The president of the Soviet Agriculture Academy, Nikolai Vavilov, who had been Lysenko’s mentor, but later denounced him, was sent to prison and died there, while Soviet genetics research was effectively destroyed. Research and teaching in the fields of neurophysiology, cell biology, and many other biological disciplines were harmed or banned.“

The famous Soviet geneticist and president of the Agriculture Academy, Nikolai Vavilov, was arrested in 1940 and died in prison in 1943.”

“After the appointment of Lysenko as head of the Soviet Academy of Agricultural Sciences, classical genetics began to be publicly called “fascist science”
