From: Development and validation of a horse reference panel for genotype imputation
Accuracy of imputation from medium-density to sequence level. Imputation was performed using a reference panel of 162 horses (RP2) and the software Beagle 5.1. a Accuracy of imputation per chromosome. b Accuracy of imputation against marker density of the medium-density SNP array per chromosome. The dashed line indicates a linear regression model of y = 0.017x + 0.232 (adjusted R-squared: 0.669, p-value: 1.2 × 10–8). c Accuracy of imputation against marker density of the medium-density SNP array for the ECA31 chromosome. The dashed line indicates a linear regression model of y = 0.017  + 0.233 (adjusted R-squared: 0.896, p-value: 1.6 × 10–13). d Accuracy of imputation plotted against the position on ECA31, with positions of the medium-density (MD) SNP array shown in orange
