Individual admixture proportions. Individual admixture proportions (q) and their associated 90% credible intervals in the VAR94 and VAR04 samples, estimated using VID (NSH) and RIN (ELW) as learning samples. A q value of 1 denotes a "pure" RIN individual, and conversely 0 denotes a "pure" VID individual. q values were ranked from lowest to highest. The analyses were conducted using STRUCTURE 2.2 [51,52]. a) q values in the VAR94 sample. b) q values in the VAR04 sample.
