摘要在广义线性模型的框架内模拟研究了家畜抗性等级性状的QTL定位方法，QTL参数的估计采用最大似然方法，比较了阈模型方法与一般线性方法的QTL定位效率，并对影响等级性状QTL定位效率的主要因素（QTL效应、性状的遗传力）进行了模拟研究，实验设计为多个家系的女儿设计，资源群体大小为500头。研究结果表明：在QTL位置参数估计及检验功效方面，阈模型方法具有一定的优势，对抗性等级性状QTL定位的功效也高...
不同QTL增效基因初始频率下标记辅助选择的效果
标记辅助选择 QTL增效基因 选择效果 随机模拟
2008/2/1
摘要 摘 要：采用随机模拟方法模拟了在一个闭锁群体内连续对单个性状选择10个世代的情形。在假定选择性状受一个位于常染色体上的QTL和多基因共同控制的情况下，采用动物模型标记辅助最佳线性无偏预测方法估计个体育种值并据此进行种畜的选留，并在此基础上系统地比较了QTL增效基因初始频率对标记辅助选择效果的影响。结果表明：当群体中QTL增效基因的初始频率较低时，选择所获得的QTL基因型值的进展会更大，标记辅...

多基因离散性状QTL连锁分析方法
离散性状 QTL 连锁分析 广义线性方法
2007/12/26
摘要动物中有许多重要的离散性状，与常规的数量性状类似，其遗传基础受多基因控制并受到环境因子的修饰。由于多基因离散性状的表型特殊性，利用常规的QTL连锁分析方法很难获得理想的统计效果，相应地发展了许多基于广义线性模型框架内的非线性方法。本文就目前离散性状的QTL连锁分析方法作简要综述，并对可预期的改进方法进行了展望。
