Table 1.

Genotype criteria for a contaminant (column 2) according to the genotype of the contaminated sample (column 1)

AR/genotype of a SNP of sample (A)	AR/genotype of the same SNP of the tested contaminant (B)	SNP compatible with contamination of sample A by sample B
0–0.005 (Ref/Ref)	0–0.25 (Ref/Ref)	Yes
0–0.005 (Ref/Ref)	0.25–1 (Ref/Alt or Alt/Alt)	No
0.005–0.25 (Ref/Ref)	0.25–1 (Alt/Ref or Alt/Alt)	Yes
0.005–0.25 (Ref/Ref)	0–0.25 (Ref/Ref)	No
0.75–0.995 (Alt/Alt)	0–0.75 (Ref/Alt or Ref/Ref)	Yes
0.75–0.995 (Alt/Alt)	0.75–1 (Alt/Alt)	No
0.995–1 (Alt/Alt)	0.75–1 (Alt/Alt)	Yes
0.995–1 (Alt/Alt)	0–0.75 (Ref/Alt or Ref/Ref)	No

Genotype compatibility (yes/no) is indicated in column 3
