genetic diversity index meaning in Chinese
遗传多样性指数
Examples
- But the population genetic that based on the statistic model ca n ' t explain the entropy change disciplinarian in the process of evolution , and the genetic diversity index system not enough prefect
但目前建立在统计学基础上的群体遗传学尚未阐述清楚进化过程群体的熵变规律，而且遗传多态性分析的指标体系不够完善，因而必须用信息论方法科学描述和丰富遗传多样性的指标体系。 - So must use information theory method depict and abundant the genetic diversity index system . in addition to , the introduce of molecule biology technology and the research of nucleotide sequence evolutive give a new method for population genetic , so must do deeply research about the analysis method of dna sequence data = the research main about the follows : there are three parts about the information model of population genetic : one about the shannon information entropy property of equilibrium population and the entropy change in the process of establish equilibrium ; another research is about the diversity measure - ment of genetic variation ; lastly , research the shannon information measurement about the disequilibrium gene variation . the result is : 1 to a definite gene distribution , the genotype entropy reach the maximum at the equilibrium population , the process of population from disequilibrium to equilibrium , the entropy get large and large
此外，分子生物技术的介入及核苷酸序列进化的研究都为群体遗传学的深入研究提供了新的途径，但关于dna序列数据的分析方法需要作进一步的研究。本研究主要体现在以下几个方面： (一)关于群体遗传学的信息论模型研究，主要分为三部分内容：一是群体平衡的shannon信息熵的性质和群体平衡建立的熵变性质；二是群体遗传多样性测度的研究；三是非平衡群体的基因变异测量shannon信息量的方法研究。得到了如下结论： 1 、平衡群体的shannon信息熵最大，群体平衡的过程是熵的增大过程。 - Several results were concluded : firstly , the population of t . jackii was decreasing sharply and its living area was contracting , so the percentage of genetic variance among t . jackii populations was lower than that within its population ; secondly , its genetic diversity index was relatively high ; thirdly , according to its gene flow index , the population disintegration of the species could be prevented by genetic communication among populations of the species ; finally , the similar index between the populations from jiangshi nature reserve and from xufan reservoir was higher than that between the populations from jiangshi nature reserve and from xufanggeng , corresponding with the fact that it is nearer between jiangshi nature reserve and xufan reservoir than that between jiangshi nature reserve and xufanggeng
2 、长叶榧的遗传多样性分析，分析了多态位点百分率( percentageofpolymorphicsites ) 、 nei氏基因多样性指数( nei ’ sgenediversityindex ) 、 shannon信息指数( shannon ’ sinformationindex ) 、居群间的相似系数( geneticsimilarityindex )和遗传距离( geneticdistance ) 、遗传变异在居群间和居群内的分布( thepercentageofvarianceamongandwithinpopulation )及基因流( geneflow ) 。结论是：分布在群体间的遗传变异较分布在群体内的遗传变异小，说明该生物的分布范围越来越狭小。
