That is not true and you know it
In the USSR, Muller supervised a large and productive lab, and organized work on medical genetics. Most of his work involved further explorations of genetics and radiation. There he completed his eugenics book, Out of the Night. By 1936, however, Stalin’s repressive policies and the rise of Lysenkoism was making the USSR an increasingly problematic place to live and work. Muller and much of the Russian genetics community did what they could to oppose Trofim Lysenko and his Larmarckian evolutionary theory, but Muller was soon forced to leave the Soviet Union after Stalin read a translation of his eugenics book and was “displeased by it, and...ordered an attack prepared against it.”[12]
But nice try.
