Scientists at Scripps Institution of Oceanography at the University of California San Diego have discovered why some hybrids between populations of the same species don't develop as well as others. Th...
GENETIC ASSESSMENT OF CONNECTIVITY AMONG MARINE POPULATIONS
MARINE POPULATIONS GENETIC ASSESSMENT

We examined the population structure of the
black tiger prawn, Penaeus monodon Fabricius, 1798, in
the Indo-West Paci®c by analyzing the geographic distribution of elongation factor 1-alpha int...

摘要采用水平切片淀粉凝胶电泳的方法,对分布于我国5省的8个库蚊复组(Culex pipiens complex)野生群体的遗传多样性进行研究,分析了4个酶系统7个基因座(ME、MDH-1、MDH-2、MDH-3、GPD、EST-2、EST-3)的酶谱资料。结果显示:(1)群体内存在不同程度的遗传变异(He为0.098~0.41);(2)较低的基因流水平(Nm=0.64)使遗传漂变起主要作用,造成群...
栓皮栎天然群体SSR遗传多样性研究Genetic Diversity of Microsatellites(SSRs)of Natural Populations of Quercus variabilis
栓皮栎 微卫星(SSR) 遗传多样性 遗传分化
2008/1/8
摘要
利用微卫星(SSR)标记对我国4个省内的5个栓皮栎(Quercus variabilis Bl.)天然群体的遗传多样性进行了研究。16对SSR标记揭示了栓皮栎丰富的遗传多样性:等位基因数(A)平均8.4375个,有效等位基因数(Ne)平均为5.9512个,平均期望杂合度(He)0.8059,Nei多样性指数(h)为0.8041。栓皮栎自然分布区中心地带的群体具有较高的遗传多样性,而人为对森...

绵羊 微卫星 遗传多态性 分子系统发生
2008/1/8
摘要
分析了4个微卫星基因座BM143、OarHH35、OarAE101、BMS2508在7个绵羊群体(小尾寒羊、湖羊、乌珠穆沁羊、萨福克羊、多赛特羊、夏洛来羊、多赛特公羊×小尾寒羊母羊F1代杂种羊)286只绵羊中的遗传多态性。结果表明,这4个微卫星标记在7个绵羊群体中的等位基因数分别为9、11、14和9,其多态信息含量/有效等位基因数/杂合度分别为0.7073/3.7231/0.7314、0....
