Abstract
The impact of an X(Z) chromosome derivative, the In(1)T2,y(mos)w(Yl)sn (mYl) strain, on mutation and reversion frequencies in strains with th e unstable yellow gene is analyzed. These strains were isolated during a yellow mutation outbreak observed in the natural population of Dros ophila melanogaster in Uman' (Ukraine) from 1982 to 1991. The In(1)T2, y(mos)w(Yl)sn(mYl) chromosome was shown to suppress yellow gene mutabi lity and activate singed gene mutability. A possible mechanism of homo logous suppression and destabilization is considered.
