The “single step approach” of Misztal et al (2009) and Christensen et al (2010) combines phenotypic, genomic and pedigree information into a single BLUP analysis. To adapt its implementation to most current genetic and genomic evaluation models, we propose an iterative solution procedure. Its main benefits are the fact that only moderate modifications of existing software are required and that it offers a framework for extension to more complex genetic or genomic models or their approximation.
