摘要
为探讨首都医科大学长爪沙鼠群体的遗传状况,应用生化基因位点遗传检测方法,测定初始和生物净化长爪沙鼠群体27个生化位点等位基因的分布。结果表明,2个长爪沙鼠群体均具有丰富的遗传多样性;生物净化群体与初始群体比较有7.14%的基因丢失率,但尚未出现明显的遗传分化现象(FST<0.05);群体均偏离了哈迪-温伯格平衡(P<0.05)。
To study population genetic eha/aeteristie of Mongolian Gerbil of Capital University of Midical Sciences, 27 loci of two colonies were determined by monitoring methods of biochemical markers. The result showed that the two colonies had high level of genetic diversity and low degree of genetic similarity; compared with the original colony, the biological purifying colony had 7.14% gene lost, but the two colonied did not appear obvious genetic differentiation（ FST 〈 0.05） ; the population deviated from Hardy-Weinberg equilibrium（ P 〈 0.05）.
