It is generally adopted that the homoeotic gene proboscipedia causes the transformation of the distal parts of proboscis into corresponding tarsal or antennal (aristal) segments. It is shown that actually the homoeotic effect of the mutation proboscipedia consists in the transformation of the oral lobes of proboscis into a whole prothoracic leg. Sometimes the distal parts of the homoeotic leg (segments of tarsus, claws) can coexist with or be substituted for by the aristal filaments. The transformation of oral lobes of proboscic into the leg is most conspicuous at 29 degrees C, while at 16 degrees C the substitution of tarsal structures by aristal ones is observed more frequently. The homology between the corresponding elements of the proboscis, legs and antenna (as revealed by the pattern of homoeosis) is discussed.
一般认为，同源异型基因“触须足基因”会导致口器的远端部分转化为相应的跗节或触角（芒）节段。研究表明，实际上“触须足基因”突变的同源异型效应在于口器的口叶转化为一条完整的前胸腿。有时，同源异型腿的远端部分（跗节、爪的节段）可以与芒状细丝共存或被其替代。在29摄氏度时，口器口叶向腿的转化最为明显，而在16摄氏度时，跗节结构被芒状结构替代的情况更频繁出现。文中还讨论了口器、腿和触角相应元素之间的同源性（由同源异型模式揭示）。
