time, in the first half of the nineteenth century. It is also possible that the owners of the estate researched inheritance. Between 1807 and 1828 scientific work on sheep rearing had been done at the Festetics estate. Imre Festetics published his results on natural genetic laws in Brünn in 1819. He recognized the most important laws of inheritance before Gregor Mendel.
