Construction and forensic genetic characterization of 11 autosomal haplotypes consisting of 22 tri-allelic indels

Abstract Insertion/deletion polymorphisms (indels), which combine the advantages of both short tandem repeats and single-nucleotide polymorphisms, are suitable for parentage testing. To overcome the limitations of the low polymorphism of di-allelic indels, we constructed a set of haplotypes with physically linked, multi-allelic indels. Candidate haplotypes were selected from the 1000 Genomes Project database, and were subject to the following criteria for inclusion: (i) each marker must have a minimum allele frequency (MAF) of ≥0.1 in the Han population of China; (ii) markers must exist in a non-coding region; (iii) the physical distance between a pair of candidate indels must be
