We combined linkage (LA) and linkage disequilibrium (LDA) analyses (emerging the term ?LALDA?) for
genomic selection (GS) purposes. The models were fitted to a simulated dataset and to a real data of
feed conversion ratio in pigs. Firstly, the significant QTLs (quantitative trait locus) were identified
through LA-based mixed models considering the QTL-genotypes as random effects by means of
genotypic identity by descent matrix. This matrix was calculated at the positions of significant QTLs
(based on LA) allowing to include the QTL-genotype effects additionally to SNP (single nucleotide
polymorphism) markers (based on LDA) and additive polygenic effects in several GS models (Bayesian
Ridge Regression ? BRR; Bayes A ? BA; Bayes B ? BB; Bayes C ? BC and Bayesian LASSO ? BL). These
models combing all mentioned effects were denominated LALDA. Goodness-of-fit and predictive ability
analyses were performed to evaluate the efficiency of these models. For the real data, although
slightly, the superiority of the LALDA models was verified in comparison to traditional LDA models for
GS. For the simulated dataset, the models presented similar results. For both LDA and LALDA
frameworks, BA showed the best fitting through Deviance Information Criterion and higher predictive
ability in the simulated and real datasets. |
