gene diversity
Examples
- The results of issr analysis is ppb = 66 . 67 % , h = 0 . 2089 , i = 0 . 3172 . genetic diversity of issr is higher than that of allozymes . genetic diversity of d . pleiantha is higher than d . versipelis
六角莲的遗传多样性高于于八角莲，等位酶的多态位点比率p为55 . 6 ， issr的多态位点百分率均为70 . 83 ，基因多样性为0 . 2383 ， shannon多样性指数为0 . 3576 。 - Mutations were not found from 20 father - offspring pairs . conclusion the complex pcr is a rapid and simple method for forensic medicine casework . the three y - str loci are very suitable to forensic medicine analysis and paternity test
结论( 1 ) y染色体dys39o 、 dys391和dys393基因座多态性较高，本实验所得太原地区汉族男性dys390 、 dys391和dys393基因座等位基因和基因多样性数据可应用于法医学鉴定和遗传学分析。 - The genotypic diversity of 30 strains of marine actinomycetes possessing strong antitumor activity ( id50 > 200 ) , 15 of which were isolated by my collaborate was analysed , by 16s ardra , which showed 17 rflp types , and indicated relatively rich genotypic diversity among these actinomycetes
对本室先后分离到的30株具有较强抗肿瘤活性( id _ ( 50 ) 200 )的海洋放线菌进行基因多样性分析。 16sardra表明这30株菌株之间存在较大的基因多样性，共有17种不同的rflp类型。 - Primers of ecori were signed with fluorescent dye and four pairs of primers were selected from twenty - four pairs . 261 dna fragments were generated by the four pairs of primers in forty - three individuals sampled . percentage of polymorphic bands is 51 % , the value of shannon index ( i ) is 0 . 086 and nei ' s gene diversity ( h ) is 0 . 151
统计这些aflp表型带标记，用popgene软件计算各种多样性数据( ppb值为51 ， shannon多样性指数为0 . 086 ， nei ' s基因多样性值为0 . 151 ) ：用ntsys软件计算各个样品间的相似性系数，并用upgma法基于相似性系数进行聚类分析，构建树状图，它们可反映出元宝山冷杉种群内个体间的遗传关系。 - 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。
