[Emergence of new super-unstable mutations in the Drosophila melanogaster line with initial super-instability in the ocelliless locus].
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.
