| 摘 要： | 应用结构基因座和微卫星DNA两种遗传标记探讨长江三角洲白山羊群体遗传结构。结果表明,检测的9个结构基因座位上7个存在多态性,座位的基因平均杂合度、多态信息含量及有效等位基因数分别为0.1767、0.1457和1.2837;7个微卫星位点上共检测到110个等位基因,位点的基因平均杂合度、多态信息含量及有效等位基因数分别为0.8867、0.8774和11.2907。群体内的遗传变异程度相对较高,反映出丰富的遗传多样性,而且微卫星DNA标记揭示的遗传变异高于结构基因座。

| Abstract: | Genetic structure of Yangtse River Delta White Goat Population was discussed by using structural loci and microsatellite DNA markers.Results showed that there were 7 polymorphism loci on 9 tested loci.The average heterozygosity,polymorphism information content and effective number of alleles on structural loci are 0.1767,0.1457 and 1.2837;110 alleles were examined on 7 microsatellite sites and the average heterozygosity,polymorphism information content and effective number alleles on 7 microsatellite sites are 0.8867,0.8774 and 11.2907.Abundant of genetic diversity was reflected according to high genetic variations,and genetic variations carried out by microsatellite DNA markers is higher than structural loci. |
