琅琊鸡Mx基因3’端部分序列PCRRFLP与序列分析
琅琊鸡 Mx基因 PCRRFLP 序列分析
2010/1/8
［目的］为琅琊鸡分子标记辅助选择、抗病育种提供依据。［方法］利用PCRRFLP技术对琅琊鸡Mx基因3’端片段的Hae Ⅲ的酶切多态性进行分析。［结果］琅琊鸡群体中存在Mx基因Hae Ⅲ酶切位点的多态性，且均有A、B 2个等位基因，基因频率分别为0.562和0.438。Mx基因Hae Ⅲ酶切位点的基因型分布在琅琊鸡群体中极显著偏离HardyWeinberg平衡状态(...
PCRRFLP技术检测嘉兴凤桥种猪氟烷基因
凤桥 猪 氟烷基因 PCR RFLP
2009/9/16
［目的］ 为凤桥镇通过合理利用氟烷基因提高猪肉品质奠定理论基础。［方法］ 从嘉兴县凤桥镇的规模化养猪场随机抽取种猪血样，通过PCRRFLP技术进行氟烷基因检测。［结果］ HhaⅠ内切酶的识别位点为5′GCG↓C3′。PCR扩增产物是含RYR1基因第1 843位点长度为659 bp的片段。如果猪的基因型为NN，由于未发生胞嘧啶C到胸腺嘧啶T的突变，可以看到2条带。如果猪的基因型为nn，由...
