  1. As analyzed, ( 1 ) the rapd technique is highly sensitive to investigating genetic diversity in t. lepturus and e. muticus. t. lepturus exhibits lower polymorphism and genetic diversity than e. muticus ; ( 2 ) according to the analysis of the partial mitochondrial 16s rrna gene sequences, a very low intraspecific variation and considerably high divergence among species were found, which reveals a dual nature of conservatism and variability in mitochondrial 16s rrna gene ; ( 3 ) five primers generate the species - speeific rapd sites and these sites can be served as the molecular markers for species identification and ( 4 ) it can be proved at dna variation level that t. lepturus and e. muticus are of two species respectively pertainiag to different genera, which supported the nelson taxonomic conclusion

    分析結果表明: ( 1 ) rapd技術研究黃海帶魚和小帶魚的遺傳多樣性具有較高的靈敏度和檢出率,帶魚的多態比例和遺傳多態度均較小帶魚的低; ( 2 )線粒體165出兇a基因序列在分析兩物種遺傳變異時表現出保守和變異的雙重特性,種內變異極小而種間較大: ( 3 ) 5個隨機引物擴增出種特異的ra衛d帶,可作為種間分子鑒定標記; ( 4 )研究證實帶魚和小帶魚是不同屬的兩個種,從而在分子水平上支持了nelson分類系統的觀點。
  2. Recently, we know the number of muntjac deer chromosomes varies from 6 to 48, and there are karyotypic polymorphism intra - species relationships. these animals are extremely useful for phylogenetic studies. in order to discuss the phylogenetic relationships of muntiacinae, we have studied the nuclear gene sequence of muntiacus muntjak, muntiacus crinifrons, muntiacus reevesi, and elaphodus cephalophus

    為了探討麂亞科動物間的親緣關系,本論文以赤麂( muntiacusmuntjak ) 、黑麂( muntiacuscrinifrons ) 、小麂( muntiacusreevesi )和毛冠鹿( elaphoduscephalophus )這4種麂亞科動物為材料,以核基因序列為研究對象,作進一步的研究。
  3. Second, the population genetic structure and genetic diversity of e. mollis were studied by using allozyme eletrophoresis and the electrophoretic data for 6 loci from 3 populations being xiangning, yicheng and pinglu populations in shanxi were got. the level of polymorphism was relatively higher than that of the insect - pollinated outcrossing species ( he = 0. 375 )

    用等位酶電泳法和biosys - 2軟體對山西翅果油樹種群的遺傳結構和遺傳多樣性進行了研究,通過對3個種群的6個等位酶位點的電泳分析,結果表明: 5個位點為多態位點, 1個單態位點。
  4. Differences with regard to the incidence of natural inversion polymorphism are likely to exist between species as well as between sub-species.

    自然倒位多型性的發生率在種間以及亞種間可能不同。
  5. The percentage of polymorphic sites, degree of genetic polymorphism and genetic distance were compared and the phylogenetic tree was constructed by neighbor - joining method. the partial mitochondrial 16s rrna gene was amplified by polymerase chain reaction ( pcr ) and the pcr products were directly sequenced after purified. these sequences, together with the homologous sequences of another trichiuridae species lepidopus caudatus obtained from genbank were used to analyze nucleotide difference and to establish a upgma phylogenetic tree by means of biological informatics

    汝us價ay1830 )各12個個體進行rapd分析,對比多態位點比例、遺傳多態度以及遺傳距離,並構建neighbor - join噸系統樹;通過pcr擴增出線粒體165rrna基因,純化后直接測序,利用生物信息學方法進行序列分析和核昔酸變異比較,結合ge紅bar止中大西洋叉尾帶魚( lepid (護腳caud玫tuseuphrasen1788 )同源序列構建u甲cm叭系統樹。
  6. Twelve primers selected from 100 random primers amplified 254 frangments in 14 species of cymbidium, in which 243 segments are polymorphic. the rate of polymorphism was 95. 7 %. and all the segments were ranging from 200bp to 2200bp

    從100個隨機引物中篩選出12個隨機引物,對蘭屬植物14種材料進行隨機擴增,共得到254條帶,多態性帶有243條,多態性百分率為95 . 7 。
  7. Thus, a genetic polymorphism of species in a balanced equilibrium cannot be established

    因此于平衡狀態下,物種之基因多態性並無法完成。
