Table 5 Proportion of phenotypic variance explained by polygenic, dam, paternal QTL and maternal QTL effects fitted in a pat+mat model at the position of the highest test statistic for pat+mat model versus no QTL

From: Detecting parent of origin and dominant QTL in a two-generation commercial poultry pedigree using variance component methodology

  1. The table shows the proportion of phenotypic variance explained by variance components. In the null model with no QTL, fitted polygenic heritability is 0.08, and dam component (Vc) estimated at 0.05 for conformation score and 0.03 for bodyweight.
