After a series f initial experiments and crrectins， the scientist’s hard wrk paid ff when the twin clne turkeys were hatched with nrmal feather and claws. This breakthrugh pssibly enabled peple t bring their adred pets back t life. Hwever， it bthered him frm time t time that their health was in pr cnditin because they were unable t resist illnesses. This drawback cast him dwn. Merely 2 weeks later， the clnes and their carrier died， which struck frustratin int his heart. He retired befre he attained his ambitin and became a member f an pera chrus t relieve his depressin.
Shrtly afterwards， the media published a cnservative argument bjecting t clning wing t mral prblems， and suggested the cnstitutin include cmpulsry regulatins t frbid btaining cmmercial prfits frm clning.
When interviewed， the scientist stared at the decratins n the ceiling， thinking fr a while， and then said， “I’m nt in favur f any arbitrary assumptin， but undertaking clning des differ frm the straightfrward prcedure f making lafs ut f flur. Until we accumulate enugh exact knwledge， any practice is in vain and is bund t fail. Altgether， being mre careful is reasnable r we may walk int a side rad.”
在最初一系列的实验和修正之后，科学家的辛苦工作终于取得了成功，一对双生的克隆火鸡孵化出来，羽毛和爪子都很正常。这一突破或许能让人们使他们喜爱的宠物死而复生。然而，使他不时地烦恼的是，因为它们无法抵抗疾病，使得它们的健康状况极差。这个缺点让他很沮丧。仅仅过了2个星期，克隆体和母体都死亡了，这使他内心里充满了挫折，他也因此在达到自己目标前就退休了，并选择加入歌剧合唱团来减轻消沉的感觉。
之后不久，媒体就因为道德问题而发表了反对克隆的保守论点，并且建议宪法应该包括强制性的法规禁止通过克隆获得商业利益。
当被采访时，科学家盯着天花板上的装饰物思考了一会儿，说：“我不赞成任何任意的假设，但是从事克隆与用面粉制作面包的简单过程确实不大相同。在我们积累了足够的准确知识前，任何实际操作都是徒劳无功的，注定会失败。总而言之，更加谨慎地对待克隆是合理的，否则我们或许会误入歧途。”
