Abstract

Genetic school of Leningrad-St.-Petersburg University had been shaped up on the background and simultaneously as a witness of achievements of the Russian genetics in 20-30-th of the XX century. The process had been strongly influenced by the personal relations of Yu.A. Filipchenko, the founder of department of genetics and experimental zoology of Petrograd University, with Russian (N.K. Koltsov, N.r. Vavilov at al.) and foreign (Т.Н. Morgan and his students first of all) colleagues. An episode is presented about formation of contemporary theory of mutation process by the efforts and cooperation of several scientific schools: by work of G.J. Muller, N.V. Timofeev-Ressovsky, M.E. Lobashev etc
