Abstract
Main features of mutagenesis induced in the double super-unstable syst em in Drosophila melanogaster males and females was studed earlier. Ve ry different y- and sc-alleles arised under the mutagenesis. These are differed one from another by the expression of yellow and scute loci. However, it was shown that the female's mutagenesis very differed fro m the male's one. The structure of a homologous chromosome has played an important role in the mutagenesis in Drosophila females. We found h ere that the homologous translocation in Y chromosome led to double de crease of the frequency of the mutagenesis in males. It is proposed th at interconnections between two homologous insersions are essential in the recombinational processes by which alleles change. The nature and mechanism of the sub-lethal allele's formation in the presense of tra nslocation in Y chromosome is discussed.
