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.
摘要
根据荧光原位杂交（FISH）数据，分别在y(2-717)和Uc-1黑腹果蝇品系不稳定的黄色和Notch基因座中发现了多个hobo元件拷贝。这些品系中基因座特异性的不稳定性是由相应基因座中hobo元件的增殖及其随后与相邻hobo拷贝的重组引起的，而非其插入-切除。
