UK DNA-17 Allele Frequency Data for 16 STR Loci
Description
A dataset containing allele frequencies for 16 autosomal STR loci from the
UK Population dataset. Frequencies are provided for four
population groups: "White_-_EA1_&_EA2"
,
"Black_African_&_Caribbean_-_EA3"
, "Indian_-_EA4"
and
"Chinese_-_EA5"
.
Usage
UKDNA17freqs
Format
A named list of length 4.
Each element is itself a named list of 16 STR loci, with named numeric vectors of allele frequencies.
Details
Each population group is a named list of 16 elements, where each element
corresponds to a specific STR locus (e.g., D3S1358
, vWA
,
FGA
, etc.).
Each locus is represented as a named numeric vector:
-
Names: allele values (as character strings, e.g.,
"12"
,"14.2"
) -
Values: allele frequencies for that population group
An attribute "N"
is attached to each population list, specifying the
sample size (number of alleles) for each locus.
