Abstract

The effects of visible light post-treatment on the spectrum and frequencies of gamma-ray-induced mutations at five specific loci and of macrodeletions of the X chromosome in post-meiotic male germ cells in mutant c(3)G17 of Drosophila melanogaster were studied. It was found that post-treatment by light decreased the yield of chromosome rearrangements to the extent of 1.5 to 2 times, but not that of point mutations.

摘要

研究了可见光后处理对黑腹果蝇突变体c(3)G17减数分裂后雄性生殖细胞中五个特定基因座的γ射线诱导突变的光谱和频率以及X染色体大缺失的影响。发现光后处理使染色体重排的产量降低了1.5至2倍,但点突变的产量未降低。
