摘要
选用西门塔尔牛、夏洛来牛、利木赞牛、安格斯牛、晋南牛、秦川牛、鲁西牛作为实验动物群体。分析了7个肉牛群体中8个微卫星位点(BM8125、RM113、TEXAN2、FCB48、INRA027、IDVGA37、BMS2137、ILSTS098、)的遗传结构和遗传变异。结果显示:8个位点中的前6个位点在7个群体中呈高度多态性,根据这8个微卫星多态性在8个群体间的遗传距离绘制的系统聚类图,能比较准确地反映这7个牛群体的地理分布和它们的亲缘关系。
Seven cattle breeds, including Simmental, Charolais, Limousin, Angus, Jinnan, Qinchuan, Luxi, were used as experimental population. The genetic variatipn ( gene frequency, heterozygosity, polymorphic information content and effective number of alleles ) and genetic structure of 8 microsatellite loci ( BM8125,RM113,TEXAN2,FCB48,INRA027,IDVGA37.BMS2137.ILSTS098 ) was analyzed in 7 cattle populations. The results showed that 6 of 8 microsatellite loci were highly plymorphic in these 7 breeds, The clustering dendrogram by genetic distance of the 8 microsatellites can reflect correctly geographical distribution and the relationship among the 7 cattle populations.
