  • “Position marker” is the QTL’s distance from the nearest proximal marker on the chromosome while “Position centromere” is the telomeric distance from the most proximal marker on the chromosome in Haldane’s centimorgan. C.R. is the ±1 LOD confidence region. Also included are the raw and standardized additive (a, 2a/σp) and dominance (d, d/σp) genotypic values for maternal performance at each QTL. % VAR represents the percentage of phenotypic variation accounted for QTL with associated LOD score.
