Aim & Objectives
Generate reliable Y-STR haplotype frequency estimates for Y-STR haplotypes to be used in the quantitative assessment of matches in forensic and kinship casework.
Assessment of male population stratification among world-wide populations as far as reflected by Y-STR and Y-SNP frequency distributions.
Provision of advanced tools and further resources concerning Y-STRs and Y-SNPs.
Current State of the Database
349,750 Minimal
309,090 Y12
289,405 Y17
106,444 Y27
103,280 Y23
46,773 Ymax
31,377 Y-SNP
