Genomic breeding values for ungenotyped individuals

Abstract Text:

Genomic information is now commonly used in routine genetic evaluations.  This is  usually in the form of genomic breeding values (GBVs) which have a high heritability but are generally confined to those animals with genotypes.   This can lead to anomalies when parents have GBVs and progeny do not.  By using a single-trait genetic evaluation, GBVs can be generated for related individuals.  It is most efficient to do this for genotyped individuals and their ancestors initially, and calculate mid-parent values for all other individuals.  A method for approximating accuracies for the relatives’ GBVs is described.
