TreeMix is a method for inferring the patterns of population splits and mixtures in the history of a set of populations. In the underlying model, the modern-day populations in a species are related to a common ancestor via a graph of ancestral populations. We use the allele frequencies in the modern populations to infer the structure of this graph. TreeMix uses large numbers of SNPs to estimate the historical relationships among populations, using a graph representation that allows both population splits and migration events.
