摘要 对宁夏滩羊、得克塞尔、萨福克3个绵羊群体DLK1-GTL2印记化结构域的DLK1基因部分片段进行PCR-SSCP检测,结果表明:共检测到5个突变位点,分别为54507处的G→C突变、54553处的T→C突变、54592处的C→T突变、54620处的C→T突变、54638处的T→G突变,表现为5种单倍型D-1、D-2、D-3、D-4、D-5。对DLK1基因各SNP位点进行统计学分析表明,D1和D2、D3、D4、D5位点,D2和D3、D4、D5位点,D3和D5位点间存在强的连锁不平衡(P<0.01)。DLK1基因不同单倍型之间对宁夏滩羊、得克塞尔和萨福克群体的生长发育性状影响不显著(P>0.05)。
