Quantitative genetic (animal) model example in R

Abstract

The following is just a quick introduction to quantitative genetic model, which is usually called animal model in animal breeding scenario. This model provides inferences on parameters such as genetic (additive/breeding, dominance, . . . ) values and possibly also co-variance components (additive genetic variance, heritability, . . . ). Very nice introduction to this topic is in Mrode (2005), which also gives a list of key references. We use example from this book and will therefore be very brief.
