RAPD技术是Williams和Welsh等分别于1990年报道的一项DNA多态性检测技术，由于其具有简便、快捷等特点，被广泛应用于种属分类鉴定、基因图谱构建、以及物种亲缘关系和系统进

Furthermore, Ptychidio distinctly differed in osteological characters from other genera of Labeoninae, so it wasn't chosen as taxon of ingroup in phylogeny of Labeoninae. And Ptychidio's phylogenetic status can be ascertained only if more taxons of Cyprinidae be chosen and phylogeny of Cyprininae be solved in further research and molecular research.

此外，在特征分析时发现，卷口鱼属同野鲮亚科其它属的骨骼特征相差甚远，所以在分支系统学分析时没有被选择，有关其分类地位的确立，有待于今后在鲤科分支系统学研究中和分子生物学资料的研究中解决。

In addition, the phylogenetic relationship among several genera of Portunidea was discussed using Eriochier sinensis as the out-group.

Sis as the out-group. The molecular phylogenetic tree was constructed by NJ method using software MEGA 3.1, and three populations of M. nipponense were clustered first and then clustered with M. hainariense; M. rosenbergii and M. malcolmsonii, as well as M. Icr and M. latimanus had a closer genetic relationship and were clustered first, then they were clustered with M. carcinus and M. equidens, and finally with Fenneropenaeus chinensis.

用MEGA 3.1软件中的NJ法构建的分子进化树，日本沼虾3个群体先聚在一起后与海南沼虾聚在一起；另外，罗氏沼虾与马氏沼虾、短腕沼虾与贪食沼虾亲缘关系较近先聚在一起，然后再与大臂沼虾和等齿沼虾聚在一起，最后才与外群中国明对虾聚在一起。

Phylogenetic relationships among the 18 original genera of the palm family were investigated using two DNA sequence data sets derived from matK, the maturase - coding gene located in an intron of the plastid gene trnK, and the internal transcribed spacer region of 18S-26S nuclear ribosomal DNA to examine relationships in 18 generas of chinese palm family.
