anseriformes meaning in Chinese
雁形目
雁鸭目
Examples
- 3 . the sequence variation of mitochondria ! cytochrome b gene and phylogenetic relationships of anseriformes were studied based on the complete cytochrome b gene sequences of 19 species combined with 4 species got from genbank
3 、研究测定雁形目鸟类19f mtdna细胞色素b基因全序列，结合genbank中的4个物种，分析了雁形目鸟类细胞色素b基因的序列变异及其分子系统发生。 - 2 . the sequences variation of mitochondrial 12s rrna gene and phylogenetic relationships of anseriformes were studied based on the complete 12s rrna gene sequences of 36 living species of which 19 species were sequenced and other related data obtained from genbank
2 、研究测定了雁形目( anseriformes ) 19种mtdna12srrna基因全序列，结合genbank中雁形目种类相关数据，分析了雁形目36种鸟类12srrna基因序列变异及其分子系统发生。 - 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。 - 1 . because the taxonomic division is rather complex and has been much disputed and revised , in this part , we will review the classification and phylogeny of families , subfamilies and tribes of anseriformes based on morphology , ethology , osteology , mitochondrial and nuclear dna restriction fragment length polymorphism , single - copy nuclear dna hybridization and the sequences of mitochondrial gene analysis referring to the different definition , classification and phylogenetic relationships of the families , subfamilies and tribes of anseriformes . the controversial questions and deficiency in the systematic studies of anseriformes were pointed out
具体包括以下几个部分： 1 、针对雁形目鸟类异常复杂的分类状况及分类上存在的争议，根据雁形目鸟类的形态学、行为学、骨骼学、角蛋白、线粒体与核dna酶切片段长度多态、单拷贝核dna - dna杂交及线粒体基因dna序列分析等方面的研究，对雁形目鸟类分类中科、亚科和族的划分及其相互间的系统发生关系进行综述，分析系统学研究中存在的不足，提出了雁形目鸟类分类中急需解决的问题。
