你的祖先是谁?在追溯祖先的过程中不一定会发现英雄和皇室血统,很可能你会发现自己的祖先是个罪犯,重婚者或者是一个讨厌鬼。 相似文献

“经20多位专家研究初步确认,50万年前的南京猿人已经具有两方血统。”中科院南京古生物研究所研究员穆西南近日披露了这个秘密。他说,南京猿人是在古代长江冰期,从北方来到南方,与我国发现的“元谋人”、“蓝田人”和“北京人”猿人化石不同,“南京人”的鼻梁高耸,估计和西方人有过基因交流。 相似文献

学界对中国传统社会中是否存在国际法是有争论的。本文以国际法理论为支撑,借助案例分析这一传统法学研究手段,探究中国传统的国籍观——“华民”,即通过对1843年,开海贸易前后,所发生的涉外事件进行案例分析;探究清政府认为在什么情况下,对什么人享有管辖权、保护权;中国传统的国籍观是由血统性原则、文化性原则、地域性原则等三部分组成。而同时满足以上三个原则的人,才是“华民”。 相似文献

从"产翁制"、"不落夫家"、"审新娘"等民俗以及舅权的产生、姓氏的演变几方面阐明了男女两性围绕血统之争曾经经历了一场持久而激烈的斗争。男性对于自身在创造生命方面具有与女性同样的价值的发现和确认是父系制建立的前提和基础。 相似文献

With biological and economic importance,threshold traits are discrete in phenotype but have the same polygenic genetic basis as quantitative traits. The traditional linkage analysis for quantitative traits is invalid for threshold traits due to their special characters. The transmission disequilibrium test (TDT) has received great attention recently in localizing human disease genes due to its simplicity and powerfulness. But TDT only deals with data from independent nuclear families and it will lose information about extended pedigree that incorporates information not only from parents and siblings but also from other relatives. The pedigree disequilibrium test (PDT) proposed by Martin in 2001 can be used to analyze the extended pedigree in human.In this study, PDT was introduced into the QTL mapping of threshold traits for farm animals, and was modified in order to accommodate the pedigree structures of farm animals.The modified PDT was renamed pedigree transmission disequilibrium test (PTDT) and its power and type I error were investigated and compared with that of PDT by Monte Carlo simulation. It was shown that PTDT is a robust and valid approach to mapping QTL of threshold trait. When the parental information is complete, PTDT and PDT are almost the same in terms of power and type I error. However, if the parental information is missing to a certain extent, PTDT is higher in power and lower in type I error than PDT. These results imply that PTDT can be a novel approach to QTL fine mapping of threshold traits based on the existing coarse mapping information. 相似文献
