  • Map position, marker interval associated with the highest lod score for the considered trait; No. of clusters, the number of clusters in the haplotype dendrogram that yields the highest lod score; r2 QTL, fraction of the trait variance due to the QTL, computed as Embedded Image ; r2 POLYG, fraction of the trait variance due to the polygenic background, computed as Embedded Image ; r2 RES, fraction of the trait unexplained by the model, computed as Embedded Image .
