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.
