摘要
性别的形成包括两个过程,即性别决定和性别分化。果蝇的性别控制研究包括性别决定、性别分化、性别鉴定、性别诱导和性别控制5个方面。性别决定是在两种不同发育途径之间的选择,它提供了一个研究基因调控的模式系统。果蝇的性别决定问题已经研究得相当详细[1。性别分化是使胚胎向着雌性或雄性发育的过程,决定了性别表型。果蝇的性别分化也取得了不少研究成果。近年来,许多重要的性别调控基因已被克隆和鉴定。随着果蝇基因组全序列测定的完成,果蝇的性别控制研究将会更为深入而完善。本文对与黑腹果蝇性别决定和性别分化相关的一些问题进行综述。
Sex developing needs two steps.One is sex determination,the other is sex differentiation.Sex control of D.melanogaster has five aspects,including sex determination,sex differentiation,sex appraisal,sex induction,and sex control.Sex determination is a choice between two development paths which provide a cascade about studying gene control pattern.Sex determination of D.melanogaster has been known in detail.Sex differentiation makes the embryo develop into female or male fruitfly.In recent years,many important sex control genes have been cloned.With the completion of Fruitfly Genome Project,the research about Drosophila will be carried out more deeply and completely.Sex determination and sex differentiation of D.melanogaster will be presented in this article.
