Investigating the Performance of Frequentist and Bayesian Techniques in Genomic Evaluation
The genomic evaluation process relies on the assumption of linkage disequilibrium between dense single-nucleotide polymorphism (SNP) markers at the genome level and quantitative trait loci (QTL). The present s...
