[Complex instability in the system of hobo and stalker mobile element interaction in Drosophila melanogaster].

A number of mutations in different Drosophila loci resulted from the relationship between hobo and stalker mobile elements. In this investigation an insertion from the parential white mutation-waG-was cloned. And the Doc element, that is the reason of the mutation, is not moving in the observed instability system. But transpositions of the copia-like elements (e.g. mdg1, 2, 3 and copia) were shown in this system. A cases of chromosomal rearrangements and abnormal recombination in compound with transpositions of different mobile elements were found. Thus, the system of instability could be explained in terms of universal mechanism which involved both transpositions and recombinations phenomena.
