[A new approach to polygene mapping. Localization of genes, controlling the adaptation level of closely related lines of Drosophila melanogaster].
The phenomenon of hitch-hiking of dispersed mobile elements (molecular markers) is proposed as a new approach to polygene mapping. Retrotransposons MDG1 and copia are used as molecular markers to reveal chromosome 2 segments controlling high fitness level in Drosophila melanogaster. Comparison of closely related Drosophila melanogaster stocks with different fitness level demonstrates the role of pericentromeric region of chromosome 2 in the control of adaptive value.
