| 摘 要： | 本研究利用内蒙古白绒山羊的7个父系半同胞家系共794个个体,用X染色体上的7个微卫星标记进行了系谱确认,构建了绒山羊X染色体遗传连锁图。结果表明,7个标记的等位基因数变化范围为9～14,杂合度在0.585～0.918之间,平均杂合度为0.726;多态信息含量在0.759～0.897之间,平均多态信息含量为0.834。构建的内蒙古白绒山羊X染色体遗传连锁图总长度139.4 cM,与英国罗斯林研究所公布的SM4.7绵羊连锁图标记顺序一致,可用于下一步的QTL定位研究。

| Abstract: | The 7 microsatellite markers on chromosomes X were used to construct a linkage map of Cashmere goats with a 794 members half-sib pedigrees after paternity testing. The results showed that the number of alleles for 7 markers was 9 to 14, the heterozygosity was 0.585 to 0.918， the average heterozygosity was 0.726, and polymorphic information content (PIC) was 0.759 to 0.897, the average polymorphic information content was 0.834. Length of the linkage map of chromosome X we built was 139.4 cM， and the sequence of loci was coincident with the SM4.7， and could be used in quantitative trait loci (QTL) searching in Cashmere goats. |
