| 摘 要： | 目的调查Z:ZCLA长爪沙鼠原种群普通级长爪沙鼠的遗传多样性。方法用本实验室自行建立的长爪沙鼠19个生化基因位点的乙酸纤维素膜电泳技术并结合基本群体遗传学指标研究了普通级Z:ZCLA长爪沙鼠100个家系的遗传多态性。结果Z:ZCLA长爪沙鼠在Es-1、Car-2、Hbb、Gpi-1、Cs-1、Ce-2I、dh-l、Mod-1呈单态,在Es-2、Es-3、Es-4、Es-6、Es-8、Es-9、Es-10、pd-1、gm-1、Trf、Akp-1个位点上呈现多态性,等位基因从2~4个不等,平均等位基因数3.0,平均杂合度0.512,平均多态信息量0.455。结论提示目前本群遗传多样性水平处于中度多态。

| Abstract: | Objective To investigate the genetic diversity of the original population of Z:ZCLA Mongolian gerbils by biochemical markers.Methods 19 biochemical loci as markers were used to detect the genetic variation in the conventional closed colony of Z:ZCLA Mongolian gerbils.Results The loci Es-1,Car-2,Hbb,Gpi-1,Cs-1,Ce-2,Idh-l,Mod-1 had only one allele,while the loci Es-2,Es-3,Es-4,Es-6,Es-8,Es-9,Es-10,Gpd-1,Pgm-1,Trf,Akp-1 had two to four alleles,respectively.The average heterozygosity,allele number and polymorphism information content were recorded as 0.512,3.0 and 0.455 respectively.Conclusion The analysis of polymorphism information content on 11 biochemical gene marker loci of this conventional closed colony of Z:ZCLA Mongolian gerbils revealed the genetic diversity at a moderate level. |
