[Occurrence of chromosome aberrations in females heterozygous for deletion MS2-10: maternal effect].
The mutagenic effect of the paracentromeric heterochromatin deletion MS2-10 was studied in direct and reciprocal crosses of laboratory and wild-type lines of Drosophila melanogaster. The effect of deletion MS2-10 depended on the opposite chromosome. This was shown for the combination of autosome MS2-10 with autosome 2 from the Berlin wild line, but when MS2-10 was combined with an autosome from lines Canton S and pr pk cn, the effect was absent. When deletion MS2-10 was inherited from the female parent and the opposite chromosome from the male parent, the effect of the deletion was present, but it was absent in males heterozygous for MS2-10, obtained in reciprocal crosses. In maternal effect, this case of mutagenesis is similar to hybrid dysgenesis. However, the pattern of P-M dysgenesis was shown to differ from the type of mutagenesis described in the present work.
