The gayal (Bos frontalis) in China is a very rare semi-wild and semi-domestic bovine species. There still exist remarkable divergences on the gayal??s origin and taxonomic status. In the present study...
中国傣族、景颇族人群中与艾滋病相关的CCR5△32、CCR2b-64I、SDF1-3′A等位基因多态性分布 Distribution of the HIV/AIDS Associated CCR5△32,CCR2b-64I,SDF1-3′A Allelesin Chinese Dai and Chingpaw Populations from Dehong Autonomous Prefecture of Yunnan Province
傣族 景颇族 基因多态性 趋化因子受体-5 趋化因子受体-2 人类免疫缺陷病毒1
2008/1/16
摘要为了调查HIV-1感染相关的等位基因CCR5△32、CCR2b-64I、SDF1-3′A在我国云南省德宏州傣族景颇族人群中的频率和多态性分布，此课题以101例傣族和113例景颇族人群为研究对象,应用PCR、PCR-RFLP(聚合酶链反应-限制性片段长度多态性)分析方法进行检测,计算突变基因频率；并对其群体分布、性别分布进行统计学分析。结果表明，中国傣族景颇族人群中未发现CCR5△32等位基因突...
云南纵坑切梢小蠹四个地理种群同工酶比较研究Comparative Studies of Isozymes in Four Geographical Populations of Tomicus piniperda L.for Yunnan Province
纵坑切梢小蠹 同工酶 等位基因频率 遗传距离 近交系数
2007/12/7
摘要采用不连续聚丙烯酰胺凝胶电泳技术研究了纵坑切梢小蠹(Tomicus piniperda L.)4个自然种群的9个同工酶基因座。4个种群均在Es-1、Es-2、Es-4、Mdh-1、Mdh-2及AAT-1基因座上存在遗传多态现象。路南长湖、楚雄、蒙自3种群间的遗传距离为0.0036～0.0173, 平均值为0.0105, 表明其遗传结构基本相似。丽江种群与上述3种群之间的遗传距离为0.1421～...
