gene diversity meaning in Chinese
基因多样性
Examples
- 2479 at species level , and they were 0 . 2182 , 0 . 1684 and 0 . 1881 at population level . the result of shannon " s information index analysis was correspondent with the result of nei " s gene diversity index analysis
其基因流的期望值达1 . 6899 ，从理论上讲，若nm 1 ，群体间的基因交流可以防止遗传漂变造成的群体分化。 - The gene relative information entropy diversity , by computer simulation , establish the linear connection between gene relative information entropy and gene diversity , detemined coefficient is 0 . 9929
同时建立了基因相对信息量多样度的测量方法，通过模拟得出基因相对信息量多样度与基因多样度间存在线性关系，决定系数为0 . 9929 。 - The data was analyzed with three softwares : tfpga popgene32 and amova155 which are tools for molecular analysis . the percentage of polymorphic sites at species level was 86 . 93 % , and they were 83 % 68 % and 80 % at population level . nei " s gene diversity index was 0
但长叶榧还保留了较高的遗传多样性：物种水平的nei氏基因多样度指数达到0 . 2479 ， shannon信息指数也达到了0 . 3807 ，而其物种水平的多态位点百分率高达86 . 93 。 - 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。 - The results showed that the mean proportion of polymorphic loci ( ppb ) of anabasis aphylla , which comprised 3 subpopulations ( 58 individuals sampled ) , generated by 16 primers was 94 . 56 % , the value of ppb of ceratocarpus arenarius , which had 4 subpopulations ( 80 individuals sampled ) , using 16 primers was 98 . 00 % . the paper had proved that the higher genetic diversity and the genetic differentiation existed in the populations of boih anabasis aphylla and ceratocarpus arenarius , while the latter had much more genetic diversity than the former . moreover , the study discussed the shannon information index and nei ' s gene diversity index of the two species natural populations , which indicated that there were more genetic variations within the subpopu
另外，通过rapd资料的聚类分析及相关性分析研究，发现无叶假木贼和角果藜自然种群的遗传结构与绿洲沙漠过渡带的微生境生态因子(主要是土壤因子)相关，其中无叶假木贼亚种群遗传多样性水平不仅与土壤含水量( w ) 、钾钠离子浓度( k + na )和氯离子浓度( cl )呈显著的正相关( p 0 . 05 ) ，还与土壤中有机质( som ) 、全氮( nt )和全磷( pt )含量呈显著的负相关；同时，角果藜种群的遗传多样性水平与土壤中有机质( som )和全氮( nt )含量呈显著的正相关，而与co _ 3 ~ ( 2 - )浓度呈显著的负相关；除此之外，其它土壤生态因子与两物种遗传多样性水平的相关性均不显著(卜0 . 05 ) 。
