Genetic Values

Abstract

Some mating designs, such as factorials and diallels produce full-sib families. These mating designs allow decomposing the observed genetic variance into additive and non-additive genetic effects. Selection among full-sib families is common in some plant and animal breeding programs. If full-sib families can be propagated, non-additive genetic effects can contribute to selection gain. In addition, selection among progeny within crosses with known pedigree can be used to establish the next breeding population. In this chapter we demonstrate one diallel and one factorial example to partition the observed variance into additive and dominance genetic components. We then show an example of cloned progeny test data analysis for within-fullsib family selection.
