基于CHD基因和EE0.6基因遗传多态鉴定白枕鹤、丹顶鹤性别研究报告
野生动物学报, 2018 白枕鹤(Grus vipio)和丹顶鹤(Grus japonensis)是中国重点保护动物,为单态性鸟,很难通过外观和形态来进行性别鉴定,给人工繁殖造成很大困难。研究已发现CHD基因和EE0.6序列片段大小在非平胸鸟类W、Z染色体上均存在差异。基于此,本研究以无锡市动物园饲养的白枕鹤和丹顶鹤为研究对象,经PCR实验,对白枕鹤和丹顶鹤CHD基因和EE0.6序列的相关片段进行了特异性扩增。结果显示,这2种方法PCR扩增结果一致,并根据这一结果进行白枕鹤、丹顶鹤配对,均成功孵化出后代,表明该PCR鉴定结果可靠,
