Continuing the topic of protecting the honor of the outstanding Russian scientist T. D. Lysenko, the author wondered what classical or formal genetics is studying now, and found out that at present the scope of its application has been reduced to a vanishingly small value. It degenerated into something similar to the hypothesis of a heat or phlogiston. In fact, formal genetics secretly, quietly and imperceptibly turned out to be replaced by cellular and molecular biology. The author proves that now, as a science, classical genetics no longer exists.
