Legend Table 1. We used the F4 ratio to quantify the proportion of admixture in each of our Nepalese populations. Population X is being tested for admixture. Alpha is the proportion of population B ancestry in population X, while 1 – alpha is the proportion of population C ancestry in population X. See Additional file 2: Figure S3, a phylogeny, for further explanation
