The probability of observing identical multi-locus genotypes by random chance as a function of MAF and the number of loci considered. The probability that two unrelated parasites would have an identical multi-locus genotype by chance (often referred to as identity by state) is shown on the y-axis on a logarithmic scale. The probability was calculated using loci with the highest minor allele frequencies (MAFs) (shown in yellow), loci with the lowest MAFs (blue). See “Methods” section for details on calculation (independence and neutrality assumed)
