Estimated feature frequencies at K = 4 shown as proportions. Abbreviations: Tk = Turkic, Tg = Tungusic, M = Mongolic, K = Koreanic, J = Japonic. The horizontal bar corresponding to each feature consists of feature frequencies (presence) in each of the four assumed ancestries. Each frequency lies within a range between 0 and 1. The range of each bar thus has a cumulative frequency between 0 and 4, i.e. max. 1 for each ancestry.
