Data
Allele frequencies of forensic STR markers by population and dataset. Explore them in charts, or download the tables for your own analysis. CE and NGS datasets are kept separate.
This section is designed to explore allele frequency variation across populations within well-defined forensic datasets.
Allele frequency datasets are organized by technology and study design. CE and NGS datasets are presented independently, as they are not directly comparable due to differences in laboratory methods, allele definitions, and analytical frameworks. Comparisons are valid only within each dataset.
These frequencies are derived from the STRs Local dataset of the SP-SMART portal (CESGA), comprising 3,809 genotyped individuals from diverse populations.
Population groups included
Central African Republic (Biaka Pygmies), Democratic Republic of the Congo (Mbuti Pygmies), Kenya (Bantu N.E.), Namibia (San), Nigeria (Yoruba), Senegal (Mandenka), Somalia, and South Africa (Bantu).
⚠️ Dataset notes (important)
The allele frequencies shown here come directly from the STRs Local dataset of SP-SMART / pop.STR.
STRhub does not modify, infer, reconstruct, or reinterpret any component of the STRs Local dataset. All methodological limitations originate exclusively from the structure, metadata availability, and design choices of the SP-SMART / pop.STR platform.
