Modeling epistasis in genomic selection
Web27 aug. 2024 · We have developed a rapid mixed model algorithm for exhaustive genome-wide epistatic association analysis by controlling multiple polygenic effects. Our model can simultaneously handle additive by additive epistasis, dominance by dominance epistasis and additive by dominance epistasis, and account for intrasubject fluctuations due to … Web6 jan. 2024 · Research Article The Addition of Epistatic Genetic Effects Increases Genomic Prediction Accuracy for Reproduction and Production Traits in Duroc Pigs Using Genomic Models Jian Cheng, Francesco Tiezzi, Jeremy Howard, Christian Maltecca, and 1 more This is a preprint; it has not been peer reviewed by a journal.
