Austronesians profile trees

The combined dataset consisted in 3146 autosomal SNPs for 4025 individuals from 167 populations. It was analyzed using FRAPPE, with default settings, and for K ranging from 2 to 16.

For each value of K, the resulting ancestry profiles were averaged within each population, and a chi-squared distance between the average ancestry profiles were used to compute a distance tree using FastME. These trees were computed using the Austronesian populations of the sample. The Visaya Chabakano population is in a different colour because they speak a Spanish-based creole language, while the other populations speak Austronesian languages.
