title: [Interaction between genes Mos and mwh expressed in somatic cells of Drosophila melanogaster].
abstract: Gene Mosaic (Mos) of chromosome 3 of Drosophila melanogaster was located by means of dominant markers Ly, Sb, and Dr. This gene was shown to be located between Ly and Sb in the centromeric region (45-50 map units). An analysis of interaction between Mos and mwh genes in cis and trans-heterozygotes showed a significant effect of the Mos gene on mutability (recombinogenesis) of chromosome mwh in somatic cells. In the cis heterozygote mwh Mos/++, the frequency of small mutant clones on wings of flies increased. In mwh/Mos heterozygotes, the Mos gene caused a significant reduction of dorsocentral and scutellar bristles (78% in mwh/Mos, 85% in mwh +/+ Mos, and 98% in mwh Mos/mwh +).
