Results from QTL mapping of the F2 population of Draba nivalis, indicating the 95% significance threshold value for each trait. The marker closest to the LOD score peak for the particular QTL is indicated (LOD score 1 indicate the LOD peak in the initial analysis and LOD score 2 indicate the LOD peak after the effects of other QTLs were accounted for). Percent PhenotypicVariation Explained (PVE) is indicated. Ratio indicates the proportion of homozygotes for AA (paternal alleles), heterozygotes, and homozygotes for BB (maternal alleles). Mean value for each trait is indicated for homozygote F2 individuals for paternal alleles (AA), heterozygote F2 individuals (AB) and homozygote F2 individuals for maternal alleles (BB), with inferred genotypes in italics.
