[A.S. Serebrovskiĭ's experimental studies on induced mutagenesis].

The paper is devoted to A.S. Serebrovskiĭ's studies on induced mutagenesis. His first publication on X-ray induction of mutations in Drosophila appeared in 1928; this became a classical work and entered the golden fund of modern radiation genetics. Investigations of the scientists in the A.S. Serebrovskiĭ's laboratory as will as his own works on the analysis of radiation mutations at the achaete-scute complex have led to the development of the teaching about gene subdivision and made it possible to draw up a linear array of a gene from elementary subgenes, which have laid down the foundations of the modern molecular-genetic theory of gene.
