These methods run much more rapidly on large datasets compared to model-based methods. The distance measure and the clustering algorithm can be somewhat arbitrary—i. It outputs each individual's coordinates along axes of variation instead of trying to classify all individuals into discrete populations, which may not always be the correct model for a particular population history.
It can also be used to estimate each individual's ancestry global ancestry. Designed for SNP data only. Sankararaman et al. It assumes uncorrelated SNPs. HAPMIX A program that uses a haplotype-based method to solve the problem of local ancestry inference in two way admixed population.
It uses haplotype information to accurately infer segments of chromosomal ancestry in admixed samples so it particularly useful in association tests for mapping disease genes in recently admixed populations and to do inferences about human history. Allows for uncertainty in model parameters, such as the allele frequencies in the parental populations, the number of generations since admixture occurred and the contribution of ancestry at each generation.

Estimating and visualizing population structure has implications for breeding programs beyond providing a correction for association analysis. Breeders may want to preserve structure within programs when it corresponds to specific market niches.
