Biography BELYAEV Nicholas
(19.09.1899 - 10.11.1937)

Student Chetverikov. Born s.Protasovo Kostroma family priest. In 1917, Mr.. graduated from high school and enrolled at the Petrograd Institute of Technology. However, soon left him as a child fascinated by biology, and in 1921. joined the biology department of Moscow University, graduating in 1925. In the same year he started working in the laboratory Chetverikov, and since 1928. appealed to the moth and devoted his whole life. He managed to publish 19 large works (440 pages. text), and left a mass of unpublished material, including the manuscript of the doctoral dissertation. Since childhood fascinated butterflies, NK Belyaev, a student began working for Chetverikov. Taking part in the collective study of natural populations of Drosophila, NK Belyaev worked with suburban D. phalerata and D.transversa (discovered and analyzed two interesting mutations) and participated in a population-genetic analysis of the D.melanogaster Gelendzhik. In phenogenetics NK Belyaev isledoval dependence of the color of caterpillars of butterflies from the external environment. He also worked kariosistematikoy: To determine the chromosome number in 38 species of butterflies from 16 families and 2 published an extensive article, which cited so far. NK Belyaev determined that in the evolution of butterflies play a major role not karyotypic changes, and point mutations. In 1928, Mr.. N. K. Belyaev began working in the department of Genetics and Breeding of the Central Asian Institute of sericulture. He spent the genetic analysis of incompletely-dominant trait melanisticheskoy color silkworm moths, showing its polymeric inheritance (1937). At the beginning of a silkworm he devoted much effort the study of inbreeding and the associated inbreeding depression. Worked as "artificial revival of" Grenier, ie. removal of dormancy (embryonic diapause) for several generations of butterflies in the summer. His method (1932) are still used in industrial silk. I took part in the meeting of the Central Asian tribal sericulture. N. Belyaev played a leading role in translating domestic silk for industrial hybridization. In 1932, Mr.. transferred to the Trans-Caucasian Institute of sericulture, leading the Department of Genetics and Breeding. A distinction between direct and reverse combinations of hybrids, revealed patterns of inheritance hybrids form cocoons. He studied the correlation of a number of characters in the silkworm and its important role in artificial or natural selection, having concluded the impossibility of a successful selection of all economically important characters. Executed in 1937
