RAPDs were used to study the genetic divergency and phylogenetic relationship of Chinese wild boar and 5 breeds or strains of domestic pigs, including Erhualian pig, Hongdenglong pig, Jiangquhai pig, Xiang pig and Yorkshire.

对二花脸猪、红灯笼猪、姜曲海猪、香猪、约克夏猪及华东地区野猪共24个个体进行了随机扩增多态DNA分析，以探讨家猪与野猪间的亲缘关系。

Also in the 3-D space, we assign the 20 amino acids to 20 vertices of the dodecahedron. By the symmetry of the dodecahedron we obtain 3-D representation of 20 amino acids, and 3-D graphical representation and the corresponding numerical sequence of protein sequences. And similarity and dissimilarity analysis based on the invariants of graphs and characteristics of numerical sequences are given for nine RNA secondary structures of RNA-3 of virus. We construct sequence phylogenetic tree of a group of cytochromes C protein.

在DNA三联体密码子表示的基础上，在半复平面上给出了蛋白质序列的非退化的2-D图形表示，同时利用复向量的主要特征—模和相位，给出了蛋白质序列的一种数值刻划，进一步在3-D空间里，把20种氨基酸分别分配给正12面体的20个顶点，根据正12面体的对称性得到了20种氨基酸的3-D表示，进而得到了蛋白质序列的3-D图形表示和对应的数字序列，并利用图的不变量和数字序列的特征比较了9种动物的神经元

The taxonomic studies of B. dorsalis complex by morphological and genetic characters are reviewed. It is helpful to apply the molecular approach to taxonomic and phylogenetic analysis for the complex. And the outlook of phylogenetics and behavioral study of the complex will be focuse...
