Trofim Denisovich Lysenko was a Soviet agronomist and biologist known for his controversial agricultural theories. He rejected Mendelian genetics and promoted ideas based on the inheritance of acquired characteristics, which he believed could improve crop yields. His methods were widely adopted in the Soviet Union during the mid-20th century, leading to significant political and scientific repercussions. Lysenko's influence extended beyond agriculture, as he played a key role in shaping Soviet biological research. His opposition to genetics led to the persecution of many scientists who supported traditional genetic theories. This conflict had lasting effects on the scientific community in the Soviet Union and hindered advancements in biological research.
