Figure 2

Interval mapping of parent of origin QTL effects for body-weight on chicken chromosomes 1, 4 and 5. The Y-axis shows the scaled rank of the test statistic obtained when compared to 1000 permutations of genotype within dam for 18 positions on chromosome 4 for conformation score. Mat and pat are testing for maternally or paternally expressed QTL respectively. Mat + pat is fitting both maternal and paternal expression and imp is testing difference between add model versus mat + pat model. Dashed line at top is 5% empirical linkage group-wise significance
