用化学诱变法诱导出求偶歌不和谐突变体。这种X染色体突变导致D。雄性黑腹果蝇的声音输出，由它的翅膀振动指向雌性产生，包括非常长和响亮的音调脉冲。“然而，一个给定的脉冲序列开始时是正常的，除了最短的歌声之外，所有的信号最终都会变成多环和高振幅。由diss（地图位置，1-52;细胞学间隔，14 C1 -2至14 C4 -5）引起的异常歌曲进行了定量比较，突变杂音男性，其脉冲更均匀多环（由于突变映射在X染色体上的其他地方）。表达diss的男性或女性在几个“一般”行为中是正常的。然而，diss雄性不仅唱歌异常，而且在向雌性求爱时，它们也表现出比正常更长的交配延迟。这些减少似乎与diss苍蝇的视觉异常行为有关，至少部分是关于雄性求偶本身的测量，也是在更一般的视觉反应测试中。在测试diss男性或女性时发现了此类缺陷，并且视觉障碍的遗传病因被暂时映射到歌曲异常所在的同一位点。关于新歌突变（diss）和旧歌突变（cac），讨论了求偶歌唱行为和视觉系统功能之间的神经遗传学联系，旧歌突变也被证明与导致光诱导行为和生理异常的突变有关。
The dissonance mutant of courtship song was induced by chemical mutagenesis. This X-chromosomal mutation causes the D. melanogaster male's acoustical output, resulting from his wing vibrations directed at a female, to include very long and loud tone "pulses." Yet, a given train of pulses starts out as normal, with the signals in all but the shortest singing bouts eventually becoming polycyclic and high-amplitude. The aberrant songs caused by diss (map position, 1-52; cytological interval, 14C1-2 to 14C4-5) were quantitatively compared to those produced by mutant cacophony males, whose pulses are much more uniformly polycyclic (due to a mutation mapping elsewhere on the X chromosome). Males or females expressing diss are normal in several "general" behaviors. Yet diss males not only sing abnormally, but they also exhibit longer-than-normal mating latencies in their courtship of females. These decrements seem to be associated, at least in part, with visually aberrant behavior of diss flies--measured with regard to male courtship per se, and also in tests of more general visual responses. Such defects were found when testing diss males or females, and the genetic etiology of the visual impairments were provisionally mapped to the same locus to which the song abnormality has been localized. Neurogenetic connections between the control of courtship singing behavior and visual system functions are discussed with respect to the new song mutation (diss) and the older one (cac)--which also turned out to be genetically related to a mutation that causes abnormalities of light-induced behavior and physiology.
