摘要用PCR-RFLP技术，对新疆分布的准噶尔雅罗鱼、贝加尔雅罗鱼和高体雅罗鱼的mtDNA D-loop高变区约827bp进行了扩增，用ScaI、HinfI、AluI、DdeI 4种限制性内切核酸酶对56个样本的扩增产物酶切和RFLP分析，共检测到6种单倍型。准噶尔雅罗鱼存在2种单倍型：BDAA和BDBA；贝加尔雅罗鱼存在3种：AAAA、ABAA和ACAA；高体雅罗鱼只有1种。初步认为，准噶尔雅罗...
摘要：
牦牛的起源与属级分类学地位至今仍然存在一定的争议。我们测定了家养牦牛和野生牦牛线粒体控制区(D-loop)序列， 并以此构建牦牛和牛属、野牛属、水牛属以及非洲水牛属相关种的系统发育树。研究结果表明线粒体D-loop 区与Cyt b 基因序列在构建牛族的系统发育具有同样重要的价值。系统发育关系显示野牛属的灭绝种草原野牛与现存种美洲野牛先聚合为一单系群, 然后再和牦牛形成一单系分支, 表明牦牛...
