Mutations were not found from 20 father - offspring pairs . conclusion the complex pcr is a rapid and simple method for forensic medicine casework . the three y - str loci are very suitable to forensic medicine analysis and paternity test 結(jié)論( 1 ) y染色體dys39o 、 dys391和dys393基因座多態(tài)性較高,本實(shí)驗(yàn)所得太原地區(qū)漢族男性dys390 、 dys391和dys393基因座等位基因和基因多樣性數(shù)據(jù)可應(yīng)用于法醫(yī)學(xué)鑒定和遺傳學(xué)分析。
The genotypic diversity of 30 strains of marine actinomycetes possessing strong antitumor activity ( id50 > 200 ) , 15 of which were isolated by my collaborate was analysed , by 16s ardra , which showed 17 rflp types , and indicated relatively rich genotypic diversity among these actinomycetes 對本室先后分離到的30株具有較強(qiáng)抗腫瘤活性( id _ ( 50 ) 200 )的海洋放線菌進(jìn)行基因多樣性分析。 16sardra表明這30株菌株之間存在較大的基因多樣性,共有17種不同的rflp類型。
Primers of ecori were signed with fluorescent dye and four pairs of primers were selected from twenty - four pairs . 261 dna fragments were generated by the four pairs of primers in forty - three individuals sampled . percentage of polymorphic bands is 51 % , the value of shannon index ( i ) is 0 . 086 and nei ' s gene diversity ( h ) is 0 . 151 統(tǒng)計(jì)這些aflp表型帶標(biāo)記,用popgene軟件計(jì)算各種多樣性數(shù)據(jù)( ppb值為51 , shannon多樣性指數(shù)為0 . 086 , nei ' s基因多樣性值為0 . 151 ) :用ntsys軟件計(jì)算各個(gè)樣品間的相似性系數(shù),并用upgma法基于相似性系數(shù)進(jìn)行聚類分析,構(gòu)建樹狀圖,它們可反映出元寶山冷杉種群內(nèi)個(gè)體間的遺傳關(guān)系。
Several results were concluded : firstly , the population of t . jackii was decreasing sharply and its living area was contracting , so the percentage of genetic variance among t . jackii populations was lower than that within its population ; secondly , its genetic diversity index was relatively high ; thirdly , according to its gene flow index , the population disintegration of the species could be prevented by genetic communication among populations of the species ; finally , the similar index between the populations from jiangshi nature reserve and from xufan reservoir was higher than that between the populations from jiangshi nature reserve and from xufanggeng , corresponding with the fact that it is nearer between jiangshi nature reserve and xufan reservoir than that between jiangshi nature reserve and xufanggeng 2 、長葉榧的遺傳多樣性分析,分析了多態(tài)位點(diǎn)百分率( percentageofpolymorphicsites ) 、 nei氏基因多樣性指數(shù)( nei ’ sgenediversityindex ) 、 shannon信息指數(shù)( shannon ’ sinformationindex ) 、居群間的相似系數(shù)( geneticsimilarityindex )和遺傳距離( geneticdistance ) 、遺傳變異在居群間和居群內(nèi)的分布( thepercentageofvarianceamongandwithinpopulation )及基因流( geneflow ) 。結(jié)論是:分布在群體間的遺傳變異較分布在群體內(nèi)的遺傳變異小,說明該生物的分布范圍越來越狹小。
