| 摘 要： | 利用8个微卫星标记对5个绵羊品种(藏羊、兰州大尾羊、蒙古羊、小尾寒羊、无角道赛特)进行了遗传多样性分析.结果表明:5个绵羊群体的8个微卫星位点共发现105个等位基因,平均每个位点有13个,其中,在OarFCB128位点检测到的等位基因数最多,在BM8125位点检测到的等位基因数最少.多态信息含量、有效等位基因数及群体杂合度数据表明,小尾寒羊遗传变异最大,其次是蒙古羊、兰州大尾羊、藏羊,无角道赛特变异最小.根据Nei氏遗传距离用NJ法和UPGMA法构建的聚类图表明,兰州大尾羊与蒙古羊聚为一类,遗传距离最近,与无角道赛特距离最远. |

| Abstract: | The genetic diversity in 5 sheep breeds(Tibet sheep,Lanzhou large-tailed sheep,Mongolia sheep,Small-tailed Han sheep and Poll Dorset sheep) was analyzed by using 8 microsatellite DNA markers.The results indicated that,105 alleles for 8 microsatellite loci in 5 sheep breeds were discovered,the average allele number on a locus was 13.There were the most number of alleles in OarFCB128,and the least in BM8125.The data of polymorphism information contents(PIC),effective number of alleles(Ne) and heterozygosity(H... |
