The average interspecific divergence was 3.860%, and special sites were found in each chicken breed which was the bases to identifying chicken breeds. The DNA taxonomy of Bar1 used NJ was consistent with morphological taxonomy among the six indigenous chicken breeds. However, the analysis of Bar2 sequences of COⅠindicated that they were lower polymorphism and no special site in most chicken breeds which was not benefit to identify chicken breeds. The DNA taxonomy of Bar2 used NJ was not consistent with morphological taxonomy among the six indigenous chicken breeds.
本研究选择的2段序列中,以Bar1序列648bp(712位点到1359位点)多态性最高,突变位点最多,为24个,品种间平均多态性为3.860%,6个鸡种在此序列中有各自不同的特异位点,NJ聚类分析6个品种基本被聚为不同的类别,与形态学分类基本一致,该COⅠ基因的Bar1序列用于这些品种鉴定是可行的;而Bar2序列进行序列多态性分析,由于其多态性低,大多品种没有其特异位点,NJ聚类分析6个品种基本被聚为不同的类别,与形态学分类基本一致,不利于品种鉴定。

There are three reasons for people's extensive interest in spin squeezing. Firstly, the spin squeezing is an effective method to overcome the limit in precision improvement set by Heisenberg Uncertainty Principle. Secondly, because of the relationship between spin squeezing and entanglement, the research in spin squeezing is of importance for quantum information. Lastly but not the least, the entanglement is one of fundamental physics problems, so research in thespin squeezing has both practical and theoretical significance.
论文摘要:自旋压缩的研究受到广泛关注源于三方面的原因:海森堡不确定关系的普遍存在是量子测量器件精度提高的最根本障碍,如何抑制它对精度的影响有着巨大的应用前景;自旋压缩与量子纠缠的密切关系使得自旋压缩的研究对量子信息有着重要的意义;另外,量子纠缠是物理有待探索的基本问题之一,所以对自旋压缩的研究既有应用方面的意义,也有着基本理论方面的意义。
