There are three frequently used method : distance method , maximum parsimony method , and maximum likelihood method 目前常用的構(gòu)建發(fā)生樹的方法有三種,即距離法、最大簡約法和最大似然法。
The results are agreeable with morphological taxonomy . the software mega was used to analyze the molecular phylogeny and phylogenetic trees were constructed with the neighbor - joining method and the maximum parsimony method 對所得的基因序列用mega軟件包進行系統(tǒng)進化分析, nj法和最大簡約法( mp )構(gòu)建毛冠鹿和麂屬3種動物的分子系統(tǒng)進化樹。
Phylogenetic relationship of sequences was constructed by neighbor - joining method in mega and maximum parsimony algorithm in paup . the same two groups were showed in the results , and the group b sequences were more similar to two sequences of caiman crocodilus Nj法和mp法構(gòu)建的系統(tǒng)樹極為相似, 10種序列聚為兩支( a和b ) ,分支b與凱門鱷的兩種序列的親緣關(guān)系較近。
Pairwise comparisons of uncorrected sequences distances and kimura 2 - parameter distances were calculated and molecular phylogenetic trees were reconstructed by using the neighbor - joining ( nj ) , maximum parsimony ( mp ) , maximum likelihood ( ml ) methods 分析了?科魚類s7核糖體蛋白基因內(nèi)含子2序列,計算了p - distance和kimura2 - parameter遺傳距離,并用鄰接法、最大簡約法、最大似然法重建了?科魚類分子系統(tǒng)樹。
