aSus scrofa chromosome
bSee Table 1
cChromosomal position in Kosambi cM
dSignificance of the QTL: * significant on a chromosome-wide level with P < 0.05; ** significant on a experiment-wide level with P < 0.05; *** significant on a experiment-wide level with P < 0.01
eThe percentage of phenotypic variance explained by the QTL
fAdditive effect and standard error. Positive values indicate the Duroc alleles result in higher values than Pietrain alleles; negative values indicate that Duroc alleles result in lower values than Pietrain alleles
gDominance effect and standard error
hThe closest markers were those markers around the peak, as near as possible (position of markers in cM)
# The imprinting effect and standard error was detected for HDL (1.03 ± 0.38) on SSC2, for TG (-3.18 ± 0.9) on SSC11 and for TG (-4.6 ± 1.58) on SSC17. When both the additive and the imprinting effects are positive or negative, the paternal allele expresses (maternal imprinting); otherwise the maternal allele expresses (paternal imprinting)
