stochastic threshold
The peak height value in a DNA electrophoretic profile above which it is reasonable to assume that, at a given locus, allelic drop out of a sister allele in a heterozygous pair has not occurred in a single source DNA sample; due to the possibility of shared alleles in mixed samples, the presence of allele peaks above the stochastic threshold is no guarantee that allele drop out did not occur in mixed DNA sample profiles.
