  1. Misclassification matrix for the unrestricted error model with mean error rate per locus of 0.2%, 8% and 15.6%. The homozygous major allele genotype is coded as 0, the heterozygote as 1 and the homozygous minor allele genotype as 2. For each true genotype (0, 1, 2), the relative frequencies to observe the corresponding true or false genotypes are presented. Misclassification probabilities for an error rate per locus of 0.2% are based on Heid et al. [28].
