The impact of an XZ chromosome derivative, the In(1)T2,ymosWYIsnmYI strain, on mutation and reversion frequencies in strains with the unstable yellow gene is analyzed. These strains were isolated during a yellow mutation outbreak observed in the natural population of Drosophila melanogaster in Uman' (Ukraine) from 1982 to 1991. The In(1)T2,YmosWYIsnmYI chromosome was shown to suppress yellow gene mutability and activate singed gene mutability. A possible mechanism of homologous suppression and destabilization is considered.
分析了一种XZ染色体衍生物In(1)T2,ymosWYIsnmYI品系对具有不稳定黄色基因的品系中突变和回复突变频率的影响。这些品系是在1982年至1991年于乌克兰乌曼的黑腹果蝇自然种群中观察到的黄色突变爆发期间分离得到的。In(1)T2,YmosWYIsnmYI染色体被证明可抑制黄色基因突变性并激活焦刚毛基因突变性。同时考虑了同源抑制和去稳定化的可能机制。
