Single-step genomic evaluations from theory to practice: using SNP chips and sequence data in BLUPF90
Single-step genomic evaluation became a standard procedure in livestock breeding, and
the main reason is the ability to combine all pedigree, phenotypes, and genotypes available …

Single Step, a general approach for genomic selection
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 …
