用X射线照射黑腹果蝇幼虫，诱导其体细胞互换，形成带有遗传标记的花叶区域。马赛克胸膜硬化症与马赛克胸膜硬化症的关联频率符合随机关联。马赛克胸膜和马赛克腿的关联比偶然发生的频率要高得多。结论：胸膜总是起源于腹侧，而不是背侧。早期作者明显不同的结果被重新解释为胚胎的不确定性，而不是幼虫对预期想象区域的确定。
Larvae ofDrosophila melanogasterwere irradiated with X-rays to induce somatic crossing over resulting in genetically marked mosaic areas. Mosaic sternopleural sclerites were associated with mosaic mesonta in frequencies compatible with random association. Association of mosaic sternopleurae and mosaic legs was significantly more frequent than accountable by chance. It is concluded that the sternopleura is always derived from the ventral, not from the dorsal, disk. Apparently differing results of earlier authors are reinterpreted in terms of embryonic indetermination as contrasted to larval determination of prospective imaginal areas.
