Mosaic diagram showing the contingency tables for each SNP-region combination. The area of the cell (rectangle) represents the quantities (numbers), the width of the cell represents the marginal probability in the row (region), the height of the cell represents the marginal probability in the column (number of animals per SNP within a region) and the colour of the cell represents the Pearson standardised residual with respect to independence (blue numbers higher than expected and red numbers lower than expected). The graphs were coloured on the basis of the Pearson residuals.
