Accuracy of imputation (IA) for SNP on 60K chip using the 9K panel as tagSNP. Average accuracy of imputation for each chromosome using experimental data: Blue bars correspond to the case of F0 at high density (HD), F1 and F2 at low density (LowD). Red bars correspond to gain in accuracy of imputation when the F1 is genotyped at HD.
