Sex-dependent imprinting effect QTL (SbiQTL) and their patterns for body weights, growth and organ weights. Coordinates (Mb) are based on mouse genome build 36 http://www.ensembl.org webcite and location refers to F₂ cM map distances. Patterns are listed as Paternal = paternal expression, Maternal = maternal expression, Bipolar = bipolar imprinting, Under = polar underdominance, Over = polar overdominance, NS = non-significant. Loci were identified when the LPR for the overall effect of a locus exceeded the chromosome-wide or genome-wide threshold and they showed a significant sex by i interaction effect. The genome-wide significance threshold is given at an LPR of 3.41 and the chromosome-wide thresholds are given for each locus (in italics) as is the highest LPR for the locus. Traits shown in bold indicate a QTL effect.

The table lists the identified sex by imprinting QTL (SbiQTL) and effects for males and females separately. First, the SbiQTL is identified, followed by the trait affected and by marker name, the F2 map location in cM and the genome coordinate based on mouse build 36 http://www.ensembl.org webcite along with the confidence intervals. This is followed by the locus LPR and the chromosome-wide threshold (the genome-wide is 3.41), the estimates for the sex by i interaction, the corresponding standard error, the interaction LPR and the r² for the interaction effect. The next section details for males the additive a, dominance d, and imprinting i effects with their estimates, the estimates divided by the standard deviation and standard error as well as the corresponding LPR. Next, the imprinting patterns are given where 'Paternal' refers to paternal expression, 'Maternal' to maternal expression, 'Bipolar' to bipolar dominance, 'Over' to polar overdominance, 'Under' to polar underdominance and 'NS' to non-significant. This is followed by the genotypic values of the four ordered genotypes with their standard errors SE. We next present in the same order the equivalent information for females.
