Improving selection decisions with mating information by accounting for Mendelian sampling variances looking two generations ahead

Table 1 Overview of the selection criteria compared in this study

Focal generation	Criterion	Absolute threshold specific to	Unit of selection	References
Current	BV	Population	Individual
Progeny	ExpBVSelOff	Family	Mating	Schnell and Utz [16], called “Usefulness criterion”
Progeny	ProbSelOff	Population	Mating	Segelke et al. [7]
Progeny	Index5	Family	Individual	Bijma et al. [3]
Grandprogeny	ExpBVSelGrOff	Family	Mating	This study
Grandprogeny	ProbSelGrPrOff	Population	Mating	This study

BV = breeding value, ExpBVSelOff = expected breeding value of selected offspring, ProbSelOff = probability to select offspring, ExpBVSelGrOff = expected breeding value of selected grandprogeny, ProbSelGrOff = probability to select grandprogeny. Index5 is the fifth index tested by Bijma et al. [3] and describes the linearized probability that offspring are selected
