| 摘 要： | 本文以EAV(禽内源性反转录病毒片段 )为探针 ,EcoRI为限制性内切酶 ,对萧山鸡、SR92A系及其杂交后代进行了DNA指纹图谱的研究。结果表明 :EAV探针适合于鸡的DNA指纹分析 ,能产生清晰可辩的图谱。平均条带总数为11.384± 0 .84 4 ,两品种间、公母间条带总数均无显著差异。萧山鸡和SR92A系品种内相似系数分别为 0 .5 81、0 .5 11,高于品种间相似系数 (0 .2 31)。杂交后代相似系数为 0 .30 1。

| Abstract: | DNA fingerprinting of SR92A chicken,Xiaoshan chicken and their crossbred chicken were established with EAV(endogenous avian retroviral element)as the probe.It was revealed that similarity coefficient of crossbred chicken(0.301)was much lower than both of Xiaoshan chicken(0.581)and of SR92A chicken(0.511).The average number of bands are 11.384±0.844 |
