摘要: 根据绵羊的遗传图谱及相关报道选择了位于4号和6号染色体上连锁的10个微卫星基因座,并在中国美利奴肉用品系群体中对这些基因座进行群体遗传学特性分析和体重的相关性分析。微卫星不同基因型在体重上的多重比较和微卫星标记对体重相关效应的F检验结果表明:紧密连锁的OARHH35 和BMS648 与体重间存在显著的相关性(P<0.05),有一个影响体重的QTL;染色体进行同源比较发现表明:在这两个位点之间可能有一个ob基因;6个微卫星基因座的基因型(BM9058(131/149 )、BM4621(149/181)、BM4311(119/119)、OARJMP8(131/145)、OARHH35(123/155)和BMS648(176/208))在体重上存在显著的差异。

Abstract: The amplified fragment length polymorphism of ten linkage microsatellite DNA loci in four and six chrosome according to the sheep linkage map and reports were detected in 162 meat sheep of Chinese Merino. By the multicomarison for weight of different genotypes in ten microsatellite loci and F test for the relativity of microsatellite markers with weight traits, the results showed that close linkage OARHH35 and BMS648 had a significantly positive correlation with weight (P<0.05). There is weight QTL and probably ob gene . BM9058(131/149)、BM4621(149/181)、BM4311(119/119)、OARJMP8(131/145)、OARHH35(123/155)and BMS648(176/208)had a significant difference in weigh.
