BW t-test BW EMMA p=3.8x10-6 explains 39% of the genetic variance component “ Although the strongest signals for the body weight after applying the mixed model are not genome-wide significant, they are concentrated in a region around 114 Mb in chromosome 8. This region almost exactly falls into the LOD peak of a previously known body weight QTL Bwq3. ”
