  1. 1The number of attempted genotypes for all DNA inputs is N = 864. No amplification (No Amp.) genotypes reduce the number of genotypes available for concordance analysis. 2Loci 1–16 = TPOX, D2S1338, D3S1358, FGA, D5S818, CSF1PO, D7S820, D8S1179, TH01, vWA, D13S2317, D16S539, D18S51, D19S433, D21S11, AMEL.
