| 摘 要： | 根据小鼠与牛的遗传比较图谱选择了牛第1号染色体上与weaver基因连锁的7个微卫星位点，并在新疆褐牛和荷斯坦牛群体中对这些微卫星位点进行了群体遗传学特性分析。结果表明：7个微卫星位点中，BM6438、BMS2321和BMS711属于高度多态位点，TGLAll6为中度多态位点。INRAll7、BMS4020和CA095属于低度多态位点。BM6438、BMS2321、BMS711和TGLAll6可作为奶牛产奶性能分析的微卫星标记位点。

| Abstract: | Genetic characterization of 7 microsatellite loci linked with weaver gene on BTA1 were analyzed among 192 Xinjiang brown cattle and 178 Holstein cattle.The results showed that among these 7 mi-crosatelliteloci, BM6438, BMS711 and BMS2321 were high polymorphic loci, TGLA116 was moderate polymophiclocus, BMS4020, INRA117 and CA095 were low polymorphic loci. BM6438, BMS711, BMS2321 and TGLA116 are potential DNA markers of milk production. |
