First, we suggest a general and efficient method for updating 11 additive genetic effects, where the computational cost is independent of the 12 pedigree depth and only increases linearly with the size of the pedigree. Second, 13 we show how this approach can be used to draw inferences from a wide range of 14 animal models using the computer package Winbugs. Finally we illustrate the 15 approach in a simulation study, where data are generated and analysed (using 16...
