| 摘 要： | 通过筛选的28个多态性较好的微卫星标记,检测了太湖鹅群体的遗传多样性,结果表明,28个微卫星位点均表现出多态性,总共检测到87个等位基因,平均等位基因数为3.1071个;群体多态信息含量为0.4450,杂合度为0.5206。瓶颈效应分析结果表明该群体已偏离了突变-漂移平衡,近期可能经历了瓶颈效应,种群数量曾经下降。根据遗传多样性检测数据,提出保护与开发建议。

| Abstract: | In the present study,we report a genetic diversity study of Taihu geese by use of 28 microsatellite markers.The microsatellite marker set analysed provided 87 alleles,with mean 3.1071 alleles per locus.All the microsatellites were polymorphic.The mean Polymorphism information content(PIC) and expected hererozygosity(H) were 0.4450 and 0.5206,respectively,indicating considerable genetic variation in this population.Genetic bottleneck hypotheses were also explored.Our data suggest that the Taihu goose populat... |
