In Soviet times, genetics was persecuted, was almost banned... Today no one doubts this. School teachers explain the imaginary case to children from the words of TV presenters. And no one even knows that all this is a lie, comparable to the best examples of Goebbels' propaganda. This book tells about how the famous "case of geneticists" actually arose and what role I.V. Stalin played in this. The concept of academician T.D. Lysenko, whom liberal propagandists appointed the main antihero of Soviet science. It is proved that the dispute between "Michurins" and "geneticists" was based on completely different motives than is commonly believed today. And the "geneticists" themselves were not at all such "innocent lambs."
