Polymorphism identification in goat DGAT1 and STAT5A genes and association with milk production traits
milk yield fat percentage dairy goat SNP PCR-RFLP SSCP additive effect
2015/6/24
Polymorphisms of DGAT1 and STAT5A genes in Xinong Saanen and Guanzhong goat breeds were investigated. PCR-RFLP, SSCP, and DNA sequencing were used to identify three SNPs: DQ380250:g.407_408insC in the...
Polymorphism identification in the goat MSTN gene and association analysis with growth traits
MSTN gene polymorphisms growth traits linkage disequilibrium
2015/6/9
The myostatin (MSTN) gene was studied as a candidate genetic marker for growth traits. We investigated polymorphisms of the MSTN gene in 664 individuals from four goat populations and applied PCR-SSCP...

The genetic diversity was studied using microsatellite DNA markers in Laoshan dairy goat (LS), Xinong Saanen dairy goat (SN), Guanzhong dairy goat (GZ), Banjiao goat (BJ) and Guizhou white goat (GW). ...
蒙古山羊和哈萨克山羊GOLA-DRB3基因的HaeⅢ酶切多态性分析Polymorphism Analysis of the GOLA-DRB3 Gene Digested with HaeⅢ in Mongolian Goat and Kazakh Goat
蒙古山羊 哈萨克山羊 GOLA-DRB3 PCR-RFLP
2008/1/10
摘要
采用限制性内切核酸酶HaeⅢ对蒙古山羊和哈萨克山羊GOLA-DRB3基因外显子2的285bp扩增产物进行了PCR-RFLP多态性分析，共检测到17种基因型，由A、B、C、D、E、F和H等7个复等位基因控制；通过酶切图谱分析发现蒙古山羊和哈萨克山羊的GOLA-DRB3基因外显子2的154、168和220位碱基表现出多态性。并对基因型频率和等位基因频率进行了统计分析，结果表明，GOLA-DR...
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...
