Imputation accuracy in simulated data for low-density panels across categories of genotype information available on immediate ancestors. Imputation accuracies of the hybrid method (blue), AlphaImpute (red) and MaCH (green) for low-density panels and for six categories of animals based on which immediate ancestor was genotyped at high-density: both parents genotyped (Both); sire and maternal grandsire (SireMGS); dam and paternal grandsire (DamPGS); sire only (Sire); dam only (Dam); and other relatives (Other). The categories depend on the relationship of the animals to their most recent densely genotyped ancestors
