Heatmap of the average genomic relationships within (diagonal) and between (off-diagonals) cross-validation folds. Folds (F) F1 to F6 belong to Yorkshire, and F7 to F10 to Landrace breeds. Each number represents the average genomic relationships of individuals within (diagonal) and between (off-diagonals) folds, with boxes with positive and negative numbers in red and purple, respectively
