Estimated Error Rates on Three Chromosomes for Genotypes Generated by Three Different Procedures, All without Access to Pedigree Structure^[Note]

	Error Rate (No. of ObservedGenotypes) for Scoring Method
Chromosome	Genotyper^a	Manual Scoring	Quality Control^b
1	.0436 (821)	.0209 (744)	.0001 (601)
9	.0555 (511)	.0004 (399)	.0001 (211)
21	.1272 (151)	.0831 (103)	.0715 (90)

Note.— A lower bound of .0001 on error rates was enforced during maximum-likelihood estimation.

Data scored by Genotyper software, with no manual scoring.

Data cleaned by our quality-control procedures.
