  3. 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。
  4. The genetic relationship between isolates of europe and china was closer than china and north america ' s. the inner genetic diversity of chinese phylogenesis lineages is higher, at the same time the territorial genetic differentiation and evolution direction divergence have taken place. the mixed lineage in heilongjiang province indicated that the isolates distribution pattern of a. gallica in heilongjiang province accorded with the characteristic that the distribution was formed by adaptive radiation of common ancestral forms

    在以黑龍江省高盧蜜環菌為主的中國大陸發育系內部的遺傳分化程度較大而且遺傳多樣性較高，並出現了區域性的遺傳分異和進化方向的分歧，同時還證明了黑龍江省內高盧蜜環菌的分佈格局也符合由共同的遠古祖先種適應性輻射形成的特點。
  5. ( 5 ) the comparing of the sequence divergence values 0. 013 between these two subspecies ( the relevant sequences of the other subspecies of great bustard ( o. t tarda ) from genbank ) and 0. 005, 0. 006 among haplotypes in different subspecieses, suggested that genetic differentiation between subspecies was larger than populations, and the genetic diversity in interpopulation was higher than intrapopulation

    （ 5 ）與genbank中歐洲指名亞種（ o . ttarda ）的相應區域序列的比較顯示，兩亞種間的序列差異值為1 . 3 ，與亞種內不同單元型間的序列差異值0 . 5和0 . 6相比，說明大鴇亞種間遺傳分化較大，種群間遺傳多樣性水平稍高於種群內的。
  6. Sinensis to mainland of china occurred during late tertiary to early quaterary estimated according genetic divergence

    中華絨螯蟹向中國大陸淡水水域的擴散可能發生在第三紀末至第四紀初。
  7. Genetic divergence between rice germplasms of blast resistance and the major wa - cms - type restorers

    水稻抗稻瘟病資源與野敗型骨幹恢復系間的遺傳差異
  8. ( 2 ) the mechanism of pollination off. mollis. ( 3 ) e. mollis is a long - lived species, ( 4 ) a feature of the flora in the southwest of shanxi is its antiquity associated with prolonged geographical stability and no obvious extinction episodes caused by recent glaciations. genetic divergence over all populations was very low ( fst = 0. 019 )

    翅果油樹有較高的遺傳多樣性，主要原因可能是（ ? ）由翅果油樹種群的分佈格局所決定； （ ? ）翅果油樹是一種長壽命的植物； （ ? ）翅果油樹所生存的地質環境較為穩定； （ ? ）由翅果油樹的授粉機制所決定。
  9. All groups of microtus fortis showed polymorphism at most of the ten loci investigated. the electrophoretic mobilities of the small voles from heilongjiang revealed great divergence with the other three groups : the small voles from heilongjiang had their particular alleles at six loci ( es - 1, hbb, gpi, akp - 1, trf - 1, ce - 2 ) and the phenotypes of them were completely different at three ( es - 1, hbb, gpi - 1 ) of these loci. the genetic distances among the voles from hunan, ningxia and the big voles from heilongjiang were ranged from 0. 0633 to 0. 2107 while that between the small voles from heilongjiang and the other three groups were ranged from 0. 7068 to 0. 8953

    結果表明：四類東方田鼠在所觀察的10個生化位點上，大部分都存在著多態性現象；黑龍江小體型東方田鼠與其它三類東方田鼠的電泳結果差異較大，在es - 1 、 hbb 、 gpi - 1 、 akp - 1 、 trf 、 ce - 2六個位點土都存在其所特有的等位基因，其中es - 1 、 hbb和gpi - 1三位點上它的基因型與其它三類鼠完全不同；湖南、寧夏和黑龍江大體型東方田鼠三者間的遺傳距離在0 . 0633 0 . 2107之間，而黑龍江小體型東方田鼠與其它三類鼠的遺傳距離在0 . 7068 0 . 8953之間。
