It is believed that social preference, economic disparity, and heterogeneous environments are mechanisms for segregation. However, it is difficult to unravel the exact role of each mechanism in such a...
Mass segregation and fractal substructure in young massive clusters: (I) the McLuster code and method calibration

摘要黑腹果蝇(Drosophila melanogaster)中的分离变相因子[ Segregation Distorter(SD)]是一种非常典型的具有减数分裂驱动性质的特殊遗传因子。SD在世界不同地区的黑腹果蝇群体中广泛存在,通过杂交的方法测得其频率在1%-5%范围之内。首次在中国北京、青岛采集大量野生黑腹果蝇样本,对SD进行频率测定,发现SD在中国野生黑腹果蝇群体中也广泛存在,且频率与世界其...
摘要
对取自MAPMAKER软件小鼠F2群体(含333个体)的5个RFLP连锁标记数据作了共显性分子标记偏分离的分析。先确定选择类型的方程组(配子或合子)，随后采用Newton-Raphson迭代法估算标记间的重组值。在构建分子标记遗传图谱时，如果两个相邻标记均存在偏分离，最好采用纳入偏分离因子的估算方法。在估计F2群体标记间偏分离重组距离上,用连续χ2检测方法比传统χ2检测更为准确。Abstr...

摘要
在传统的数量性状多基因遗传模型基础上提出主基因-多基因遗传模型具普遍性，纯主基因或纯多基因遗传模型只是其特例。由此初步建立了植物数量性状遗传体系分离分析方法。目前该方法可以检验2～3个主基因的个别遗传效应、多基因整体的遗传效应和两者的遗传率。本文介绍这种分离分析方法的研究经过、主要进展及应用效果，并以实例说明其分析步骤、方法和效果。Abstract: Based on the trad...
