Technical Abstract: Reliabilities of genomic evaluations increase when more genotypes are matched to more phenotypes. Options to expand genomic evaluation include genotyping more animals or markers; combining data sets across breed and geographical borders; using low cost, less dense marker subsets to obtain genotypes for a larger fraction of the population and phenotyping more animals or traits. Results and guidance are given for those topics, including simulated densities from 500 to 500,000 markers genotyped for 33,414 animals. New algorithms for haplotyping allow combining marker densities to obtain accurate genomic predictions for more animals with less expense. More options require more research to optimize experimental designs.
