We examine 31,011 PPY23 profiles at the population, metapopulation and world levels. Most haplotypes appear only once but a few have higher counts, including a set of 23 matching profiles in Delhi, India and a set of 16 matching profiles in Burkina Faso with one additional matching American African profile. We estimate FSTvalues to be used as “theta” (θ) in match probability calculations, following the method we used in our earlier survey of autosomal STR data. Match probability estimates using FˆST or the κ method of Brenner for a previously unseen profile are similar but differ for any profile previously seen.
