这些情况表明,高山松虽然在基因组构成上与两个亲本基本一致,但基因在染色体组的空间排布上是存在差异的,这一点可以从rDNA-FISH中证明。

To overcome the premature of simple genetic algorithm, the calculating efficiency of SGA is improved by the following two ways; Firstly, in order to ensure convergence of algorithm and reduce influence factor of convergence, elitist selection and adapted crossover and mutation operator are adopted. Secondly, because this study deals with finding minimize volume of structure, to quicken convergence of this problem, in line with mechanics criterion the paper carry out mutation to some genes in chromosome according to variations of internal force. This will let algorithms to search answer with our hoping directions.

针对基本遗传算法存在早熟的问题,本文主要从两个方面进行了改进,首先为了保证算法的收敛和减少影响算法收敛因素,采用了最优保护策略和自适应的交叉和变异算子;其次,由于本文研究内容涉及求结构最小体积问题,为了加快此类问题的收敛速度,本文结合结构优化中的力学准则,对个体染色体中的某一段基因按照内力变化进行变异操作,使得算法按一定方向进行搜索最优解。

A detailed genetic linkage map covering a large region of the cotton genome based on some informative, portable and practical markers will provide a platform for evolutionary comparisons with other species,comparative mapping,QTL mapping and MAS,and structural and functional studies of the cotton genome.

采用SYBRGreenI随机掺入法,以Roche试剂盒为标准,比较两公司的DNA聚合酶,用鼠疫菌310 0 4建立荧光PCR反应体系;针对鼠疫耶尔森氏菌特异的染色体标识序列和质粒上F1抗原基因设计引物,检测其灵敏度和特异性,以盲测试验进行验证;在此基础上鉴定2 75株鼠疫耶尔森氏菌,并测试该法检测脏器污染模拟标本的灵敏度。

The codingoperator expresses the genes with N-decimal system floating numbers, and then the genes are divided into integer part and decimal part. The two parts are encoded into chromosomes respectively. The corresponding selection, crossover and mutation operators are designed with the theory of symbol encoding and the properties of N-decimal system floating numbers.

该编码算子首先将每个基因值用N进制的浮点数表示,然后将其分为整数部分和小数部分,分别重新编码组成染色体;相应的选择、交叉、变异算子采用符号编码的思想,充分利用N进制浮点数的特点进行设计。
