QTL mapping in outbred half-sib families using Bayesian model selection

  title={QTL mapping in outbred half-sib families using Bayesian model selection},
  author={Ming Fang and Huan Liu and Deyu Sun and Yuan-Ming Zhang and Qin Zhang and Shengli Zhang},
In this article, we propose a model selection method, the Bayesian composite model space approach, to map quantitative trait loci (QTL) in a half-sib population for continuous and binary traits. In our method, the identity-by-descent-based variance component model is used. To demonstrate the performance of this model, the method was applied to map QTL underlying production traits on BTA6 in a Chinese half-sib dairy cattle population. A total of four QTLs were detected, whereas only one QTL was… CONTINUE READING
