[Persistent locus-specific instability of yellow(27-717) and Noth(Uc-1) in Drosophila melanogaster coincides with hobo multiplication].

ABSTRACT

According to FISH data the presence of multiple hobo element copies in the unstable yellow and Notch loci in y(2-717) and Uc-1 Drosophila melanogaster stocks, respectively, was found. Locus-specific instability in these strains is caused by hobo multiplication in the respective loci and its subsequent recombination with neighboring hobo copies rather than its insertion-excision.
