Analysis of distribution of the several families of mobile genetic elements has been performed. The analysis dealt with the X chromosomes of male progeny from the crosses of individual males of Mutator strain (MS) with attached-X females. The experimental results demonstrated different localization of the elements gypsy and hobo in the salivary gland squashes of different males-brothers. Location of other elements under study--mdg1, 412, mdg3, copia, 297, 17.6, Beagle, BS, Doc, FB, Springer--was invariant in all larvae. The analysis is equal to the study of transposition events at the level of gametes. Thus, doubtless, the capability of gypsy and hobo to transpose in germ cells of the MS individuals has been detected. Mobilization of the elements occurs at premiotic stages of gametes' development, as indicated by appearance of the clusters of transpositions. In the process of studies on coincidence of gypsy and hobo transposition acts, independent character of the elements' movement has been revealed. It has been detected in the same experiment that the distribution of the gypsy copies in different cells of the same salivary gland varies strongly. All hybridization sites were divided into two groups: "constant" sites common for all cells and "additional" ones, whose locations did not coincide in neighbouring cells of salivary gland. The existence of additional sites is major evidence of gypsy transpositions in somatic cells of MS. Transposition events have been as well discovered for hobo in somatic cells.
