Simulated genotyping errors and resultant type I error rates.

Error Models §	Mistypes in total genotypes (%)	Misinheritance in mistyped trios (%)	Type I Err. (p ≤ 0.05) Rate (95% C.I.)
A	0.50	27	.0504 (.0499–.0508)
B	0.90	59	.0502 (.0498–.0506)
C	2.70	59	.0502 (.0497–.0506)
D	0.90	59	.0500 (.0496–.0505)
E	0.15	41	.0499 (.0495–.0503)
F	0.17	88	.0502 (.0498–.0507)
ALL	5.23	57	.0506 (.0502–.0511)

^§ A: mis-scoring genotype (x,x) as (x,x+2); B: mis-scoring genotype (x,x+2) as (x,x); C: short allele dominance; D: binning error; E: priming site mutation (Null allele); F: microsatellite mutation; ALL: all of above.
