2015/6/8
The genomes of 6 sheep populations (Dorset, Texel, Black-Suffolk, Tan sheep, Small-tailed Han sheep, Tan and Small-tailed Han hybrid sheep) were screened using 7 microsatellite DNA markers to estimate...
Genetic polymorphism at the CSN1S1 gene in two Czech goat breeds
goat CSN1S1 allele frequency biodiversity
2015/6/4
The genetic polymorphism of the CSN1S1 (casein alpha-S1) locus was investigated in two endangered Czech goat breeds (White Shorthair and Brown Shorthair). These breeds are kept mainly for their good d...

采用扩增片段长度多态性（Amp-FLP）分型技术，调查中国北京地区汉族群体D1S1612、D18S535 基因座的遗传多态性，获得等位基因频率分布。结果显示， D1S1612检出9个等位基因，25种基因型， D18S535检出9个等位基因，27种基因型。两个STR基因座的杂和度（H）分别为0.779、0.887；个人识别率（Dp）分别为0.901、0.927;非父排除率（PE）分别为0.564、0...
为了调查X染色体上DXS6804、DXS9896和 GATA144D04等3个STR基因座在中国汉族群体的遗传多态性及其法医学应用价值，来用PCR和聚丙烯酰胺凝胶电泳对X染色体3个STR基因座进行分型，并检验女性基因型频率分布是否符合Hardy-Weinberg平衡，计算法医学常用各种概率。DXS6804、DXS9896和 GATA144D04的非父排除率分别为0.5990、0.6220、0.42...
摘要
利用4个微卫星标记（OarFCB11，OarAE101，McM218，McM38）对波尔山羊、太行山羊和河北奶山羊的等位基因频率、群体多态信息含量、有效等位基因数、杂合度和遗传距离进行了遗传检测，并测定了波尔山羊与河北奶山羊及太行山羊的杂交效果。结果表明：4个微卫星标记在波尔山羊、太行山羊和河北奶山羊3个品种中存在多态性，可以用于山羊遗传多样性的评估；从不同品种来看，太行山羊的遗传变异程度...
