摘要/Abstract

摘要： 为了评价中国山羊突变漂移平衡状况，以及近期是否经历瓶颈效应，本研究采用联合国粮农组织（FAO）和国际动物遗传学会（ISAG）推荐的9对微卫星引物，检测了中国39个地方山羊品种和1个引进山羊品种的遗传多样性。并在双相突变模型（Two-phase model of mutation,TPM )下，利用Wilcoxon标记秩检验(Wilcoxon signed-rank test)分析杂合过度是否显著。结果显示济宁青山羊显著杂合过度，表明该山羊种群近期可能经历瓶颈效应，在遗传育种和资源保存中应加以考虑。

Abstract: The present study was conducted to evaluate different Chinese goat breeds for mutation drift equilibrium and occurrence of any recent genetic bottleneck. A total of 2 027 animals from forty different breeds were analyzed with a set of 9 heterologous microsatellite markers. Under the two-phase model, all the goat breeds except Jining Qing goat were found to be in mutation drift equilibrium when evaluated by Wilcoxon signed-rank test. The result revealed significant heterozygosity excess suggesting possible cryptic demographic bottleneck in Jining Qing goat.
