宿少勇 %A 顾东风 SU Shao-yong GU Dong-feng %J 遗传 %D 2004 %I %X In this article, we discussed two model-free methods for detecting genetic linkage for quantitative traits, Haseman-Elston regression approach and variance components approach. The former is a regression approach for detecting linkage based on the squared difference or squared sums in quantitative trait values of sib-pairs and their estimated marker IBD scores. The latter can jointly model covariate effects along with variance components, including genetic component and non-genetic sources of variability. We have outlined the model assumption, the algorithm and the extensions for the both methods. %K complex trait disease %K nonparametric linkage analysis %K quantitative trait %K H-E approach %K variance components
