摘要 利用性嵌合将果蝇求爱歌曲的控制映射到中枢神经系统。一些雌雄马赛克会跟随雌性，并向雌性伸出翅膀。这种行为与男性脑组织有关。只有大约三分之二的求爱马赛克在求爱时有正常的脉搏曲；其余的在展开和振动翅膀时会产生异常的声音输出，或者根本没有声音。正常脉搏鸣曲与腹侧胸神经节的男性基因型关系最为密切。这些神经节中最接近暂定焦点的子结构是腹侧中胸神经节。这种对脉搏鸣叫的关注是霸道的，因为左侧或右侧神经节中的男性组织足以让左右翼正常鸣叫。正弦歌曲仅由一些具有正常脉冲歌曲的马赛克产生。正弦歌的绘制并没有得出明确的焦点，但大脑和胸神经节特定区域的基因型往往与正弦歌的产生有关。
SummaryThe control of courtship song inDrosophila melanogaster was mapped to the central nervous system using sex mosaics. Some male-female mosaics follow females and extend their wings at them. This behavior is associated with male brain tissue. Only about two-thirds of the courting mosaics have a normal pulse song when courting; the rest produces abnormal sonic output when extending and vibrating their wings, or no sound at all. Normal pulse song is most closely associated with male genotype in the ventral thoracic ganglia. The substructure in these ganglia closest to the tentative focus is the ventral mesothoracic neuromere. This focus for pulse song is domineering, in that male tissue in either the left or right ganglion is sufficient for normal singing by both the left and right wing. Sine song was produced by only some of the mosaics with normal pulse song. Mapping of the sine song did not lead to a definitive focus, but the genotype of particular regions of the brain and thoracic ganglia tend to be associated with production of sine song.
