The Soviet delegation at the IV International Congress on Human Genetics in Paris in 1971

The article is devoted to the participation of Soviet scientists in the IV International Congress on Human Genetics, which was held in Paris in 1971. This event is analyzed in the context of the development of Soviet-French scientific relations. Excerpts from reports of well-known domestic geneticists are given, reflecting both the level of scientific activity and the state of foreign science. The unrealized initiative of N.P. Dubinin to hold a congress in Moscow and a forum in Mexico City in 1976 are mentioned. Despite the small number of the delegation, representatives of the USSR were elected to the organizing committee of both congresses. It is safe to say that the trip to France played an important role in the development of human genetics in the USSR, and also stimulated research on cytogenetics, which became more extensive and systematic.
