So what to do with these situations where selected proportion and accuracy of selection cannot be established very well? One solution can be to predict the response to selection as the average genetic potential in the offspring of each mating based on the EBV of the sire and the dam. As we have seen in the chapter about genetic models, knowing the EBV in the parents only gives you some idea about the average EBV in of the offspring due to , if there is no information on the Mendelian sampling. Because: Aoffspring = ½ Asire + ½ Adam + MS. It will depend on the accuracy of the EBV in the parents to what extend the inaccuracy of the prediction of the genetic response will be further increased.

In conclusion: predicting genetic response to selection assuming a selected proportion and an accuracy of selection is very useful, but be aware of the (lack of) accuracy of your assumptions! |
