¹QTL position is defined relative to the first marker (SNP) present in the genetic map for each chromosome; first marker positioned at 1 cM.
²For dominant QTL, the LRT is the test of model 3) against model 2). The variance explained by the QTL is given as additive /dominance
³ For imprinted QTL, the LRT is the test of model 4) against model 2). The variance explained by the QTL is given as maternal /paternal
*/** Significance threshold P < 0.05/0.01 assuming the null test statistic follows a χ²1 distribution
