SNP Genotype Calling and Estimation of Contamination from 299 European Sequenced Samples Across chromosome 20
(A) Numbers of heterozygous genotypes.
(B) Ratio of the numbers of nonreference homozygous genotypes to heterozygous genotypes (HET/HOM ratio).
(C) Estimated level of DNA sample contamination estimated from sequence data only.
