系统发生研究 meaning in English
phylogenetic study
Examples
- Application of genetic marker technique to the study of systematics , biodiversity and phylogenetics for marine copepods
遗传标记技术在海洋桡足类生物多样性和系统发生研究中的应用 - The phylogenetic relationship of the mitten crab and other grapsoid crabs suggested that eriocheir is monophyletic , and the estimated divergence time of the mitten crabs with its marine varunid ancestor is about 8 . 9 ~ 10 . 9 mya
淡水蟹类的系统发生研究显示，华溪蟹属与仿溪蟹属起源于一个共同的海生蟹类祖先，二者之间的歧异时间在36 44mya 。 - Among avian orders , the anseriformes ( screamers and waterfowls ) are a morphologically and biologically diverse group containing ca . 150 species distributed worldwide except antarctica . this paper will review the phylogeny of anseriformes firstly and then discuss the molecular phylogeny of anseriformes based on the genetic variation of mitochondrial 12s rrna gene and cytochrome b gene respectively
本文首先对雁形目鸟类的系统发生研究进行了综述，然后分别基于雁形目鸟类线粒体dna12srrna基因和细胞色素b基因全序列的遗传变异分析，探讨了雁形目鸟类分子系统发生。 - This research reviewed the relationships of the myriapods to other arthropoda , based on morphological and molecular sequence data and the studies of developmental biology . the review was followed the major controversies in the higher - level phylogeny of myriapods . the complete 18s rrna sequences of four groups of myriapoda plus hexapoda ( protura , diplura , insecta ) and crustacea were used for phylogenetic study
本研究首先从形态学性状、分子性状( dna和蛋白质)以及结合形态和分子性状、发育生物学的研究等方面对多足类动物与其他节肢动物之间的亲缘关系进行了综述，同时对多足类的系统发生研究进行了综述。 - The chilopoda and diplopoda are monophyletic group respectively . although there are some limitations , the mitochondrial dna as a model system is being used as a powerful tool in phylogeny analysis . it is the only molecular marker that can be used in the phylogenetic studies at genomic level
线粒体dna基因组全序列作为研究动物系统发生的模式系统，虽然有一定的缺陷，但仍是生物学家研究系统进化最有力的工具，它是目前唯一可以提供基因组水平上进行系统发生研究的分子标记。
