Inclusion of genomic inbreeding

Model

This section considers a GBLUP dominance model with a fixed regression coefficient for genomic inbreeding values. The regression coefficient can account for inbreeding depression. In theory, this model is expected to provide a more precise estimate of the dominance variance.

Files

The files are identical to those in the previous Example 13.4, except that the inbreeding coefficients are included in the model. The inbreeding coefficient is in the sixth column of the data file (mr134.dat). The model has an additional regression coefficient for the inbreeding coefficient as a covariate, defined in the parameter file (6 1 cov in mr134.par).

Solutions

The inbreeding depression (the regression coefficient) is \(-3.77\). The other solutions are similar to those calculated in Example 13.3.
