距离矩阵
Examples
- A series of computing indexes were applied to obtain genetic distance matrixes . nj tree
生y拔1500叶000m的湿润山坡或林下。 - In chapter five , morphological observations and its sequence analyses of monostromaceae in china were made . distance matrix and phylogenetic trees were obtained as described in last paragraph
在第五部分，采用its序列分析结合传统形态观察的方法，对我国礁膜科样品进行了研究，方法同前。 - In chapter three , genomic dna were extracted from four individuals from sinotubimorpha porracea and grateloupia filicina , respectively and from g . livida as a control . sixties primers were used for dna amplification and a total of 120 amplification products range from 250bp to 2500bp were generated . distance matrix and dendrograms were obtained as described in last paragraph
在第三部分，应用ctab法提取了管形藻、蜈蚣藻各4个个体及作为对照的舌状蜈蚣藻的基因组dna ， 60个引物的rapd分析获得120个片段大小在250 - 2500bp之间的扩增片段，遗传距离和聚类分析同前。 - Sixties primers were used for dna amplification and a total of 237 amplification products range from 450bp to 2500bp were generated . a similarity matrix for all pairwise comparisons was calculated using nei and li ' s formula and then transformed to distance matrix . dendrograms were constructed by applying unweighted pair - group arithmetic average ( upgma ) and neighboring - jointing cluster analyses using the phylip software
在第二部分，应用改进的ctab法提取了石莼属和浒苔属各3个种及作为对照的刚毛藻的基因组dna ， 60个引物被用于扩增，共获得237个片段大小在450 - 2500bp之间的扩增片段，依据nei和li ( 1979 )的公式计算出样品成对比较的相似性距阵并换算成遗传距离，应用phylip软件包，按照upgma法和n - j法分别构建聚类图。
