Download Structure 2.2 (released 4/2007)
The program structure is a free software package for using multi-locus
genotype data to investigate population structure. Its uses include inferring
the presence of distinct populations, assigning individuals to populations,
studying hybrid zones, identifying migrants and admixed individuals, and
estimating population allele frequencies in situations where many individuals
are migrants or admixed. It can be applied to most of the commonly-used
genetic markers, including microsatellites, RFLPs and SNPs. This method
was described in an article in Genetics
(155: 945-959). Extensions to the method were published in Genetics
2003 (Falush et al: 164:1567-1587) and Molecular Ecology Notes 2007 (Falush et al)
The new version includes a model to deal with dominant markers.
