2)  marker density
标记密度
1.
The precision of the prediction, indicated by the correlation with the unknown actual genome size from donor, was formulated by the variance and expressed as a function of the marker density.
预测的精确度则用有关方差的公式,以供体的实际片断大小(y)与根据标记基因型预测的供体片断大小(yp)的相关表示,并表达为标记密度的函数。
2.
Using Monte Carlo method, the effects of marker density on the accuracy of QTL mapping, measured with mean squared error (MSE) of QTL position estimates, were investigated for a granddaughter design under different population structures,heritabilities, sizes of QTL effect and QTL locations.
采用蒙特卡罗方法分析了在孙女设计中不同的群体结构、性状遗传力、QTL效应大小和QTL在染色体上的位置等各个因素不同水平组合下4种标记密度(标记间隔5cM,10cM,20cM和50cM)对QTL定位精确性(以均方误MSE为衡量指标)的影响,并从经济学角度探讨了应用于标记辅助选择(MAS)的QTL定位的最佳标记密度。
3.
It was important to ensure the effect of QTL mapping by increasing marker density in a certain extent,but as the map distance between two adjacent markers reach to a certain degree(5~10 cM),it could not improve the result of QTL mapping by further increasing marker density.
采用计算机模拟方法系统比较了目标数量性状的遗传力和标记密度对F2设计下单个性状数量性状座位(QTL)区间定位效果的影响。
