| 摘 要： | 广西三黄鸡是我国著名的地方鸡品种,其肉质优良,具三黄特征。本研究采用30对微卫星标记分析广西三黄鸡群体的遗传多样性。结果共检测到212个等位基因,30个微卫星位点均表现出多态性,每个座位的等位基因数从2～11不等,平均等位基因数为7.067个;期望杂合度在0.500～0.847之间,均值为0.734,说明该群体具有较高的遗传变异水平;FIS值表明该群体的近交水平低,瓶颈效应分析结果表明该群体近期未经历过瓶颈效应。 |

| Abstract: | Guangxi three-yellow chicken is a light-body type breed with good meat quality,which is famous for its three yellow morphology features in China.In this paper,30 microsatellite makers were used to study genetic diversity of Guangxi three-yellow chicken.Microsatellite genotypes were derived,and allelic and genotypic frequencied,hererozygosities and gene diversity were estimated.A total of 212 alleles were distinguished.All the microsatellites were polymorphic,with mean allelic number of 7.067,ranging 2 to 11... |
