Optimal haplotype reconstruction in half-sib families

11 pagesPublished: May 15, 2012


In the goal of genetic improvement of livestock by marker assisted selection, we aim at reconstructing the haplotypes of sires from their offspring. We reformulate this problem into a weighted binary constraint satisfaction problem with only equality and disequality soft constraints. Our results show these problems have a small treewidth and can be solved optimally, improving haplotype reconstruction compared to previous approaches especially for small families (<10 descendants).

Keyphrases: haplotpes, treewidth, weighted constraint satisfaction problem
