| Abstract |
|
Simulation was used to examine the effect of linkage and flock size on the accuracy of estimation of genetic group effects and their associated variance in a single-trait across-flock evaluation. The accurate partitioning of genetic and environmental effects and the accuracy of estimation of genetic group variance is dependent on the level of linkage (at least 20%) among flocks, inclusion of genetic group effects in the evaluation model, size of genetic groups and the heritability of the trait. |
