| 摘 要： | 采用24个微卫星标记对贵州白香猪2个品系的遗传变异进行了检测.试验结果表明,2个品系在24个微卫星基因座的平均等位基因、平均期望杂合度、平均多态信息含量和平均近交系数分别为2.1667、2.0417,0.4074、0.4188,0.3436、0.3249和0.5377、0.5605.结果 提示贵州白香猪具有一定的遗传稳定性,已成为一个稳定的遗传群体,符合封闭群动物的遗传特征.

| Abstract: | The polymorphism of 24 microsatellites in two Guizhou Bai Xiang pig breeds was analyzed. Results showed that:the average values of alleles,expected homozygosity,polymorphism information content (PIC),and inbreeding coefficients of 24 microsatellite loci was 2.1667,2.0417; 0.4074,0.4188; 0.3436,0.3249,and 0.5377,0.5605 respectively. The results suggested that the Guizhou Bai Xiang pig is a genetically stable breed and satisfies the genetic standard of a closed colony animal. |
