We studied the associated mutagenesis in Drosophila melanogaster strains carrying the family of unstable mutations at the ocelliless locus. The latter was obtained by crosses between strains with mobilized Stalker (M-cytotype) and pi 2 strain (P-cytotype). Then, the males with super-unstable oc-mutations were crossed with females with attached X chromosomes, supporting P-M hybrid dysgenesis. In addition to frequent mutation changes at the ocelliless locus, active mutagenesis at other loci was also observed. More than 10% of new X chromosomal mutations were found to be super-unstable. Detailed description of super-unstable mutations at the white, pseudoscute and some other loci is presented.
我们研究了携带无眼位点不稳定突变家族的黑腹果蝇品系中的相关诱变作用。后者是通过具有可移动的Stalker（M细胞型）的品系与pi 2品系（P细胞型）杂交获得的。然后，将具有超不稳定oc突变的雄性与具有附着X染色体的雌性杂交，支持P-M杂种不育。除了无眼位点频繁的突变变化外，还观察到其他位点的活跃诱变。发现超过10%的新X染色体突变是超不稳定的。本文还介绍了白眼、拟盾片和其他一些位点的超不稳定突变的详细描述。
