| 摘 要： | 试验选择18月龄的夏南牛母牛40头,选用8个微卫星DNA标记,研究了夏南牛群体遗传变异,并分析了体尺性状与8个微卫星标记的关系.结果表明:8个微卫星标记BM2113、BM1824、ETH225、IDVGA2、IDV-GA46、IDVGA55、BM3413和TGLA44等位基因数分别为7,6,6,6,6,4,6和6;多态信息含量分别为0.764,0.775,0.786,0.701,0.723,0.570,0.759和0.776;杂合度分别为0.801,0.784,0.824,0.744,0.772,0.648,0.802和0.815.8个微卫星标记分别对夏南牛不同体尺性状存在正效应或负效应.

| Abstract: | Forty 18-month-old Xianan cows and 8 microsatellite DNA markers(BM2113,BM1824,ETH225,IDVGA2,IDVGA46,IDVGA55,BM3413 and TGLA44) were used to study the population genetic variation Xianan cattle and the relationships between the gene loci and their body size traits.The results showed that the these 8 microsatellite markers had 7,6,6,6,6,4,6 and 6 alleles,their(polymorphism information content) PIC was 0.764,0.775,0.786,0.701,0.723,0.570,0.759 and 0.776 and their heterozygosis was 0.801,0.784,0.824,0.744,0.772... |
