遗传印迹或遗传印记(genetic imprinting) 

最近一二十年来 ,人们观察到来自父源和母源的同源等位基因在子代中会表现出不同的活性 ,此即称为遗传印迹。因此 ,在某些疾病中 ,会因父源基因或母源基因活性的不同而使病情表现出严重或轻微。通常认为遗传印迹产生的原因是 :在生殖细胞形成过程中 ,DNA甲基化

人类群体遗传空间结构异质性理论与定量分析方法研究 

人类群体遗传结构是指人群中所有个体的全部基因座的基因频率。目前,研究人类群体遗传结构的空间结构模式及其变化规律的定量分析方法,在分析群体遗传结构的空间特征、空间估计、群体空间关系和基因流动轨迹、遗传界线的识别、遗传结构空间成分的定量剖分等方面均存在局限性。为此,本研究遵循人类群体遗传学原理,将地质统计学、数学生态学、混...
