TL;DR: A national single-step genetic evaluation with the pedigree relationship matrix augmented with genomic information provided genomic predictions with accuracy and bias comparable to multiple-step procedures and could account for any population or data structure.

TL;DR: BGF90 is a collection of software in Fortran 90 useful for breeding & genetics applications that consists of library modules and application programs that support a wide range of models, including those with multiple-correlated effects, multiple animal models and dominance.

TL;DR: This study investigated efficient computing options to create relationship matrices based on genomic markers and pedigree information as well as their inverses to implement a unified approach to genomic evaluations.

TL;DR: Genomic evaluation in beef cattle with ssGBLUP is feasible while keeping the models (maternal, multiple trait, and threshold) already used in regular BLUP, and using the inverse of the genomic relationship matrix calculated by an algorithm for proven and young animals that uses recursions on a small subset of reference animals.

TL;DR: The preconditionsed conjugate gradient implemented with iteration on data, a diagonal preconditioner, and in double precision may be the algorithm of choice for solving mixed-model equations when sufficient memory is available and ease of implementation is essential.
