Imputation accuracy of SNP on chromosome 12 measured by IA or by R²

Scenario	Genotype design			Accuracy of imputation
	Grandparents	Parents	Progeny	IA	R2
1	HD	HD	LowD	0.962	0.884
2	HD	LowD	LowD	0.833	0.408

Comparison of two measures of accuracy of imputation calculated using experimental data (tagSNP panel = 30 SNP), under two situations: 1) F₀ and F₁ at high density (HD), F₂ at low density (LowD), 2) F₀ at HD, F₁ and F₂ at LowD.
