|Description||In 1865, Johann Gregor Mendel presented to a scientific community the results of his 17 years lasting experiments on heredity of annual plants and theoretical interpretation of them. In that way he laid down the foundations of genetics. The basic general principles of his logical general conclusions are today, to his honour, called Mendel’s laws of heredity. Nevertheless, Mendel himself did not express them by any brief, succint and definite version – similar to other accepted, e.g. physical laws of the type of the ancient mechanical law of Archimedes. As a result, today’s Mendel’s laws have been presented by many experts – Mendel’s successors – in various generations all the world around in an increasing number of versions of various levels of success. It is the object of this communication to follow the variety of versions of Mendel’s laws in two ways: chronologically during the about 150 years since 1865 and comparing a representative sample of formulations of them in contemporary monographs and textbooks. The final aim is to try to recommend the most useful formulation from the didactic point of view.|
