摘要

研究了一种单翼亚果蝇。缺失的翅膀被带有大毛囊和小毛囊的庞大结构所取代，显示出胸部的外观。遗传杂交表明，不可能通过简单杂交来选择该性状。单翅蝇在不同世代的数量一直很低。在一个案例中，还获得了一只无翼苍蝇。这种性状呈现出一种未知的遗传模式。

One-winged Drosophila subobscura: a phenotype with an obscure genetic basis

A line of one-winged Drosophila subobscura was studied. The absent wing is substituted by a bulky structure with macro and microchaetes, showing a thoracic appearance. Genetic crosses showed that there is no way to select for the trait by simple crossing. The number of one-winged flies in the various generations was always low. In one case a wingless fly was also obtained. The trait presents an unknown genetic pattern.
