| 摘 要： | 本试验采用PCR方法,依据性别基因连锁理论,通过羽毛和血液,不提取鸽子基因组DNA,直接利用特异性引物对其CHD基因的特异性片段进行扩增,琼脂糖凝胶电泳检测,结果显示雄鸽仅有1条带,在700bp左右,雌鸽有2条带,分别在400与700bp左右;利用该检测方法对100羽性别未知的雏鸽进行了性别鉴定,结果为雌鸽48羽、雄鸽52羽,并通过剖解雄鸽的生殖器官进行验证,准确率达到100%。用建立的方法测定了2928羽雏鸽用于蛋鸽留种试验,结果表明,雌鸽为1411羽、雄鸽为1517羽。

| Abstract: | In this experiment, the primer pairs were designed, and polymerase chain reaction (PCR) technique to amplify the segments of the partial sex linked gene chromo-helicase-DNA-binding (CHD) to identificate pigeon's sex using feather pulps and blood.We found that two bands were demonstrated in all female egg-laying pigeons, and the sizes of them were 400 and 700 bp, respectively;In all male egg-laying pigeons, only one band appeared with length of 700 bp.100 unknown sex samples were successfully identified (52 males and 48 females).Based on the checking results between molecular electrophoresis of pigeons and the truly sex of maturity pigeons, we detected CHD gene in 2 928 early age pigeons using PCR amplification and electrophoresis in agarose gel.The PCR amplification results showed 1 517 males and 1 411 females. |
