分子遗传学的快速发展致使高密度遗传图谱的出现,高密度遗传图谱是研究数量遗传的分子基础的一种有用工具。利用遗传标记与QTL之间的连锁关系,我们能够评估QTL对数量性状的影响,与QTL紧密连锁的标记可被用来选择动物品种中的MAS,对本介绍了评估QTL效应的原理。
Rapid development in molecular genetics has leo to the Oevelopment ot Oense genetxc maps, wmcn is a poweful tool for studying the molecular basis for quantitive genetic variation. Using the linkage between genetic marker and QTL, we can research for the QTL influencing quantitative trait. Marker linked with QTL can be' used to take out MAS in animal breeding. In this paper, we introduced estimating QTL effects. that closely principles of
