China: STR Allele Frequencies from China

ChinaR Documentation

STR Allele Frequencies from China

Description

Comprehensive population allele frequency data for 70 autosomal Short Tandem Repeat (STR) markers from Chinese populations. This is one of the most extensive STR frequency databases available.

Usage

data(China)

Format

A data frame with 67 rows (alleles) and 71 columns. First column is Allele (repeat number), remaining columns are allele frequencies for each STR marker.

Details

This comprehensive dataset contains allele frequencies for 70 STR markers, including all standard forensic core loci plus an extensive set of additional markers. This enables very high discrimination power for identification purposes.

Core forensic markers included: CSF1PO, D1S1656, D2S441, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D10S1248, D12S391, D13S317, D16S539, D18S51, D19S433, D21S11, D22S1045, FGA, TH01, TPOX, vWA, SE33.

Extended markers include: PENTA D, PENTA E, D6S1043, D4S2408, D9S1122, and many others for enhanced discrimination.
