Fig. 1From: Genomic prediction with epistasis models: on the marker-coding-dependent performance of the extended GBLUP and properties of the categorical epistasis model (CE)Comparison of the parametrization of the genotypic values in GBLUP and the categorical marker effect model CM: Black dots: genotypic values of the corresponding genotype of a certain locus. GBLUP parameterizes the genotypic values by a fixed effect (red dot) and a random effect determining the slope (blue line), whereas CM parameterizes by the fixed effect (red line) and independent random effects (blue lines) for each genotypeBack to article page
