Single Step, a general approach for genomic selection

A Legarra, OF Christensen, I Aguilar, I Misztal - Livestock Science, 2014 - Elsevier
Genomic evaluation methods assume that the reference population is genotyped and
phenotyped. This is most often false and the generation of pseudo-phenotypes is uncertain …
