  1. Columns labeled "Total" contain the total number of errors of a specific kind for each laboratory. False allele size is when an allele was erroneously sized compared to the true size for single and double alleles. " = 1 bp" denotes that the erroneously called allele is a distance one from the true allele, whereas ">1 bp" means that the distance was greater than one. False homozygote is where the true genotype was a heterozygote, and false heterozygote is where the true genotype was a homozygote.
