遗传力大小对cim法和MIM法有较大的影响，对IM法影响相对较小，尤其是在效应值的估计上。
Heritability had a greater influence on QTL mapping by CIM and MIM, but a little by im, especially the estimates of QTL effects.
在估计遗传及表型参数时，建立系统分组模型剔除非遗传效应的父系半同胞法优于简单的父系半同胞法；
It is more accurate to estimate genetic and phenotypic parameters from a hierachical classification model excluding non-genetic deviattion than from a simple paternal half-sib correlation.
随着QTL遗传力、样本容量和标记信息含量的增大，QTL位置以及效应估计值的准确度和精确度逐步提高。
The accuracy and precision of estimates of QTL position and effects will be enhanced as the increasing of QTL heritability, sample size and polymorphism information content of molecular marker.
