From: Criteria for selecting microhaplotypes: mixture detection and deconvolution

Ternary plot of the probability of a qualitatively detectable mixture. The probability of having more than two haplotypes present, for a three locus system with allele frequencies of p, q, and r, is calculated for a set of genotypes from a random pair of individuals. The values range from zero along the margins with only two alleles present to the maximum at the “center” where all alleles are equally frequent.
