Investigating the impact of preselection on subsequent single-step genomic BLUP evaluation of preselected animals

Table 2 Details of the information used in the different types of preselection

Type of preselection	Preselection was based on	Information used in preselection model
Genomic	GEBV of the selection candidates^a	Complete pedigree^b, genotypes of all the animals in generations 13 to 15, phenotypes of all the animals in generations 11 to 14
Parent average	Average parental GEBV of the selection candidates^a	Complete pedigree^b, genotypes of all the animals in generations 13 and 14, phenotypes of all the animals in generations 11 to 14
Random	Random	Random numbers

^aSelection candidates were the animals in generation 15
^bThe complete pedigree consisted of all the animals from the founder generation (generation 0) to the most recent generation (generation 15)
