| Abstract: | Modern sequencing technology makes it possible to genotype polymorphisms with high throughput and high multiplexing. We have searched for and identified many loci with 2 or more SNPs within the expanse of a 200 bp single sequence run and show that when linkage disequilibrium is not complete these loci have multiple alleles detected as phase-known haplotypes. These microhaplotype loci (microhaps) are a powerful tool for individual identification, ancestry inference, and determining family/clan relationships. |
