Moderate stringency definition
Moderate stringency means that, of two DNA profiles, the alleles of a locus with the least number of alleles must be present in the corresponding locus of the other DNA profile. This stringency is used when comparing mixed DNA profiles with single DNA profiles. Because homozygotes are designated by a single allele value in CODIS, searching at moderate stringency with single DNA profiles also de- tects an allele drop-out in one of the DNA profiles compared (e.g. 12/13 will also match the apparent homozygotes 12/ or 13/);
