[The response of the genomic pattern of transposable elements TE412 to quantitative trait selection in Drosophila melanogaster].

The results of four selection-genetic experiments aimed at the genetic transformation of the quantitative trait controlled by the radius incompletus gene of Drosophila melanogaster are given. Directional (s+) and (s-)-selection was conducted. At the of end all the experiments, in (s+)-selection the radial vein of the wing was restored to the wild phenotype, in (s-)-selection complete elimination of the radial vein took place. In four variants of selection, different TE412 pattern was formed under (s+)-selection and (s-)-selection in final generations. Correlation coefficient between (s+)-selection and (s-)-selection is -0.576, p < 0.001. At the same time, correlation coefficient between two independent replications of (s+)-selection is 0.912, p < 0.001, and of (s-)-selection, 0.946, p < 0.001. Thus, the availability of associated response to the selection of a quantitative trait and to the TE412 pattern is experimentally proved. Three hypotheses of the possible TE behaviour under selection are discussed.
