Due to the ever-increasing data collected in genomic breeding programs. there is a need for genomic prediction models that can deal better with big data. For this reason. here we propose a Maximum a posteriori Threshold Genomic Prediction (MAPT) model for ordinal traits that is more efficient than the conventional Bayesian Threshold Genomic Prediction model for ordinal traits. https://steedaes.shop/product-category/transmission-accessories/
